Ground joint fittings are designed for high pressure air or water (ie. up to 500 psi) as well as steam (steam maximum 250 psi @ 450°F max) in plants, refineries, construction sites, or drilling applications (pressure ratings are for a guide ONLY as they vary based on service conditions, temperatures, etc.). Ground Joints are NOT for use with toxic fluids or flammable gases.

Warning: <<Always inspect/tighten bolt style clamps before each use>>
