Brass Elbow Fitting with Hose Barb Fittings and Hexagonal Mounting Boss

Zhejiang Bolei Electric (Taizhou, Zhejiang, established 2008) machines brass hose barb fittings with O-ring groove and hexagonal mounting boss at their more than 30,000 m² Taizhou facility, IATF 16949, ISO 9001, ISO 14001, ISO 45001, and CE marked, with barb OD taper profile, O-ring groove diameter, and thread pitch diameter cross-checked with your released dimensions at first article sign-off and verified in batch sampling. Barb OD taper angle outside the design nominal changes hose insertion force and reduces retention force at the pull-off load; steep taper requires excessive insertion force that splits standard hose wall, while shallow taper allows the hose to disengage below the design blow-off pressure in hydraulic and pneumatic applications. Bolei serves pump & valve, battery, aerospace, hydropower, and wires & cables hose barb fittings applications using Swiss machining, five-axis milling, and milling & turning. The facility serves automotive, military, and semiconductor clients. For quoting, include barb taper profile, O-ring groove dimensions, thread class, and brass grade and our Taizhou production team will quote accordingly.
