This paper summarizes the key performance characteristics of compression and lip seals. Stable sealing relies on good medium compatibility to suppress material swelling. High temperatures reduce tensile strength, inducing stress relaxation, permanent deformation and seal failure. For dynamic seals, greater hardness enhances wear resistance and service life. Sealing materials should possess low permanent deformation and high elasticity and resilience, as extreme temperatures aggravateate deformation. Material elasticity provides resilient sealing force for compression seals and compensates eccentric contact stress for lip seals. Proper hardness matches surface roughness and working pressure to avoid leakage and extrusion, despite hardness degradation at higher temperatures. A wide temperature tolerance prevents thermal aging, hardening and elastic performance deterioration.
READ MORE Seals are divided into compression seals and lip seals based on working principles. Compression seals realize sealing by compressive deformation of the seal in the groove to block leakage paths. Lip seals initially obstruct leakage paths via pre-compressed elastic deformation. When subjected to medium pressure, their sealing lips cling tighter to the mating part for improved sealing performance.
