CNC Turning of a Steel Connector for the Hose and Coupling Industry

Allied Precision was contracted to fabricate a custom Connector spud for a hose and coupling manufacturer. Employing our advanced CNC lathe, we performed turning, boring, and threading processes on C1215 steel component. This process allowed us to maintain dimensional tolerances of ±.005″, and angular tolerances of ±1°. Finished dimensions for this part were 1-3/8″ high, a 1-7/8″ hex, extruded threads of 1.814″/1.812″, and cut threads of 1.877″/1.865″.

The part underwent tumbling deburring to cleanse any remaining particles from machining, preparing it for the corrosion resisting zinc plating process. The cleaned parts were immersed into the zinc solution and the proper current applied. The plated parts were part marked for identification and branding and shipped to this east coast customer. We produced 10,000 units, packaged and shipped with a turnaround time of 3-4 weeks.

The 3/4″ Connector spud was fabricated according to customer specifications, upholding rigorous industry standards for quality and integrity. This spud features a polymer seat, which aids to form a chemical resistant, leak-proof seal.
