At A.S.A.P we supply a large range of hose fittings and pipe connections for all plumbing applications. Fittings are available in brass, DZR brass, bronze, stainless steel and plastic constructions. We offer many different kinds of pipe fittings, including: adaptors, blanking caps, bulkhead fittings, bushes, calorifier fittings, couplings, cross fittings, elbows, hose connectors, hose tails, hydraulic fittings, nipples, nuts, olives, pipe manifolds, plugs, scoops, scuppers, sender adaptors, skin fittings, sockets, stop ends, T pieces, unions, washers and Y pieces. These can be filtered by composition for your convenience, bearing in mind that all through hull fittings should be correctly electrically bonded to protect your fittings from electrolytic corrosion. It is also important to consider materials when installing fittings below the waterline - brass is susceptible to salt water corrosion in these situations. Below are the specifications of materials we use in our marine fittings:
