Medium-Pressure Brass and Bronze Threaded Pipe Fittings
Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings. They offer good corrosion resistance.
Fittings with intermittent swivel rotate 360° as needed to allow movement in a rigid metal piping system.

Bronze Unthreaded Pipe Fittings
Snap a brazing ring (sold separately) into these fittings and braze them to unthreaded pipe for a strong, leak-resistant connection. Fittings are also known as Silbraze fittings. They are bronze, which is compatible with brass and has good corrosion resistance.

Solder-Connect Fittings for Copper Tubing
- Temperature Range: 32° to 200° F
Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61 or EN 1057.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Crimp these fittings to copper tubing with a crimping tool (sold separately). An O-ring on the inside of the fitting creates a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings. Fittings have good corrosion resistance. They meet NSF/ANSI safety standards for use with drinking water systems.

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.
