O2PT-1X3/4F Henry Flange Union, Female Pipe Thread - Oval 2 Bolt Flanges 3/4" FPT Female Flange

Flange Unions offer a convenient method for connecting pipe and installing shut-off valves with identical groove patterns.

Applications:

Flange Unions are a practical alternative to weld or screw end connections. Where shut-off valves are used in conjunction with the flanges the valves may be replaced without performing any cutting operations. NPT and Socket Weld Flanges are suitable for use with ammonia, HCFC and HFC refrigerants and their associated oils, as well as other industrial fluids noncorrosive to steel and Garlock #2930. Lead gaskets are also available for two bolt NPT and Socket Weld Flanges for chlorine service.

ODS Flanges are suitable for use with HCFC and HFC refrigerants and their associated oils, as well as other industrial fluids non-corrosive to steel, copper and Garlock #2930
