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

Low-Pressure Brass and Bronze Threaded Pipe Fittings

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

Low-Pressure Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Medium-Pressure Plated Brass Threaded Pipe Fittings

Plated with nickel, these brass fittings resist rust better than steel and unfinished brass fittings. Select them when you need more strength in corrosive environments to handle higher pressures than our low-pressure fittings.

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.

High-Pressure Brass Threaded
Pipe Fittings for Drinking Water

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

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.

High-Pressure Brass Threaded Pipe Fittings

These brass 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.

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.

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.

Wire, Cable, and Hose Routing & Protecting

Submersible Threaded Breather Vents

Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.

Vented Brass Submersible Cord Grips

Secure cable installed through enclosures in wet environments while venting air to protect electronics from condensation.

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.
