Dixon Boss male spud, 1"

This Dixon Boss ground joint male spud has an NPT thread and a polymer seat. This range covers eight sizes from 1/2" to 3", in plated steel up to 1" and plated iron from 1-1/4". In a Boss coupling the spud is usually fixed to the equipment and the stem is clamped to the hose.

Turning the wing nut on the spud connects or disconnects the two halves, and tightening it gives a mechanical and pressure seal. The non-metallic polymer seat resists most chemicals found in manufacturing facilities.

Key specifications

Choosing the right option

Then match the spud size to the stem and hose size in your assembly. Worn-out hose couplings can be dangerous. They should be checked regularly and replaced when necessary, and that each user should review the application and add safety devices where indicated.

Ratings are Dixon's Boss coupling ratings by size, so the rating of an assembly depends on the lowest-rated part, including the stem and hose.
