Metal cam-and-groove couplings have better durability than plastic cam-and-groove couplings.

Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into hose and secure with a clamp or a crimp-on hose ferrule.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

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.

Fittings meet NSF/ANSI Standard 61 for drinking water. Attach them to garden hose for a variety of water supply applications. They are metal for better durability than plastic garden hose fittings.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

Fittings can withstand temperatures up to 200° F.

Connect drinking water lines with ease—these one-piece fittings have a built-in sleeve that crimps onto tubing for a leak-tight connection that doesn’t require heat or soldering. These fittings meet NSF/ANSI 61 for drinking water systems and are compatible with Viega PEX tubing.
