Yor-Lok Fittings for Stainless Steel Tubing

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).

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.

Universal-Thread Nickel-Plated Brass Push-to-Connect Tube Fittings for Air and Water


Threads
with Gasket
- Temperature Range: 0° to 175° F
- Tubing: Use with firm (Durometer 85A-100A) nylon plastic or polyurethane rubber
- Specifications Met: ISO 14743
Made of nickel-plated brass, these tube fittings resist corrosion better than plain brass fittings. The male threaded ends connect to NPT, NPTF, BSPP, BSPT, and other universal threads, so you don’t have to bother matching exact thread types. They also have a reusable gasket to protect against leaks. The tube ends connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect them, push the release ring and pull the tubing out of the fitting. These fittings are sometimes called instant fittings. All meet ISO 14743, which is an international standard for push-to-connect fittings for plastic tubing.

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.

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 1A-95A or Rockwell 15T 1-15T 60) 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.
