حلقات O-Ring من Viton FKM مقاس 0.103 بوصة CS × 2.424 بوصة ID | AS568-143 | داش 143 | صلابة 75 | أسود (50 / عبوة)

Used these for a hydraulic cylinder rebuild on an old press that sees 300°F oil; the Viton material handled the heat without any softening. The 75 durometer felt firm but still sealed nicely in the groove.

Popped these in a high-temp sealing application that other o-rings couldn't handle, and they haven't cracked after dozens of thermal cycles. The 75 durometer feel is firm but still flexible enough to seat perfectly in the groove. Exactly what I needed for a lasting fix.

Needed to replace some old o-rings on a hydraulic line that sees high heat, and these Viton seals are rated perfectly for the job. The 0.103" cross-section made for a snug fit inside the groove, and the package of 50 gives me plenty of spares for future repairs.
