II. Product Details (PRODUCT DETAILS)

1. All-Brass Core Components, High-Pressure Resistant & Corrosion-Proof

(1) Adaptation to High-Pressure Scenarios, No Safety Hazards

• High-Pressure Resistance: Quick connectors, tees, and shut-off valves can all withstand ≥140 PSi high pressure (far exceeding the conventional output pressure of 80-100 PSi for household air compressors and 120 PSi for industrial air compressors). They can be used in the pipelines of high-pressure pneumatic equipment (e.g., sandblast guns, high-torque wrenches) without bursting risks;
• Corrosion Resistance: The oxide layer on the brass surface can isolate moisture and impurities in compressed air, avoiding seal failure caused by internal rust (ordinary zinc alloy accessories rust in 3 months in humid environments, while this product can be used for more than 2 years).

(2) Precision Machining, Leak-Proof Sealing

• The thread precision meets ISO 228 standards (British pipe threads). Combined with nitrile rubber seals, the air leakage after installation is ≤0.1 L/min (far lower than the industry standard of 0.5 L/min), avoiding increased air compressor energy consumption due to air leakage (saving 15% of air compressor electricity costs annually);
• The male quick connector has a one-way valve design, which can block pipeline air flow when disconnected (no need to shut down the main air compressor). For example, when replacing pneumatic tools in a repair shop, only the connector needs to be pulled out, with no air leakage in the pipeline, improving maintenance efficiency.

2. Full Coverage of Multi-Specifications, Adapting to Most Scenarios

(1) Interface & Pipe Diameter Adaptation, No Additional Adapters Needed

• Interface Specifications: Quick connectors, tees, and shut-off valves provide G1/4" (for household small air compressors/small tools), G3/8" (for industrial medium-sized equipment), and G1/2" (for main pipelines of large production lines), which can be directly connected to air compressors and equipment of different specifications;
• Pipe Diameter Adaptation: Pipe clips cover 6-12mm common pneumatic hose diameters (applicable to both PU hoses and nylon hoses). One set of pipe clips can fix the pipelines of the entire house/ workstation, eliminating the need to purchase different specifications separately.

(2) Multi-Type Accessory Combination, Meeting Full-Process Needs

• Construction Stage: Use tees for branching, quick connectors for equipment connection, and shut-off valves for air flow control, no need to purchase additional accessories;
• Fixing Stage: Pipe clips can fix pipelines to walls or tabletops, avoiding joint loosening caused by pipeline sagging (e.g., long-term shaking of workshop production line pipelines easily causes joint air leakage, and the failure rate is reduced by 60% after fixing);
• Maintenance Stage: The spare seals (for shut-off valves and quick connectors) included with the set allow quick replacement of aging seals without re-purchasing the entire set of accessories.

3. Easy Installation, Accessible to Beginners

(1) Tool-Free/Less-Tool Installation, Time-Saving & Labor-Saving

• Quick Connector: Align and insert the male and female connectors to lock; press the release buckle to pull out when disassembling, completing the operation in 10 seconds (traditional threaded connectors require a wrench for tightening, taking more than 1 minute);
• Pipe Clip: Equipped with stainless steel screws, which can be fixed to the wall/tabletop with a screwdriver, no drilling tools required (impact drill can be used for assistance, or manual screwing into wooden tabletops);
• Shut-Off Valve: Knob-type switch, rotate clockwise to close and counterclockwise to open, no tools needed, operable with one hand (suitable for quick air shut-off in emergency situations).

(2) Detailed Design, Enhancing User Experience

• Dust Cap for Female Quick Connector: Cover when idle to prevent dust and moisture from entering the connector (avoiding seal failure caused by impurities), extending the connector service life;
• Anti-Slip Texture on Shut-Off Valve Knob: Increases hand friction, allowing easy rotation of the switch even when stained with oil;
• Adjustable Hole Position of Pipe Clip: The screw hole is oblong (±2mm adjustment range), allowing fine adjustment of the position during installation to adapt to uneven walls.

III. Application Scenarios (APPLICATION SCENARIOS)

1. Pipeline Expansion of Factory Pneumatic Production Lines (Core Scenario)

1. Pipeline Branching: Install a tee joint (G3/8" to G1/4") on the main pipeline (G3/8") to split branch pipelines (8mm PU hoses) for each production line, and seal the threads with Teflon tape (to prevent air leakage);
2. Equipment Connection: Install a G1/4" quick connector at the end of each workstation pipeline to connect the pneumatic wrench and spray gun (one-hand plugging, 10 seconds per piece);
3. Air Flow Control: Install a G1/4" shut-off valve in the middle of each branch pipeline to close the valve when the production line is shut down (no need to shut down the main air compressor, saving energy);
4. Pipeline Fixing: Fix the PU hose to the production line bracket with 8mm pipe clips (one every 80cm) to prevent pipeline shaking.
   Result: The pipelines for 3 production lines are constructed in 1 day (2 days with traditional accessories), with no air leakage (12% reduction in air compressor energy consumption). The shut-off valves switch flexibly (no failure after 8 months of use), and the pipe clips fix firmly (no pipeline sagging or deformation).

2. Workstation Pipeline Layout in Auto Repair Shops (Scenario 2)

1. Main Pipeline Construction: Lead the main pipeline (10mm nylon hose) from the air compressor (G3/8" interface), and split it to 4 workstations with tees (G3/8" to G1/4");
2. Workstation Configuration: Install a G1/4" shut-off valve + G1/4" quick connector at each workstation. Open the valve to use tools during maintenance and close it when idle (to avoid pipeline air leakage);
3. Pipeline Fixing: Fix the nylon hose along the wall with 10mm pipe clips (from the ground to the tabletop height, one every 50cm) to avoid interfering with repair operations.
   Result: The pipelines for 4 workstations are laid out in 3 hours (6 hours with traditional accessories). Each workstation can independently control air flow (no frequent tool plugging during maintenance). The quick connectors plug smoothly (used 20 times a day, no damage in 3 months), and the customer repair waiting time is reduced by 20%.

3. Household Air Compressor Pipeline Construction for DIY (Scenario 3)

1. Basic Connection: Connect the air compressor and 6mm PU hose (main pipeline) with a G1/4" quick connector, and arrange it along the wall to the workbench;
2. Branching & Control: Split 2 branches next to the workbench with a G1/4" tee, and install a G1/4" shut-off valve on each branch to connect the nail gun and sander respectively;
3. Fixing & Storage: Fix the PU hose to the balcony and wall with 6mm pipe clips (one every 60cm) to avoid pipeline tangling.
   Result: The household pipeline is constructed in 1 hour (no difficulty for beginners in the first operation). The air pressure is stable when the pneumatic tools are working (no obvious pressure drop). There is no air leakage in the pipeline after the shut-off valve is closed (reduced air compressor start-stop frequency). The pipe clips fix firmly (no pipeline sagging affecting operation).

IV. Frequently Asked Questions (FAQ)

Q1: Air leakage still occurs after inserting the quick connector. What is the reason?

1. Check Insertion Depth: Incomplete insertion leads to incomplete sealing — ensure the male connector is fully inserted into the female connector until a "click" sound is heard (locked in place). If insertion is difficult, apply a small amount of pneumatic special lubricating oil (to avoid damaging the seal ring);
2. Seal Inspection: Aging or deformation of the nitrile rubber seal ring in the female connector causes air leakage — remove the female connector's dust cap, take out the seal ring (gently pick with a small screwdriver), and replace it with the spare seal ring included with the set (pay attention to the installation direction, with the convex side facing the male connector);
3. Impurity Cleaning: Dust and impurities in the connector affect sealing — blow clean the inside of the male and female connectors with compressed air, or wipe the seal ring surface with alcohol cotton to avoid seal failure caused by impurities.

Q2: The tee joint produces air flow noise under high pressure. Is it due to excessive pressure or installation issues?

1. Pressure Adaptation Check: If the air compressor output pressure is ＞160 PSi (maximum pressure bearing of the tee), high-speed air flow will produce noise — adjust the air compressor pressure to below 150 PSi (most pneumatic tools do not require pressure exceeding 120 PSi), or replace the tee with a higher pressure-bearing one (contact the merchant to purchase the 180 PSi specification);
2. Installation Sealing Check: Loose threads or no Teflon tape will cause air flow leakage from gaps and produce noise — turn off the air compressor, tighten the tee threads clockwise with a wrench (moderate force to avoid thread stripping). If noise persists, disassemble and wrap 1-2 layers of Teflon tape before reinstalling;
3. Pipeline Matching Check: Mismatch between the tee interface specification and the pipeline (e.g., G3/8" tee connected to G1/4" hose) causes air flow turbulence — confirm that the tee interface matches the hose specification (e.g., 8mm hose with G1/4" tee), and install an adapter if necessary.

Q3: The pipeline still sags after being fixed with pipe clips. How to solve it?

1. Pipe Clip Specification Check: If the pipe clip's applicable diameter is smaller than the actual hose diameter (e.g., 6mm pipe clip for 8mm hose), it will cause unstable fixing — replace with a pipe clip matching the hose diameter (e.g., 8mm pipe clip for 8mm hose), ensuring the hose is fully embedded in the pipe clip slot;
2. Installation Spacing Adjustment: Excessive pipe clip spacing (＞80cm) causes sagging in the middle of long pipelines — add pipe clips at the sagging position (reduce spacing to 50-60cm), especially at pipeline bends (an additional pipe clip is required to distribute stress);
3. Installation Method Optimization: If the wall is uneven, place a 1mm thick rubber pad between the pipe clip and the wall to ensure the pipe clip is fully attached to the wall, avoiding pipeline shaking caused by gaps.

Q4: Can a small household air compressor (G1/4" interface) use this set of accessories? Is an additional adapter needed?

1. Interface Compatibility: Most small household air compressors have G1/4" interfaces. The quick connectors, tees, and shut-off valves in the set all have G1/4" specifications, which can be directly connected without adapters (e.g., air compressor → G1/4" quick connector → 6mm PU hose → G1/4" shut-off valve → pneumatic tool);
2. Pressure Compatibility: The output pressure of household air compressors is mostly 80-100 PSi, and the maximum pressure bearing of the accessories is ≥140 PSi, fully meeting the needs with no safety hazards;
3. Usage Suggestion: When constructing household pipelines, set the pipe clip spacing to 60cm (to avoid pipeline sagging due to excessive length). Cover the quick connector with a dust cap when idle (to prevent dust entry), and check the seals every 3 months (replace with spare parts if aging).
