About Washers

These washers surpass most other plastic washers when it comes to withstanding chemicals, oil, and grease. All are excellent electrical insulators.

PTFE washers withstand high temperatures and have a slippery surface that resists wear in high-friction applications.

PVC washers resist acids and alkalies.

PVDF washers—also known as Kynar washers—have excellent chemical and corrosion resistance. Use them in applications involving high temperatures and harsh chemicals.
