Suggested Groove Design for Quattro Seals™

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

Seal No. Cross-Section Depth (dynamic) Depth (static) Width
004 thru 050 .070" ± .003" .060"/.062" .050"/.057" .080"
103 thru 170 .103" ± .003" .093"/.095" .088"/.090" .115"
204 thru 276 .139" ± .004" .127"/.129" .121"/.123" .155"
