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.
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 Bradford™ clamps, ferrules and gaskets are used.
Bradford™ buttweld fittings are manufactured to very high tolerances. Some elbows are manufactured using a hydroforming method, which makes a more uniform elbow that is easier to weld and polish.
