D.o.t. Air Brake Coiled Hose Spring Brake Hose
This D.o.t. Air Brake Coiled Hose Spring Brake Hose is constructed from Nylon 6 (PA6) and Nylon 12 (PA12), with a hardness rating of 60D to 64D, designed to meet FMVSS 106 standards for commercial vehicle safety. It is rated for continuous operation at pressures up to 300 PSI and operates reliably across a temperature range of -40°F to +200°F. The internal diameter is available in 3/8 inch and 1/2 inch sizes, with quick-connect fittings compatible with standard heavy-duty air brake systems.
The material composition provides strong resistance to abrasion, cracking, and degradation from oils, greases, and hydraulic fluids. While the supplier lists PA6 and PA12, Nylon 11 (PA11) is also commonly used in this category for improved flexibility and moisture resistance, though it is not confirmed as standard for this product. The hose’s coiled design allows for extended reach and reduced kinking under dynamic movement, a standard feature in trailer and truck spring brake applications.
This hose is primarily sourced by fleet maintenance providers, OEM trailer manufacturers, and aftermarket parts distributors in North America, Europe, and Southeast Asia. Buyers typically order in bulk for integration into brake line assemblies or replacement kits. Packaging is usually in polyethylene sleeves or bulk coils, with MOQs and lead times requiring direct confirmation with the supplier. Incoterms are typically FOB Ningbo or CIF, depending on buyer preference.

Sourcing D.o.t. Air Brake Coiled Hose Spring Brake Hose from Ningbo Yuyao Langchi Plastic Factory - China Import Guide
Before placing an order, verify the exact material blend (PA6 vs PA12), hardness tolerance, and fitting specifications with the supplier. Request batch-specific test reports for pressure resistance, temperature cycling, and chemical compatibility. Confirm that the hose meets FMVSS 106 through documented test data, not just claim. Avoid accepting products without material certification or dimensional drawings.
Lead time is not stated and may vary from 15 to 45 days depending on order volume and seasonal demand. Incoterms are typically FOB Ningbo Port, but CIF or CFR may be negotiable. Payment terms often require 30% advance with balance against shipping documents. Confirm packaging method - bulk coils or individual sleeves - and whether protective caps are included on fittings to prevent contamination during transit.
Perform incoming inspection for wall thickness uniformity, coil integrity, and fitting torque strength. Use a micrometer to verify internal diameter against the specified 3/8 or 1/2 inch. Check for surface cracks, discoloration, or signs of moisture absorption. Request a Certificate of Conformance for each shipment, including batch number, test results, and date of manufacture. Retain samples for potential third-party lab testing if used in safety-critical systems.
