حلقات O-Ring من EPDM | AS568-159 | داش 159 | صلابة 70 | أسود (50 / عبوة)

The temperature range is exactly what I needed for a steam seal application, and all fifty rings in the package look clean and uniform. Fit perfectly on the first try, no trimming necessary.

Installed these in a hydraulic line that sees -20°F startups and they seal perfectly without any shrinking or hardening. The -65°F to +300°F range gives me confidence in extreme conditions.

Installed these in a hot water application that hit 200°F and they're holding perfectly so far. The 70 durometer feels solid and the -65°F to 300°F range gives me confidence I won't have to revisit this job anytime soon.
