حلقات O من بونا-نايتريل | 0.103" CS × 0.924" ID | AS568-119 | داش 119 | صلابة 50 (300 / عبوة)

The dash 119 size fits perfectly into my hydraulic repair kit, and the 50 durometer firmness feels just right for the sealing job. I've used these in applications from cold winter mornings to hot summer afternoons, well within that -40 to 250°F range. Having 300 on hand means I won't run out mid-pro

I was pleasantly surprised by the quality of the rubber for the price—the 50 durometer feels firm but still flexible enough to seat easily in the groove.

These fit perfectly into the groove I machined and the 50-durometer material seals nicely without needing excessive force. The temperature range down to -40°F gives me confidence they’ll hold up in my outdoor equipment this winter.
