Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line.

Wing nut—These clamps tighten by hand, no tools required. Clamps with a spring closure can be installed with one hand, as the spring holds the clamp in place. Clamps with a safety wing nut have a wider wing nut base and a narrower clamp gate than our other wing nut clamps, so they stay latched even when bumped and knocked. This is useful in steam lines where accidentally releasing the clamp could cause injuries. They also have a leak-before-burst design, so rather than bursting dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.

Bolt—These clamps handle higher pressures than wing-nut and lever clamps for a stronger, more secure hold. Tighten them with a wrench.

Recessed nut—These clamps are tamper resistant to reduce the risk of product contamination. A hex socket adapter is required to loosen the nut. They have a leak-before-burst design, so rather than burst dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.

Clamps with a hole for a lockout help you comply with Hazard Analysis and Critical Control Point (HACCP) programs and Good Management Practices (GMP).

Clamps with a two-pin hinge require less clearance to open than other clamps. Use these for installation in tight spaces.

304 stainless steel clamps have very good corrosion resistance. 316 stainless steel clamps are more corrosion resistant than 304 stainless steel clamps. Nylon clamps are lightweight compared to stainless steel clamps.

Clamps that meet DIN 11864 or DIN 32676 adhere to international standards for sanitary quick-clamp fittings.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings or bite fittings. Use them in low- to medium-pressure applications.

316 stainless steel fittings have excellent corrosion resistance.

ISO and DIN fittings meet international dimensional standards.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps. However, rubber sleeves can’t withstand temperatures as high as metal ones. To create the strong seal, tighten the included nut. These fittings are made of 316 stainless steel, so they have excellent corrosion resistance. They’re also known as flareless fittings. All meet DIN 3861, which is an international standard for compression tube fitting specifications.

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 or EN 1057.

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

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings. They have a single sleeve (ferrule) made of plain brass that gently bites into copper tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. These fittings are also known as flareless fittings. All meet DIN standards for tube fitting dimensions.

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. Fittings are zinc-plated steel for fair corrosion resistance. They are compatible with Swagelok®, Let-Lok, and A-Lok fittings.

Use these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on steel tubing. They are also known as ferrules.

Zinc-plated steel sleeves have fair corrosion resistance. 316 stainless steel sleeves have excellent corrosion resistance.

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.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect fittings with a release ring, push on the release ring and pull the tubing out of the fitting.

Polypropylene fittings have excellent impact and abrasion resistance. They meet NSF/ANSI standards for safe use with food. Some are also FDA compliant for indirect contact with food.
