Customer Reviews (4.6 / 5 · 5 reviews)

Avery L. ★★★★★

My old bushing finally gave out, but this M5-B replacement fit perfectly on my RSG250 and the electrical insulation feels solid during use.

Riley S. ★★★★★

The insulation on this bushing feels solid and well-molded, which gave me confidence during installation. It seated perfectly into the spool gun assembly without any wiggle—just what I needed for a reliable repair.

Andrew Y. ★★★★★

The insulation on my old one was cracked and causing intermittent feeds; this replacement seated perfectly into the RSG500 assembly and the electrical resistance feels solid again. Took maybe ten minutes to swap out and the gun’s been running smoothly since.
