3/8 Bonded Washer 18-8 SS . Where sealing properties are required, the conical design directs the flow of the elastomeric portion toward the problem areas. Where cushioning or vibration presents a problem, our full-face elastomeric material affords 100% protection.
Features Include: Quality elastomeric compounding to meet specifications for elasticity, memory, temperature extremes, chemical, ozone, and sunlight-resistance. Conical design directs flow of facing materials to form a seal conforming to both fastener and sealing surface. Full-face design cushions fragile surfaces and minimizes vibration.
