Precision CNC Turning of a Stainless Steel Elbow Hose End Fitting for the Defense Industry

A government defense contractor needed a company with the experience and reputation for high quality work to provide them with a custom machined 90° elbow fitting, utilized for ship refueling and controlled fluid transfer. Allied Precision was contracted to take on the job, utilizing our advanced CNC lathe to turn and bore 316 stainless steel to the specified size and shape, maintaining tight tolerances of +0.002″ and ± 30 MIN (angular) throughout. This fitting has a finished outer diameter of 6.62″ and inner diameter of 5.27″, with a raw machined finish. This part was cleaned and smoothed with our deburring process, 200 units were packaged for shipment to the customer on the East Coast. Turnaround time for this project was 3-4 weeks.

This elbow fitting was constructed catering to customer requirements, keeping to the standards set by MIL-STD-278, with thorough testing and inspections performed. This part passed pressure testing of 600 psi for 3 minutes. This defense application is just one example of the precision CNC machined work Allied has been providing customers for over 20 years.
