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.

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. 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 A-Lok fittings.

316 stainless steel fittings have excellent corrosion resistance.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings

Temperature Range: See Gaskets

The smooth finish inside these fittings makes it easy to remove product residue. Also known as aseptic and tri-clamp fittings, they connect with a gasket, a clamp, and another quick-clamp fitting for a fast and easy way to access your line. The pressure rating of the fitting will vary depending on the clamp you choose, and the temperature rating will vary based on the gasket material you choose.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Fittings that meet DIN standards adhere to international requirements for sanitary quick-clamp fittings. 3-A certified fittings comply with sanitary standards.

Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Solder-Connect Fittings for Copper Tubing

Temperature Range: 32° to 200° F

Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61, EN 1057, or DVGW GW 8(P).

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

High-Pressure Compression Fittings for Steel Tubing

For Use With: Hydraulic Fluid
Specifications Met: DIN 2353, ISO 8434

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications. Their single sleeve, or ferrule, bites into tubing as you tighten the nut, creating a seal that is leak tight even at high heat. The nut and sleeve are included. All meet ISO 8434 (formerly DIN 2353), which is an international standard for tube fitting pressures.

Nickel-Plated Brass Push-to-Connect Tube Fittings for Air

For Use With: Air, Lubricated Air
Temperature Range: 0° to 140° F, except plugs and straight connectors are 32° to 140° F
Tubing: Fittings with Release Ring and Fittings with no Release Type: Use with firm or hard (Durometer 95A-60D) nylon plastic, polyethylene plastic or polyurethane rubber
Fittings with Release Sleeve: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring or sleeve and pull the tubing out of the fitting.

Fittings with release sleeve are easier to disconnect than fittings with a release ring because they are seamless and won't collect dirt and debris.

Fittings with thread sealant offer extra protection against leaks.

Moisture-Resistant Push-to-Connect Tube Fittings for Air and Water

For Use With: Air, Lubricated Air, Water,
except Manifolds with Swivel: Air, Water
Temperature Range: 32° to 100° F
Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. They have good corrosion resistance.

Nickel-plated brass fittings have better corrosion resistance than unfinished brass fittings.

Fittings with thread sealant offer extra protection against leaks.

Universal-Thread Moisture-Resistant Push-to-Connect Tube Fittings for Air and Water

Male
Threads
with Gasket

Temperature Range: 32° to 100° F
Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber

The threads on these fittings mate with NPT, NPTF (Dryseal), BSPT, and BSPP threads. The male threads have a gasket to protect against leaks. Fittings are moisture and corrosion resistant, so they’re good for water and humid air applications. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting.

Brass Compression Tube Fittings for Air and Water

For Use With: Air, Lubricated Air, Water
Temperature Range: See table
Tubing: Use with firm or hard (Durometer 95A-Rockwell R110) nylon plastic, polyethylene plastic, polypropylene plastic or polyurethane rubber
Specifications Met: SAE J512, except metric sizes

A single sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. They are brass for good corrosion resistance.

Tube supports (sold separately) are recommended if you want to use the fittings with soft polypropylene and polyethylene tubing to prevent the tube from collapsing.

Install plugs with a nut (sold separately) on the end of fittings to block the flow of air or water.

BSPP male threads have an O-ring to protect against leaks.
