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. 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).

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. Also known as ultra-high-purity fittings, they’re packed in a Class 100 clean room, cleaned, and double bagged. They are commonly used in semiconductor applications. Fittings use a metal gasket (sold separately), which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Fittings are 316 stainless steel for excellent corrosion resistance.
To assemble, place a gasket between the gasket ends before gently rotating the female-threaded fitting onto the male-threaded fitting. Tighten until 1/8 of a turn past finger tight.
Choose threaded fittings to attach directly to other fittings. Or, choose one of the following types of fittings to attach directly to tubing:
Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.
Socket-connect fittings are easier to weld than butt-weld fittings because they don’t need to align perfectly.
Yor-Lok fittings have two sleeves that bite into tubing as you tighten the nut, creating a strong steal without the need for welding. They're also known as instrumentation fittings.
Tube stem fittings connect to Yor-Lok fittings (sold separately).

Retaining
Tabs
Nickel gaskets are softer than stainless steel gaskets, so they won’t wear down sealing surfaces as much, and they’re easier to tighten. They’re reactive to carbon monoxide and ozone, so they shouldn’t be used with those chemicals.
Hard and heat resistant, stainless steel gaskets can be used in a wider range of applications than nickel gaskets such as carbon monoxide and ozone. However, they’re harder to tighten than nickel gaskets, and they’ll wear down sealing surfaces more quickly.
Silver-plated stainless steel gaskets are softer than unfinished stainless steel gaskets, so they won’t wear down sealing surfaces as much, and they’re easier to tighten. However, they oxidize when exposed to air, and silver particles might flake off during assembly.
Gaskets with retaining tabs stay in place during installation, so you don’t have to hold the gasket while fastening fittings together. This also means they’re less likely to scratch or nick your fittings by rotating during installation.

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.
