About Washers

Metric Chemical-Resistant Plastic 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.
