حلقات O من HNBR مقاس 0.139 بوصة CS × 1.734 بوصة ID | AS568-224 | داش 224 | صلابة 90 (25/عبوة)

The 90 durometer feels nice and firm, exactly what I needed for this hydraulic fitting. Sealed up tight on the first try and seems like it'll hold up well in higher temps.

These fit perfectly on the 224 size fittings I needed, and the 90 durometer HNBR handles the heat and chemical exposure in my hydraulic lines without any swelling. The 1.734" ID sat snug without any rolling during install, so I'll definitely be ordering these again.

The 90 durometer feels noticeably stiffer than standard o-rings, perfect for my high-temp pump application. It seated easily in the groove and held pressure without any leaks even in my hot water test this morning.
