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.

UV-Resistant Polypropylene Pipe Fittings for Chemicals

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. 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.

Schedule 40 fittings have thinner walls than Schedule 80 fittings and are typically used in commercial and residential applications.

Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

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.

Plastic Quick-Turn Tube Couplings for Air and Water

For Use With: Polycarbonate Plastic: Air
Nylon Plastic: Air, Water
Polypropylene Plastic: Water
Temperature Range: Nylon Plastic, Polycarbonate Plastic: -20° to 200° F
Polypropylene Plastic: 35° to 150° F
Tubing: Use with soft (Durometer 40A-65A) PVC plastic or silicone rubber

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings. Also known as luer lock couplings, they consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body for easy installation in tight spaces. Plugs and sockets are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.

Polypropylene plugs and sockets are moisture resistant and won’t absorb water and lose strength, even in high-humidity environments.

Note: For a complete coupling, order a plug and a socket.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect fittings with a release ring, push on the release ring and pull the tubing out of the fitting.

Polypropylene fittings have excellent impact and abrasion resistance. They meet NSF/ANSI standards for safe use with food. Some are also FDA compliant for indirect contact with food.

Black fittings have excellent UV resistance and are suitable for outdoor environments.

Cam-and-Groove Hose Couplings for Food and Beverage

Made of FDA listed materials, these couplings are suitable for food and beverage applications and won’t impart tastes or odors to the product. They also meet NSF/ANSI 61 safety standards for use with drinking water systems. A complete coupling consists of a plug and a socket (both sold separately) that allow you to quickly connect and disconnect medium-to large-diameter hose lines. To connect, insert the plug into the socket and press the levers down. The levers fit snugly into the groove on the plug’s body and force the plug against the gasket to form a tight seal. To disconnect, lift both levers and pull out the plug. Plugs and sockets are polypropylene, which is lightweight with good abrasion and corrosion resistance.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.

Sockets with locking levers prevent accidental disconnection. The locking pins engage automatically when the coupling is connected. Press the locking pins simultaneously to disengage.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.
