* Service ratings are based on hydrostatic tests using standard-molded Buna-N material gaskets, with proper installation of ferrules, assembly of joints and absence of shock pressure. Contact Tri-Clover for service of other type and material gaskets, and for ratings at higher temperatures.

All ratings shown are dependent upon related components within the systems and proper installation. For temperatures above 250°F, we recommend using only 13MHP clamps. This information is only valid if Tri-Clover clamps, ferrules, and gaskets are used.
