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.
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).

Buna-N gaskets are oil resistant. EPDM gaskets resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets stand up to fuel, oil, and acid condensates. PTFE gaskets withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.

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.

Sanitary Sampling Stainless Steel Tube Fittings
- For Use With: Dairy, Beverage, Water, Air, Food
- Tubing: Use with welded 316/316L stainless steel
- Specifications Met: 3-A Certified 63-03
Take samples in sanitary environments—these tube fittings won’t contaminate your lines or force you to pause them. Made of 316L stainless steel, they’ll stand up to harsh cleaners and sanitizers without corroding. They also have polished internal surfaces, minimizing the space where bacteria could grow. With quick-clamp connections, they are easy to take apart for cleaning or reconfiguring your line. All are 3-A certified to meet sanitary design standards, so they’re often used in food and beverage, pharmaceutical, and biotech applications.
All fittings require pierceable lids (sold separately) to draw samples through a hypodermic needle. Each lid is good for seven samples, and each sample leaves a hole mark, so you know when it’s time to unscrew the nut on the tube fitting and swap in a new lid. To help prevent dust and moisture from accumulating on the lid, all tube fittings have a dust cover. These lids are FDA compliant, so they keep contaminants from entering your line and also are approved for direct contact with food if they break off and fall in. Manufactured free of contaminants and allergens, all are BPA-, latex-, and phthalate-free. They’re also TSE/BSE compliant, meaning they’ve never come into contact with any animal products.
Pair these tube fittings with liquid samplers for a sample. They use gravity to draw out liquid through the needle directly into the bag.
