Due to their unique four-lobed geometry, grooves for Four-lobed Seals are different than those for O-Rings. In general,Four-lobed Seals grooves are deeper, as less squeeze is required to affect a positive seal. Four-lobed Seal grooves are also narrower due to their ability to resist “spiral failure” better than O-Rings. The following chart displays general recommendations for Four-lobed Seal grooves.
