3508510LE6KS Nylon Pipe is a rigid and flexible pneumatic pipeline for the air brake circuit of JAC HFCN721 light truck. It transmits compressed air between air reservoir, brake valve and brake chamber to realize brake control. This aftermarket replacement pipe resolves slow brake response, air pressure loss and brake failure warning triggered by pipe cracking, brittle fracture and joint air leakage of old nylon tubes. Stable air transmission ensures reliable braking performance for light trucks operating on busy urban delivery routes with frequent braking operations.
Product Advantages High-quality nylon material features low weight, good pressure resistance and anti-aging property. It resists corrosion from water condensate and brake oil inside the air circuit. The pipe maintains stable shape under normal working pressure and can withstand slight bending during assembly. Each pipe undergoes air tightness and pressure burst test before shipment, standard outer diameter to match original quick push fittings.

FAQ
Q1: What is the obvious sign of air leakage on this nylon brake pipe?
A1: Continuous hissing sound, air pressure drops fast and the air compressor runs more frequently.
Q2: What will cause nylon pipe to become brittle and crack prematurely?
A2: Long-term exposure to sunlight, close contact with high-temperature components and chemical oil contamination.
Q3: What rule should be followed when cutting and connecting nylon pipe?
A3: Cut the pipe end flat and insert fully into quick connector to guarantee reliable sealing.
