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.

Metal Barbed Hose Fittings for Air and Water
Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.
Bronze fittings have better corrosion resistance and are stronger than brass and aluminum fittings. A pipe thread sealant is recommended to seal bronze fittings with BSPP male threads, which is unlike other materials that can often use a gasket.
Fittings with a threaded end are also known as hose nipples.

Barbed Tube Fittings for Drinking Water
- Temperature Range: 32° to 180° F
- Tubing:
All Fittings: Use with hard polyethylene plastic
Socket-Connect Fittings: Use with hard polyethylene plastic or copper - Specifications Met: See table
Connect these fittings to tubing with a ring and a crimping tool (both sold separately). They have multiple barbs that grip onto tubing for a secure hold. Fittings are compatible with Viega PEX tubing. Safe to use with drinking water, these fittings meet the strict standards of NSF/ANSI 61.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
For technical drawings and 3-D models, click on a part number.
Use a press-connect crimping tool to secure the press-connect end to tubing or the male socket-connect tube end of a fitting without heat or soldering. They have an internal O-ring that creates a leak-tight connection.
