- Ground Joint - Extra wide seating surface.
- Brass Ring - Serves as bearing surface for
the nut. Eliminates possibility of damage to nylon insulation when making up.
- Precise Mating Tapers - Provides high
compression, gas-tight seal. Will not loosen under strain or vibration.
- Forges Steel 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.
- 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. Central's 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.
