QA1 Tube Adapters

QA1’s weld-in tube adapters are CNC machined to precise tolerances from special easily weldable chromoly steel. Available in a large assortment of sizes to fit most popular tubing, they are an effective way to adapt rod ends or QA1’s Rebuildable Bearings to a variety of applications. Available in both right and left hand thread styles, with the left hand units marked with a machined groove for easy identification. Also available in select sizes with integrated hex; weld-on hexes sold separately.
