حلقات O من بونا-ن نيترايل | AS568-465 | داش 465 | صلابة 70 | أسود (10 / عبوة)

I was skeptical about the temperature range, but after using these in a hot fluid line near 200°F they've held up perfectly with no deformation. The 70 durometer feels just right for a snug seal.

These fit my air cylinder perfectly and the 70-durometer material has held up well through repeated pressure cycles. The -40° to +250° temperature range gives me confidence they’ll handle the cold start conditions without cracking.

Had to replace a leaking seal on a pneumatic actuator and these dash 465 rings were a perfect fit right out of the package. That 70 durometer hardness gives them a solid, reliable feel without being too stiff.
