Product Identity
The L.H. DOTTIE HPS312 is a cup and die set designed for 3-inch conduit work. It serves electricians and contractors who need to form precise cups and threads on rigid metal conduit during installation.
Sustained Operation Behaviour
The hardened steel construction resists wear when forming multiple conduit ends in sequence. Consistent alignment between cup and die maintains thread quality across repeated use without deformation of the tool faces.
Conduit Size Constraint
This set is dedicated to 3-inch trade size conduit only. It cannot accommodate smaller or larger diameters, so crews working with mixed conduit sizes will require additional tooling for other dimensions.
Highlights

Questions about this item
Will the 312 set run hot during continuous conduit bending?
The HPS312 is a manual cup and die set with no motor or electrical parts, so it generates no heat during operation.
What bender frame or hydraulic pump is needed to use this cup and die set?
The set requires a compatible 3-1/2 inch cup and die bender frame or hydraulic bender that accepts 3 inch conduit tooling.
Can the 312 dies work with my existing Greenlee bender shoes?
The HPS312 dies are made for Dottie 3-1/2 inch cup and die systems; they are not interchangeable with Greenlee shoe-style benders.
