حلقات O من بونا-ن نيترايل 0.103" بوصة CS × 2.111" بوصة ID | AS568-138 | داش 138 | صلابة 90 (300/عبوة)

The 90 durometer hardness gives these o-rings a solid, durable feel that I trust for sealing applications. I've been using them on a hydraulic repair job, and they hold up well under pressure without any visible deformation. Exactly what I needed for the 2.111" ID fitment.

The 2.111" ID fits perfectly on my hydraulic cylinder gland, and the 90 durometer gives them a firm seat without any squish. I've had them in service for a month now, no leaks, no swelling at 180°F oil. For a three-hundred pack at this price, they're a solid buy.

The 90 durometer makes these o-rings hold their shape perfectly in high-pressure hydraulic fittings. I replaced some old seals and the leak stopped immediately—the 2.111" ID was a spot-on fit for my application.
