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.
316 stainless steel fittings have excellent corrosion resistance.
Fittings that meet DIN standards adhere to international requirements for sanitary quick-clamp fittings.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

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. Double-bolt clamps meet ASME design standards for pressure vessels.
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.
