Professional Applications & Engineering Value

These PTFE plastic flat washers deliver critical engineering solutions where standard washers fail. The PTFE material provides exceptional chemical resistance against aggressive solvents, acids, and bases, making them ideal for chemical processing equipment, laboratory instruments, and pharmaceutical applications. Their ability to maintain structural integrity at temperatures up to 500°F solves thermal degradation problems in automotive, aerospace, and industrial heating systems. The precise 0.15" ID ensures secure fitment on No. 5 screw sizes while the controlled 0.045-0.055" thickness provides consistent load distribution in electrical insulation, plumbing assemblies, and precision machinery. These flat washers serve as reliable barriers in corrosive environments where metal washers would rapidly deteriorate.
