How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Easy-Access UV-Resistant Polypropylene
Pipe Fittings for Chemicals
- For Use With:
Fittings: Acetic Acid (5%), Calcium Chloride, Hydrochloric Acid (10%), Phosphoric Acid (85%), Salt Water, Sodium Hydroxide, Sulfuric Acid (30%), Water
Gaskets: See Gaskets - Temperature Range:
Fittings: 0° to 150° F
Gaskets: See Gaskets
Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Connect the flanged end to another quick-clamp fitting with a clamp and a gasket (all sold separately). Fittings are polypropylene, which resists a wide variety of acids, solvents, and other harsh chemicals. The fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.
Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

To prevent leaks in threaded connections, apply a non-hardening, plastic-compatible sealant to the male threads. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- Temperature Range: See Gaskets or O-Rings
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 or O-ring, 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 or O-ring material you choose.
Inch fittings connect to another same-sized fitting and squeeze the gasket in between for a tight seal.
304 stainless steel fittings have very good corrosion resistance. 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 or O-ring (all sold separately).

- For Use With: Air, Beverage, Dairy, Food, Water
- Tubing: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM 270
- Specifications Met: 3-A Certified 63-04
Fittings with butt-weld end are also known as ferrules; they weld to tubing for a permanent, flush connection.

The temperature rating of the fitting will vary depending on the gasket or O-ring material you choose. Buna-N gaskets are oil resistant. EPDM gaskets or O-rings resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets or O-rings stand up to fuel, oil, and acid condensates. PTFE gaskets or O-rings withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.

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. 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 bottle or bag.
Tube fittings with quick-clamp connections are easy to take apart for cleaning or reconfiguring your line.
