SharkBite Max push-to-connect fittings allow you make pipe connections with half the insertion effort while withstanding double the burst pressure. Featuring a newly designed stainless-steel retainer, SharkBite Max delivers additional strength and durability while providing a 250 psi pressure rating. Slip couplings are the most efficient way to repair a burst pipe or leak. A slip fitting does the job of two couplings and extra pipe. Only one end of the coupling has a stop, allowing the opposite end to slide freely over the end of a pipe. The fittings are then released using a disconnect tool and slide back onto the other end of the pipe for a successful connection and leak repair. Disconnected Clip is included with the fitting. UPC, IAPMO, and NSF-61 certified and approved. The fitting should be used with copper only and is rated at 200 F, 250 psi. It is made of 1-piece DZR brass.
