These tough, lightweight PCU Couplers and Nipples utilize heat-treated parts for interchangeability and long life.  They provide a large unrestricted flow rate for a variety of production uses while minimizing process material loss during coupling and uncoupling.

An eight (8) ball detent lock provides instant positive coupling.  Simply pull back the grooved locking ring on the coupler, slide the coupler over the nipple, and push together until the lock ring snaps to its “lock position”.

Because of the unique design of the Series 410 Models 66 and 67 Coupler and Nipple assemblies, they are able to be built using inexpensive O-ring seals which provide positive leak-tight shutoff.  They will hold pressure from vacuum to 1000 PSIG.

The standard Series 410 Coupler and Nipple assemblies can be built with a variety of seal compounds to satisfy your application.  Neoprene compound is generally used for R-22, R410, R404a, and compressed air.  Buna-N is generally used for HFC-134a with lubricants.  Other applications, which require oils/lubricants, please contact our Order Department at (1-937-299-5594) for help in selecting the correct compound for your particular application.

The Series 410 Models 66 and 67 Coupler and Nipple assemblies complement our Series 500, 91, and 93 Tube Quick Connect (TQC) Couplers to permit unrestricted flow.
