What is the operating pressure of a press-connect?

Advances in press-connect and O-ring/gasket material technology are now such that press-connect joining is being utilized for high pressure HVACR applications rated up to 700 psi operating pressure (see Table 14.4b ).

What is crimp configuration?

In many cases, the geometry of the crimp configuration is similar to that for standard, low-pressure press-connect fittings. Though these may require specially designed jaws to accommodate slight changes in geometry or fitting thickness, the installation steps are essentially the same as those shown in the previous section.

Can crimping jaws be interchangeable?

These fittings, tools and crimping jaws are not interchangeable with standard low-pressure press-connect systems, so care should be taken to ensure that only the proper, compatible fittings, press jaws and tools are used. Always refer to the manufacturers’ installation instructions.
