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).

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-Pressure Compression Fittings for Stainless Steel Tubing
- Tubing: Use with seamless 304 or 316/316L/316Ti stainless steel that meets DIN EN 10216-5 or DIN EN 10305-1
- Specifications Met: DIN 2353, ISO 8434
The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings. A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Made from 316 stainless steel, these fittings won’t corrode from water, chemicals, or salt spray. They are also known as flareless fittings. They meet ISO 8434 (formerly DIN 2353), an international standard for tube fitting dimensions and materials.

- Tubing: Use with seamless steel
- Specifications Met: SAE J514
Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°. Sleeves are zinc-plated steel for fair corrosion resistance. They are also known as ferrules.
Inch × metric sleeve adapters convert the fitting from inch to metric.

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
- 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.
