About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

High-Pressure Plated Brass Threaded Pipe Fittings

The plating on these brass fittings creates a shiny finish and provides extra protection in corrosive environments. Fittings have the strength to handle high-pressure applications.

Nickel-plated brass fittings provide better corrosion resistance than unplated brass fittings.

Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through a wall or panel to create an inlet or outlet.

Through-Wall Bushing Straight Reducing Adapters

For Use With: Air, Natural Gas, Oil, Water

Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these fittings in a low-pressure pipe line. 304 stainless steel fittings have very good corrosion resistance.
