Does the urethane spider hold up better in cold temps than the buna-n version? We run equipment in some pretty harsh conditions and need something that won't get brittle on us.
Answer by: Customer Support on Apr 19, 2025, 8:20 PM
Urethane has a notably wider cold-side range than buna-n. The buna-n spider bottoms out at -20°F, while this urethane version is rated down to -80°F. Both top out at 180°F on the high end. If cold exposure is a real concern in your operation, the urethane is the stronger choice between the two materials.

This urethane spider is meant for the FC090 through FC095 coupling sizes, so it matches an FC090 application.
