Professional Applications & Engineering Value

Engineered for demanding industrial environments, these Santoprene rubber flat washers deliver critical performance advantages where conventional washers fail. The Durometer 64A hardness provides optimal compression and recovery, creating reliable seals in plumbing, automotive, and machinery applications. The beige Santoprene material offers exceptional resistance to chemicals, oils, and weathering while maintaining flexibility across the extreme temperature range from -40°F to 270°F. This combination solves common engineering challenges including vibration-induced loosening, thermal expansion mismatches, and chemical degradation. The precise 1/2" inner diameter and 1.062" outer diameter ensure proper fitment with standard fasteners while the controlled thickness provides consistent sealing pressure distribution.
