Coupler, Stainless Steel, Tote Connection Size 2", Hose Inside Dia. 3/4

Tote couplings are fittings used with drum or tote valves to provide a closed connection that seals out contaminants from fluids being pumped. They have one end for locking into a compatible valve and suction tube assembly and another end for connecting a dispensing hose. These couplings allow drum pump tubes to remain in place until the tote is empty while allowing the pump to be connected and removed as needed. They're often used on containers of diesel exhaust fluid (DEF) to maintain the purity of the fluid.
