Teflon Corrugated Hose with SS304/316 Flanges – High-Flexibility, Chemical-Resistant PTFE Bellows

Virgin PTFE | -70°C to 260°C | RoHS Compliant

Manufactured by Shenzhen Teflon New Material Technology Co., Ltd

The Teflon Corrugated Hose is engineered for demanding fluid-handling applications where vibration, misalignment, and thermal expansion can cause metal piping to fail. Made from 100% virgin PTFE combined with stainless steel flanged ends, this hose provides unmatched corrosion resistance, flexibility, and long operational life.

Product Overview – Flexible Teflon Corrugated Hose for Industrial Applications

This hose is designed as a flexible connector for pumps, compressors, dosing systems, filling lines, and rigid pipe networks.
The helical PTFE bellows allow tight bending without kinking, while stainless steel flanges ensure strong sealing and easy installation.

Operating temperature: -70°C to +260°C

Suitable for chemical, pharmaceutical, food, and water production systems.

Chemical Resistance & High Purity Performance

Virgin PTFE is chemically inert to nearly all industrial chemicals, including:

• Strong acids (H₂SO₄, HNO₃, HCl)

• Alkalis and caustic solutions

• Organic solvents

• High-purity water & pharmaceutical media

Its smooth, non-stick inner surface prevents contamination and makes cleaning easier.

Industry Applications

• Chemical Processing – Acids, alkalis, solvents

• Pharmaceutical Manufacturing – High-purity media

• Food & Beverage – Clean transfer lines

• Water Treatment – Dosing chemicals & aggressive effluents

• Industrial Machinery – Pump, compressor, load-cell connections

• Pipeline Systems – Thermal expansion compensation

Vibration Absorption & Expansion Compensation

The corrugated PTFE bellows design absorbs:

• Pump vibration

• Axial & lateral movement

• Thermal expansion & contraction

This prevents metal fatigue and significantly reduces stress on connected equipment.

Available Flange Standards (ANSI / JIS / DIN)

Choose the flange type that matches your piping system:

• ANSI 150 / 300

• JIS 10K

• DIN PN16

Flanges can be fixed or floating for easier alignment.

Quality Control & Testing

Every hose undergoes:

• Visual inspection

• Dimension verification

• Hydrostatic pressure test (100% leak test)

Additional third-party tests (SGS/CTI) available on request.
