Question by: Sherry C on Aug 22, 2025, 6:16 PM

What kinda temps can these wiper rings handle before they give out?

Answer by: Customer Support on Aug 24, 2025, 7:03 AM

The standard urethane material is rated for temperatures from -65°F to 220°F. If you need something for hotter conditions, look for the fluorocarbon option (indicated by a "V" suffix), which can handle -20°F to 400°F.
