The strongest steel fittings we offer, these can withstand extreme-pressure applications.

Suitable for use in fire-protection applications, these pipe fittings are made of cast iron, so they are brittle and can be quickly opened with the strike of a sledge hammer.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

A galvanized finish gives these fittings better corrosion resistance than our plain steel high-pressure fittings. Also known as Pressure Class 3000 fittings.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

FM-approved for fire protection applications, these flanges are cast iron, so they're brittle and can be quickly opened by hitting them with a sledge hammer.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slide the pipe into the socket and weld.

Also known as Pressure Class 6000 fittings, these heavy duty forged fittings are the strongest steel fittings we offer.

Use these corrosion-resistant fittings in a low-pressure pipe line.

The male threads on these fittings have a sealant applied for extra leak protection.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

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

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

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

Often used in kilns and other heating equipment, these sights have a quartz window that can withstand temperatures up to 1600° F. They're also known as peep sights.
