Low-Pressure Brass and Bronze Threaded Pipe Flanges
- For Use With: Air, Drinking Water, Natural Gas, Oil, Steam, Water
- Pressure Class: 150
- Specifications Met:
NPT: ASME B1.20.1, ASME B16.24, ASTM B584, NSF/ANSI 61
BSPT: ASTM B584, BS21 - Pipe Nipples and Pipe: Use Schedule 40 brass
- Fittings:
NPT: Use Class 125 brass
BSPT: Use Class 125 bronze
Also known as Pressure Class 150 flanges, these are designed for low-pressure applications. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges have good corrosion resistance. To adhere to safety standards for drinking water systems, use flanges that meet NSF/ANSI 61.

Press-Connect Fittings for Copper Tubing
- For Use With: Drinking Water
- Maximum Pressure: 200psi @ 72° F
- Temperature Range: 0° to 250° F
- Tubing: Use with K, M, L copper
- 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.
Straight adapters with flanged end bolt to equipment or other flanged connections found on pumps and valves to create a convenient access point.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
