Proportion Valve leak

The valve is leaking out of the small rubber seal on the rear outlet. This a new valve. Anyone know what would cause this and what this is for? The round seal right under the mounting bolt.

Re: Proportion Valve leak

I went through three of them before I got one that didn't leak.
All are pretty much from the same company in China.

Weird. Might have to replace it.

Re: Proportion Valve leak

I will second Accelo's comment. Find the correct PV on Amazon or other easy to return site and rotate till you get a good one. The expensive ones are just marked up. Not better.
