** 1\" Stainless Steel Press Sleeve
The Press Sleeve slides over the outer part of the PEX-a tubing, before inserting the fitting. When the fitting is in place, the press tool secures the connection in one single press, evidenced by a smooth visible W depression ring on the sleeve's surface. No crimp gauge is required with a Press Sleeve, thus eliminating a step in the whole installation procedure. Once the pressing is complete, everything is set for the pressure test.
