These fit perfectly on a Parker Hannifin fitting where a standard Buna-N kept degrading. The neoprene compound handles the Freon exposure without swelling, and the -45°F rating gives me peace of mind during winter service calls.

I bought these for a refrigeration repair and the -45°F rating gave me confidence they'd hold up in the cold. They seated perfectly on the first try, which saved me a lot of time.

Used a handful of these to rebuild my old hydraulic valve, and the -45°F rating gave me peace of mind for the winter. The 70 durometer feels plenty firm yet seals nicely against the groove. Seven hundred in a bag means I won’t run out for years.
