​TC Tube Connectors

1/8" to 2-1/4" O.D. (3 to 57mm)


The TC Tube Connector were originally developed for production lines on refrigeration coils, but have also earned overwhelming acceptance for use on compressor units, heat exchangers and any other assemblies which require a quick, easy and efficient way to attach pressure lines to straight end tubing

For short length tubes 1/4" to 1" O.D. (7 to 25 mm)


The RTC Tube Connectors have been specifically designed for use in applications where only a short length of tube is available for engagement. Just attach the connector to the service line, depress the lock lever and push on over the tubing, until the spring loaded seat and plunger assembly is depressed a minimum of 1/8 inch

This self-sealing, automatic locking device works on a push-on pull-off principle. Instantly connects and seals pressure lines

​Standard  TC, RTC, and OTC Connectors are of aluminum construction with a heat  treated and plated steel lock lever. Neoprene seals and packing, suitable for temperatures from -20° to 250° F (-29° to 121° C) are standard, but other seal and and quad ring materials are available. 

R​TC Tube Connectors

​.060" to 3/8" O.D. (2 mm to 9 mm)


The OTC Tube Connector have been designed specifically for use in those applications where there are advantages in making the tube connector's seal on the outside diameter of the tube - for example, where connection had to be made to smooth tubes which do not have square cut ends. They feature "Full Flow" design with an internal tube stop. A seal is compressed around the tube by the plunger as it is actuated by the test pressure. In 1500 Series OTC connectors for capillary tubes, a leak free seal is created by the O-ring which is compressed around the tube by the plunger as it is actuated by the test pressure. A lock lever grips the tube for positive hold.
