حلقات O من HNBR 0.103" CS × 0.611" ID | AS568-114 | داش 114 | صلابة 80 (100 / عبوة)

Had to replace some old seals on a high-temp pump, and these have held up perfectly so far. The 80 durometer feels noticeably stiffer than the generic ones I tried before.

Finally found the right size for my hydraulic fittings without having to order a custom batch. The 0.611" inner diameter sits snugly and the 80 durometer feels firm enough to hold up under pressure. Nice that they cover up to 300°F, which is exactly what I needed for a hot oil line.

Installed these on a hydraulic fitting that sees some heat cycles, and the -40°F to 300°F range covers what I need. Good snug fit with the 0.611" ID, though the pack of 100 is more than I'll use for a while.
