Water Truck Plumbing

UnitedBuilt offers a wide range of water truck plumbing components designed for reliable fluid handling in demanding applications. Our selection includes pipe fittings, couplings, adapters, hose fittings, and sealing components used in water trucks, construction equipment, and industrial systems.

We stock a variety of weld fittings in schedule 40 black steel and stainless steel, along with multiple connection types including weld (plain), grooved, female NPT, male NPT, and notch connections. Our lineup also includes OEM Victaulic grooved fittings, such as couplings, tees, elbows (45° and 90°), reducers, caps, and flanges.

In addition, we carry threaded pipe nipples, pipe adapters, cam & groove fittings, swivel joints, and hose fittings including king nipples, hose barbs, and clamps. Supporting components such as gaskets and thread sealants are also available to ensure secure, leak-free connections.

These plumbing components are built for durability and compatibility across a wide range of systems, helping ensure efficient fluid transfer and long service life in real-world conditions.

We work to keep these products readily available and offer fast shipping to help minimize downtime and keep your equipment running.
