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.

Press-Connect Fittings for Drinking Water

Maximum Pressure: 160 psi @ 72° F
Temperature Range: -30° to 180° F
Tubing: Use with hard polyethylene plastic or copper
Specifications Met: IAPMO Listed, NSF/ANSI 61

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. Each fitting has a viewing hole to prevent installation errors and ensure it’s fully inserted before installing them. Press them onto polyethylene tubing, also known as Viega PEX tubing, using a crimping tool (sold separately). Choose a crimping tool with a grip color that’s the same as your fitting’s ring color. They meet NSF/ANSI 61 for drinking water systems.

Fittings are IAPMO (International Association for Plumbing and Mechanical Officials) certified to comply with product performance standards. They also comply with the UPC (Uniform Plumbing Code) for installation and repair of plumbing systems.

Bronze fittings are strong and resist corrosion.

Press-Connect Fittings for Copper Tubing

For Use With: Drinking Water
Maximum Pressure: Fittings compatible with Viega ProPress or Viega ProPress XL-C: 200 psi @ 72° F
Fittings compatible with Viega Pex or Viega PureFlow Press: 100 psi @ 72° F
Temperature Range: 0° to 250° F
Tubing: Fittings compatible with Viega ProPress or Viega ProPress XL-C: Use with K, M, L copper
Fittings compatible with Viega Pex or Viega PureFlow Press: Use with hard polyethylene plastic
Specifications Met: See table

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.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Inline Tee Adapters, Female Press-Connect Tube × Female Threaded Pipe

Inline tees are also known as branch tees. Use inline tee adapters to add lines or components, such as gauges, without additional fittings.
