This 3/8 inch Bundy pipe is a double-wall brazed steel tube manufactured from low carbon steel grades SAE 1006 and SAE 1008, engineered specifically for hydraulic brake and fuel line applications in passenger and commercial vehicles. The outer diameter spans 4.76 mm to 15 mm, with wall thickness and burst pressure ratings typical for automotive OEM brake tubing standard SAE J527 or DIN 74234. The double-wall brazed construction creates a leak-proof seam capable of withstanding the cyclic pressure pulses generated by modern ABS and ESC braking systems.
The tube receives protective coatings selected for the target operating environment: copper for general corrosion resistance, zinc variants (silver, gold, olive) for salt-spray protection, PVF (polyvinylidene fluoride) for aggressive underbody exposure, and galfan (zinc-aluminium alloy) for extended service life in coastal or winter-road conditions. Material certification to SAE 1006/1008 ensures consistent formability during flaring and bending operations without work-hardening cracks. The brazing alloy, typically copper or copper-zinc, penetrates the lap joint to create a metallurgical bond stronger than the base metal in shear.
Supplied forms include cut-to-length straight sections, pancake coils for manual bending on site, spiral rolls for automated brake-line manufacturing cells, and pre-fitted assemblies with SAE or DIN standard tube nuts and flare fittings. Buyers span OEM brake system integrators, Tier-1 automotive suppliers, aftermarket wholesale distributors, and specialist vehicle conversion workshops. Trade shipment is under HS code 8708.31; buyers should confirm whether Shaanxi Yongrui offers mill test certificates, third-party inspection reports, and specific Incoterms for containerised or air-freight delivery.

Before placing an order with Shaanxi Yongrui Industry Co., Ltd., verify the supplier's business licence, export licence, and any ISO 9001 or IATF 16949 quality system certificates through independent documentation rather than profile claims. Request a factory audit report or third-party inspection summary, and ask for sample tubes with full mill test certificates so your engineering team can verify dimensional accuracy, coating adhesion, and burst pressure before committing to bulk production. Confirm that the HS code 8708.31 classification matches your customs broker's interpretation to avoid duty disputes on arrival.
Logistics from Xi'an, Shaanxi Province typically route via rail or road to Shanghai, Qingdao, or Tianjin port for sea freight, or to Xi'an Xianyang International Airport for air cargo. Lead time, Incoterms, and payment terms are not stated in the profile and must be negotiated directly. Standard Chinese export terms often operate on FOB major port with T/T 30 percent deposit and 70 percent against copy of B/L, or L/C at sight, but Shaanxi Yongrui's exact position is unknown. Clarify whether they offer container consolidation with other automotive parts buyers to reduce freight cost for smaller orders.
Inspect each delivery for coating uniformity, absence of rust under film, and dimensional compliance using go/no-go gauges for OD and wall thickness. Require a certificate of conformity referencing SAE J527 or your specified standard, plus a material test report with chemical composition and mechanical properties. For critical brake applications, engage a third-party inspector such as SGS or Bureau Veritas to witness hydrostatic burst testing and pressure-pulse cycling on a sample basis. Retain inspection records for product liability traceability, and confirm with Shaanxi Yongrui their batch numbering system and recall communication protocol.
