Import Bundy Tube — Buy in Bulk from Supplier in China

The Bundy Tube offered by Qingdao Kst Technology Inc. is a low‑carbon steel hydraulic tube that complies with ASTM A254 and SAE J527 specifications. It is supplied in both double‑wall and single‑wall constructions, allowing selection based on pressure requirements. Available plating options include yellow zinc, white zinc, copper and PVF, each providing a different level of corrosion protection. The supplier lists length formats as coils, straight boom lengths, cut‑to‑length, or complete fabricated assemblies.

In the hydraulic‑brake market, bundy tubes are typically produced with outer diameters ranging from 2 mm to 12 mm and wall‑thickness tolerances of ±0.1 mm, which aligns with the typical dimensions for this class of product.
