GROUND JOINTS

Also known as “Boss” Fittings”,  Ground Joints provide a convenient NPT threaded fitting for high pressures.

The spud portion of the fitting is usually fixed permanently to the equipment, and the stem and nut attached to the hose are the other half.  The wing nut on the spud can be rotated to easily achieve the seal on a tapered seat.

Our Ground Joints are steel plated.
