Female x female for iron pipe sizes 1/2", 3/4", 1", 1-1/4 ", 1-1/2", 2"
The finest insulating union ever designed!
Ground Joint - Extra wide seating surface.
Precise Mating Tapers - Provides high compression, gas-tight seal. Will not loosen under strain or vibration.
Nut and Body - Made of high test, air refined malleable iron.
Extra Heavy Shoulder - On swivel end and in the nut. Increases strength to withstand pipe strains, vibration, misaligned connections, and wrench abuse.
Integral One-Piece Construction - Insulation is bonded and molded to metal body. No loose parts to assemble, lose, or misalign during field installation.
Precision Threading - Expert machining for exact dimensions. Meets ANSI B2.1.
Molded Nylon - Non-brittle to withstand extreme shock loads and impact without fracturing. Chemically unaffected by most substances including gas, water, ammonia, petroleum oils, and greases at temperatures as high as 250oF. Centrals insulation design uses a return of nylon on the internal surface, which gives additional protection against shorts caused by bridging of foreign materials. Dielectric strength goes far beyond the toughest requirements.
