INSULATED PRODUCTS FOR CATHODIC PROTECTION – MILLIONS IN SERVICE Stops galvanic and electrolytic corrosion of mains and services. Permanent, economical protection.Protects against stray or induced house currents.  


Working Pressure:

  1. Ground Joint: extra wide seating surface.
  2. Precise Mating Tapers: provides high compression, gas-tight seal. Will not loosen under strain or vibration.

  3. Nut and Body: made from high-test, air refined malleable iron.

  4. Extra Heavy Shoulder: on swivel end and the nut. Increases strength to withstand pipe strains, vibrations, misaligned connections, and wrench abuse.

  5. Integral One-Piece Construction: nylon insulation is bonded and molded on to metal body. No loose parts to assemble, lose or misalign during field installation.

  6. Precision Threading: expert machining for exact dimensions. Meets ANSI B2.1.

  7. 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 Plastics 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.
