Professional Applications & Engineering Value

These PTFE plastic flat washers deliver exceptional engineering value in demanding industrial settings where high-temperature resistance and chemical stability are critical. The PTFE material maintains its structural integrity and mechanical properties even when exposed to aggressive chemicals and thermal cycling up to 500°F, solving common failure points in chemical processing, aerospace, and automotive applications. The precise inch system dimensions (1.25" OD x 0.203" ID) ensure proper load distribution for No. 10 screws, preventing stress concentration and extending equipment lifespan. The white PTFE construction with Durometer 55D hardness provides reliable performance in sealing, spacing, and insulation roles where metal washers would corrode or degrade under extreme conditions.
