Couplings

The Bolted Couplings are for all lines carrying dry materials. They can be easy to install. They are usually galvanized or stainless steel shells. They are precision cut on the inner sleeves and gaskets, their gaskets are up to the neoprene standard. They are an economical, reliable method of connecting conveying lines. Constructed in a choice of galvanized steel or stainless steel, these couplings offer dependable service. A thick 1/8 in. gasket is available in black neoprene or white nitrile (food grade) as stock items. Other gaskets are available. Grade 5 bolts resist stripping and flat washers make tightening simple. Bolt type couplings are available to join PE to PE or to other types of pipe such as PVC, steel and cast iron, in sizes from 1¼” IPS and larger. These couplings compress an elastomeric gasket around each pipe end to be joined, to form a seal and may incorporate a grip ring that provides pullout resistance, possibly exceeding the yield strength of the PE pipe.
