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

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

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

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.

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

Made to tighter tolerances than other steel pipe fittings, these are also known as instrumentation fittings.

To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Connect to CPVC pipe for use in high-temperature plumbing and water supply applications.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°.

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.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.
