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.

Made of moisture-resistant acetal, these fittings won't absorb water and lose strength, even in high-humidity environments. 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. All meet NSF/ANSI 61 for use in drinking water systems.

BSPP male threads have a gasket to protect against leaks.

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.

Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line. Clamps with wing nut tighten by hand. Clamps with safety wing nut won’t release from minor loosening or jostling. They have a leak-before-burst design, which means they’ll leak to relieve pressure if the seal fails instead of bursting and causing a safety hazard.

Clamps with bolt tighten with a wrench. They handle higher pressures than wing-nut clamps for a stronger, more secure hold.

Clamps with recessed nut require a hex socket adapter to loosen the nut, preventing the clamp from tampering and accidental removal. They have a hole for lockout (padlock not included) to block unauthorized access, helping you meet Hazard Analysis and Critical Control Point (HACCP) programs and Good Management Practices (GMP). Both of these security measures reduce the risk of product contamination. These clamps have a leak-before-burst design, so rather than burst dangerously if the seal fails, they’ll safely relieve pressure by dripping instead.

304 stainless steel clamps have very good corrosion resistance.

316 stainless steel clamps are more corrosion resistant than 304 stainless steel clamps. Clamps with two-pin hinge apply more even pressure on gaskets than other clamps, causing less wear and tear on gaskets.

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.

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.
