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.

For valve couplers, the coupler is pictured with our Series 250 nipple as an integral assembly.

Series 93 is designed for large unrestricted flow rates and instant positive connection to either straight or bell type tubing. Slide the coupler onto the tubing until seated and push down on the mechanical lock/lever to make a positive seal. A cam-locking device grips uniformly and firmly without damage to steel, copper, brass, or plastic tubing. The tube seal will accept tubing out of roundness conditions up to 2%. Extended seal life reduces connector maintenance costs.

STRONG: Holds pressures from 25 microns up to 1000 PSIG.

TEMPERATURE RANGE: 0-250° F (0-121° C).

SAFE: Built-in safety valve automatically vents system pressure before the connector can be removed from the tube. Blow-off or seal loss by accidental bumping is eliminated.

FLEXIBLE: Easily repairable with internal parts that are interchangeable allowing the same connector body to fit all four tube sizes. When using vacuum and ester oils, please contact our Order Department (937-299-5594) for help with selecting the correct elastomer for the particular application.

For manual operation, slide the coupler onto the tubing until seated and pull the sleeve back to make a positive, leak-free seal. To release, simply push the sleeve forward. The field-proven cam locking device grips uniformly-firm but gently without damage to steel, copper, brass, or plastic tubing.

the long-life tube seal reduces couple maintenance costs and can easily be replaced. The seal accepts out of roundness conditions up to 2%.

The Series 91 TQC hold pressures from 25 micros up to 500 psi, proof pressure 4000 psi.

A built-in valve automatically vents system pressure before the coupler can be removed from the tube for operation safety. Blow off or loss of sealed connections are eliminated.

Five internal parts are quickly interchangeable allowing the same connector body to fit all three tube sizes. This simple interchangeability allows for changing refrigerants and oils.

Seals are available in Neoprene, Nitrile, and Fluorocarbon for specific applications.
