Stepped Cylindrical Coupling Body with Quick Connect Hose Coupling and Internal Ball-Retainer Cavity

Dongguan Jiarui Hardware Technology (Dongguan, Guangdong, founded 2012) turns and mills stainless steel quick connect hose couplings with stepped cylindrical body and internal ball-retainer cavity using turning, CNC milling, and internal cylindrical grinding at their circa 2,000 m² Dongguan facility; ball-retainer cavity diameter and thread class are both verified to match your print at first article, so the ball bearings seat correctly at the design engagement depth and the external thread engages the mating port at the correct torque without cross-threading. Cavity diameter, thread class, and body OD are recorded on the dimensional report before goods-out. IATF 16949 and ISO 9001 certifications govern process documentation for automotive, pneumatic, medical equipment, and OEM manufacturing quick connect hose coupling applications, supporting aerospace, military, and automation projects. Provide ball-retainer cavity dimensions, thread specification, OD tolerance, and stainless grade to get a proposal from our Dongguan production team and your drawing for quoting.
