حلقات O من النتريل بونا-N | AS568-151 | داش 151 | صلابة 50 (125 / عبوة)

These seals handle the -40°F to +250°F range effortlessly, which is exactly what my hydraulic setup needed. The 50 durometer compound gives them enough flex to seat properly without tearing, and I’ve got plenty to spare for future rebuilds.

Finally, a pack of o-rings that actually fit my old air compressor without leaking. The 50 durometer rubber is noticeably softer and seals better than the generic hard ones I've tried before. For the price, getting 125 in the standard AS568-151 size is a solid deal.

The temperature range is broad enough for my outdoor gear, and the price for 125 pieces feels fair. I just wish the package included a few spare sizes for common fittings, but these work perfectly for my dash 151 needs.
