Push to connect fittings have grown in popularity due to their ability to efficiently couple fittings to thermoplastic tubing while maintaining performance. Invented in 1969, push-to-connect fittings were first used for industrial pneumatic applications, typically at the point-of-use.
In 1997, that technology was applied to compressed air aluminum piping, creating the Transair® product line. The connection technology of Transair changes as the diameter size increases.
Push-to-connect is used for 1/2" to 1-1/2" pipe
Snap ring is used for 2" to 2-1/2" pipe
Clamshell for 3" to 6"
Out of the three connection technologies, push-to-connect is the easiest to install but oftentimes causes the most confusion.
By following these simple steps, you will be an expert installer of Transair® push-to-connect fittings. (Full lengths of Transair pipe only require three installation steps, while cut lengths require seven steps.)
Every Transair connector comes pre-torqued from the factory. This is represented by solid and outlined arrows on the nuts aligned within a corresponding torque range on the body of the connector. This torque guarantees the safety and seal strength of each connection.
Push the pipe into the connector until the mark meets or is covered by the nut of the connector.
All 1/2" (16,5mm), 1" (25mm), 1-1/2" (40mm) pipes come from the factory with the insertion depth pre-marked on both ends.
DO NOT tighten the connector after the pipe has been inserted. The connectors are pre-torqued and do not require additional tightening.
To ensure the proper stability of the system, we recommend the use of at least two (2) clips per pipe.
Maximum of 5 feet of space between clips for 9 feet lengths of pipe
Maximum of 10 feet of space between clips for 15 and 20-foot lengths of pipe
Transair can also be cut to length to fit the installation area. Follow these below steps to ensure the proper installation of cut pipes.
Every Transair connector comes pre-torqued from the factory. This is represented by solid and outlined arrows on the nuts aligned within a corresponding torque range on the body of the connector. This torque guarantees the safety and seal strength of each connection.
Place the pipe cutter (6698 03 01) on the pipe at the desired cutting mark. Rotate the pipe cutter around the pipe until the pipe is cut.
Carefully chamfer the outer edge of the pipe using the chamfer tool (6698 04 01). Then, deburr the inner edge of the pipe using the deburring tool (6698 04 02)
Using the Transair (6698 04 03) marking tool, mark the insertion depth on the cut end of the pipe.
Push the pipe into the connector until the mark meets or is covered by the nut of the connector.
To ensure the proper stability of the system, we recommend the use of at least two (2) clips per pipe.
