Radiator Valve Spud Wrench

The tool was much stronger than the brass pipe I was using it on. Doh!

This spud wrench is a zinc casting, a soft metal. It will install new stuff, but will break in two pieces if used to remove a half-inch or three-quarter inch bushing old enough to require a sturdy wrench and a four-foot helper to get the old bushing off the radiator. I made a spud wrench from a hardened steel 3/4 inch bolt with a 2 inch shoulder and cut off the threaded part. Next, I cut two grooves into the shoulder to make a spud wrench strong enough to overcome the expected resistance. After I got the old bushing off the radiator, I used a wire brush to clean off the rusty thread on the radiator. Used the new spud wrench with Teflon plumber tape to install the new bushing into the radiator. Need the tape to insulate the brass bushing from the cast iron radiator. This avoids galvanic corrosion.

Great product good quality spud wrench just what i needed i recommend this product

Bent and then broke off during 1st use.

This is a simple unit to have for anyone that owns radiators.

Fast shipping . The tool helped remove and replace some valves

item works great big time saver.

works well, just what was needed.

Does not work well to remove small valves (1/2" and 3/4") . The stud wrench is narrow at the end and on the first valve the wrench snapped in half. Would probably work well for larger valves. Supply house was fast to fix the broken wrench.

When you need a spud wrench this will do the job very well.
