This 4 inch mechanical joint Orion Polypropylene no-hub coupling is quick to install and can be easily removed for plan alterations or future repairs. The lower durometer inner shell combined with the ribbed stainless steel outer shell features a 60 inch-pounds torque setting that helps you take the guesswork out of tightening and ensure a more secure, even-pressure seal around the entire joint.
