Compression couplings are used to join conveying tube and bends. They offer easy installation and secure joints by mechanically locking the tube. This is as simple as tightening the clamping bolts which are attached. The couplings come complete with a white nitrile rubber gasket and stainless steel earth strap. Sizes range from 38mm to 355mm outside diameter and can be supplied in Zinc coated steel, stainless steel or aluminium. For extra clamping, up to 5 bolts can be supplied to each coupling. Various gasket material options are also available including black neoprene, red rubber, silicone, EPDM and viton. Stainless steel gasket protectors are also available when conveying abrasive products.
