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).

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.

Ultra-Chemical-Resistant Food Industry
Compressible PTFE Pipe Gaskets with Bolt Holes
Made of FDA-listed material for use with food and beverage, these soft expanded PTFE gaskets compress to ensure a tight seal. They are chemically inert (except to molten alkali metal and fluorine compounds). Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. All gasket specifications are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

Ultra-Chemical-Resistant Food Industry Compressible PTFE Pipe Gaskets
These soft expanded PTFE gaskets are made of FDA-listed material for use with food and beverage. They are chemically inert (except to molten alkali metal and fluorine compounds) and are compressible to ensure a tight seal. Also known as ring gaskets, use them with raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. All gasket specifications are sized to meet ANSI standards. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.
