Natalie ★★★★★

My compressor seal was leaking, and these dash 463 o-rings matched perfectly — the nitrile rubber holds up well at higher temps. Nice tight seal on the first try.

Jacob P. ★★★★★

The 70 durometer feels firm but not brittle, and the AS568-463 fits perfectly into the groove I needed for a fuel line repair. They've stayed soft even after a few heat cycles up to 200°F.

Claire ★★★★★

These o-rings handled a quick hydraulic repair without any issue. The 70 durometer feels solid but compressed fine into the groove, and they should easily handle the -40 to 250 degree range I need. Fit perfectly on the first try.
