Question by: Patty P on Nov 8, 2025, 10:41 AM

What's the deal with the temperature range on these spiders? I'm seeing Buna-N and Urethane... which one is better for colder weather?

Answer by: Customer Support on Nov 9, 2025, 5:56 PM

Urethane spiders handle colder temperatures better. Buna-N spiders are good down to -20°F, but urethane can go all the way down to -80°F. Both top out at 180°F.
