Use these barbed pipe fittings in residential and commercial plumbing and water supply applications up to 60 psi. Also known as insert fittings, they have a barbed end that slides into semi-flexible plastic pipe and secures with a clamp (sold separately). Since you don't have to wait for cement to dry, they're quicker to install than socket-connect fittings. Fittings are plastic for good corrosion resistance. They meet ASTM D2609 specifications for barb dimensions.

Polypropylene fittings have better flexibility than nylon fittings, so they can accommodate movement and vibration in your line without cracking. They also have better moisture resistance than nylon, so they won't soften and lose strength over time. Nylon fittings have better impact and abrasion resistance than polypropylene fittings, but can soften when exposed to moisture.

Note: Barbed pipe fittings are measured by pipe size, which is not an actual measured size, but rather an industry designation.

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.
