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.

Temperature Range: 35° to 140° F
Tubing: See table
Specifications Met: See table

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.

Fittings with UNS threads are also known as faucet connectors; they attach directly to a faucet threaded inlet or water line.

NPTF (Dryseal) threads are compatible with NPT threads.

Barbed Hose Fittings for Food and Beverage

These fittings are FDA compliant, so they’re suitable for food and beverage applications and won’t impart tastes or odors to the product. Secure barbed ends into plastic or rubber hose with a clamp. These fittings are lightweight with good corrosion resistance.

Adapters are also known as hose nipples. They adapt a barbed end to a threaded end.

Polypropylene fittings meet NSF/ANSI 61 safety standards for use with drinking water systems.

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.

Plugs with male threaded end are also known as F adapters.

Plugs with female threaded end are also known as A adapters.

Plugs with barbed end are also known as E adapters. Insert the barbed end into rubber hose and secure with a clamp.

Sockets with male threaded end are also known as B couplers.

Sockets with female threaded end are also known as D couplers.

Sockets with barbed end are also known as C couplers. Insert the barbed end into hose and secure with a clamp.

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.
