Import Bundy Tube — Buy in Bulk from Supplier in China

KST Technology Inc., based in Shandong, China, supplies Bundy tubes that meet ASTM A254 and SAE J527 standards. The tubes are offered in both double-wall and single-wall constructions. Available plating finishes include yellow zinc, white zinc and copper, as specified by the buyer. Standard size offerings include 3.2 mm x 10.5 mm and 4.76 mm x 12.5 mm dimensions, with lengths supplied as coils, straight boom lengths, cut-to-length or fabricated assemblies.

Copper is the primary material, providing good corrosion resistance and flexibility for hydraulic and fuel line applications. The double-wall design adds extra reinforcement, while the single-wall version offers lighter weight for space-constrained installations. Industry practice typically expects a pressure rating around 250 bar and an operating temperature range from -40 C to 150 C for such tubing. These typical performance figures align with the requirements of automotive brake, clutch and power-steering systems.

Buyers such as vehicle manufacturers, aftermarket parts distributors and equipment importers use these Bundy tubes for brake lines, fuel lines, transmission and air-conditioning circuits. KST Technology Inc. can provide the tubes in bulk quantities, but the minimum order quantity is not disclosed in the listing and should be confirmed directly. Prospective importers should request detailed product data sheets, material certificates and any applicable test reports before placing an order. Shipping terms, incoterms and payment conditions are negotiated with the supplier on a case-by-case basis.
