Series 91 Tube Quick-Connect Coupler

  • Product Code: Series 91 Tube Quick-Connect Coupler

Description


These tough, compact, lightweight couplers utilize heat-treated parts for interchangeability and long life. Oxide and nickel finishes are corrosion resistant. They provide a large, unrestricted flow rate for a variety of production uses while minimizing material loss during coupling and uncoupling.

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

Series 91 is designed for large unrestricted flow rates and instant positive connection to straight tubing either manually or by use of automated euipment. 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 500 psig.

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

SAFE: A built in venting process occurs prior to disengagement for operator safety.

FLEXIBLE: Easily repairable with internal parts that are interchangeable allowing the same connector body to fit all three 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.
