How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Threaded Standoff Caps

Give open-ended standoffs a finished look and protect them from dirt and debris.

Tire Valve Caps

Keep dust and debris out of your tire valve.

Brass and Bronze Threaded Pipe and Pipe Fittings

Precision Extreme-Pressure
Brass Threaded Pipe Fittings

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

High-Pressure Brass Threaded
Pipe Fittings for Drinking Water

Use these heavy-duty brass fittings for high-pressure drinking water applications.

Low-Pressure Chrome-Plated
Brass Threaded Pipe Fittings

The polished chrome plating not only has a shiny appearance, but also improves corrosion resistance on these Class 125 fittings.

Medium-Pressure Brass and
Bronze Threaded Pipe Fittings

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

Low-Pressure Brass and
Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

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.

Low-Pressure Brass Threaded
Pipe Fittings with Sealant

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Class 125 fittings, they are built for use in low-pressure applications.

High-Pressure Brass Threaded
Pipe Fittings with Sealant

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

High-Pressure Brass
Threaded Pipe Fittings

These brass fittings have the strength to handle high-pressure applications.

Extreme-Pressure Brass
Threaded Pipe Fittings

Extreme pressures are no problem for these heavy-duty brass fittings.

Miniature Low-Pressure
Brass Threaded Pipe Fittings

Less than an inch in length, these miniature fittings work well in low-pressure pipe lines that are tight on space.

Brass and Bronze Unthreaded Pipe Flanges

Brass and Bronze
Unthreaded Pipe Flanges

Bolt these flanges to another same-size flange with a gasket to create an access point within a pipe line. They are also known as Silbraze flanges.

Hose Fittings

Threaded Hose Fittings
for Compressed Gas

Use these CGA fittings to connect welding hose to pressure regulators and torches.

Metal Garden Hose Fittings

Attach these fittings to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

Rocker-Lug Fire
Hydrant Caps and Plugs

Thread these caps and plugs onto fire hydrants and washdown equipment to close off the line. They have rocker lugs for easy gripping.

Metal Cam-and-Groove
Hose Couplings for Water

Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.
