Sealing the joint between two mating parts, this O-ring compresses into its groove to fill the gap so oil, air, or hydraulic pressure cannot escape past it, serving as a static or dynamic seal at the interface it sits in. O-rings harden, take a set, and crack as they age against heat and chemicals, showing up as a weep, a drip, or a loss of pressure at the joint.
An O-ring seals the joint between two mating parts by compressing into its groove, filling the gap so fluid or pressure cannot escape past it. This ring serves as that static or dynamic seal in the assembly it was cataloged for, holding back oil, air, or hydraulic pressure at the interface it sits in.
O-rings harden, take a set, and crack as they age or run against heat and chemicals, and a failed ring shows up as a weep, a drip, or a loss of pressure at the joint. Because rings of different inside diameter and cross-section look alike, match the ring's bore size and thickness to the groove it seats in when replacing it, since a ring even slightly off in either dimension will not seal correctly.
