How does this grade compare with the rest of the Deacon range?

Across the 55 Deacon injectable sealants and compounds PE Energy stocks, this one is rated -50°F (-45°C) to 500°F (260°C). That places it above 8 of the other 54 on upper service temperature: PUMP 99, PUMP 77 PTFE Based Injectable Pump Packing stops at 450°F, and Pour-Shield™ Rubber Compound continues to 550°F.

Deacon publishes these ratings one product page at a time, so the comparison above is the part that is hard to assemble before you order.
