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

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

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 heavy duty forged flanges for high-pressure applications.

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

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.

Typically used with extreme-pressure stainless steel unthreaded pipe fittings.

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

Use these fittings for low-pressure applications in noncorrosive environments.

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

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.

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

Forged for extra strength, these heavy duty unthreaded flanges can withstand high-pressure applications.

For excellent strength in extreme-pressure applications, choose these heavy duty Pressure Class 1500 flanges.

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

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.

Typically used with standard-wall aluminum unthreaded pipe fittings.

Also known as Schedule 40 fittings, these have thicker walls than our thin-wall aluminum unthreaded pipe fittings.

Thick walls give these Schedule 80 fittings excellent strength.

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.

Also known as Pressure Class 200 fittings.

Use at pressures up to 4,300 psi.

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

Also known as I-line fittings, these quick-clamp fittings permit easy access to your line.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.
