Press joining is a form of mechanical connection for copper and steel tubing which uses a press tool, jaws, and rings to affix the sealing element and fitting to the tubing.

 

Press copper joining systems offer a high quality installation that is faster and cleaner than traditional solder. Press copper joining provides a reliable long lasting installation both above and below ground. The tubing should be fully inserted into the fitting, and the press made according to manufactures instructions, using the press tool, jaws and rings recommended by the manufacturer. For applications other than domestic water contact the fitting manufacturer.

 

Press joining for stainless steel pipe provides a fast, easy, clean and reliable means for installing 1/2- 2" (15 - 50mm) stainless steel piping systems. Press joining requires no flame or arcs as with welding; no cutting oil, chips or preparation time as with threading or flanging and is rated to 300 psi (2065 kPa) or ANSI Class 150 systems (except steam). Pipe is cut to size, inserted into the coupling and the coupling pressed onto the pipe in seconds. The system is approved by the American Bureau of Shipping (ABS) for all water services including fire protection. It meets the hanging requirements of ASME B31.1, B31.3 and B31.9. Type 316/316L Pressfit couplings, fittings and approved pipe are UL classified in accordance with ANSI/NSF 61 for cold +86°F (+30°C) and hot +180°F (+82°C) potable water service.
