Performance Advantage

  • NEMA 250 Type 6P performance rated (Neoprene Version)
  • Low-torque washer for fastening requirements under 100 inch-pounds
  • Exceptional performance in high-pressure sealing applications
  • Applying torque forces the flat surface of the washer to conform to the underside of the fastener resulting in metal-to-metal contact and an air & water-tight seal

Sealants

Neoprene

  • Stable, non-aging sealant
  • Temperature range: -80°F to 300°F
    (-62°C to 148°C)
  • Chemically resistant to water, gasoline, petroleum oils, salt sprays, alkali, some acids, organic and aromatic solvents, detergents, ozone, hydrocarbons, oxygenated and chlorinated solvents

Viton®

  • High performance elastomer providing excellent stability
  • Temperature range: -10°F to 400°F
    (-23°C to 204°C)
  • Resistant to diesel fuels, oils, chemicals, most mineral acids, compression set, mold, fungus, and many aliphatic and aromatic hydrocarbon fluids that act as solvents for other rubbers
  • Exceptional resistance to atmospheric oxidation, uv light, and weathering
  • Low burning characteristics: inherently more resistant to burning that other non-fluorinated hydrocarbon rubbers
