Working Pressure:

1. Ground Joint: extra wide seating surface.
   
   
2. Brass Ring: serves as bearing surface for the nut. Eliminates possibility of damage to nylon insulation when making-up.
   
   
3. Precise Mating Tapers: provides high compression, gas-tight seal. Will not loosen under strain or vibration.
   
   
4. Forged Steele Nut and Body: made from hot-forged AISI 1023 open hearth, silicon killed forged steel.
   
   
5. Extra Heavy Shoulder: on swivel end and in the nut. Increases strength to withstand pipe strains, vibration, misaligned connections, and wrench abuse.
   
   
6. Internal one-piece construction: insulation is bonded and molded to metal body. No loose parts to assemble, lose or misalign during field installation.
   
   
7. Precision Threading: expert machining for exact dimensions.
   
   
8. 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 250° F. Georg Fischer Central Plastic’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.
