Silver ions in the material help inhibit the growth of bacteria, mold, fungi, and other odor-causing microbes.

Fittings have good corrosion resistance.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Made of brass, these fittings have good corrosion resistance.

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

Use at pressures up to 250 psi.

An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

Withstanding temperatures up to 300° F, these fittings have the highest temperature rating of all our push-to-connect tube fittings for air and water.

Lighter in weight than their metal counterparts, these compression fittings are polypropylene.

The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings.

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.
