Not a perfect fit for part 42218
As the only customer who submitted their review, the dimension of this unloader is slightly different.

Not same as OEM
Installed new unloaded valve because old one was washed out. Compared new and old valve when I received new one and noticed it was longer than old one. Gave it a try anyway and could not get it adjusted to work as it should. Would not bypass pressure when letting off trigger unless I backed adjuster off so much that it had no pressure when pulling trigger. Would get hot and pop thermal relief valve. Took the new and old unloaded apart to see why one was longer than the other. The new one was missing an o-ring and also a washer/spacer that would have put the plunger at the correct length. I took the new valve seat and the little plunger/valve(not sure of correct name of the individual parts) and put in old unloader. Put back together and could adjust properly. Bypass worked and also had great pressure. I knew I should have spent the extra money and bought OEM part.
