TORK Distributors is compatible with Compool 1.5" and 2" Diverter Valve O-ring Kit 51016200, 192039

They do fit properly and are very good. However, I wish that the spacer was included since mine was broken.

Never pay double the price for items again. Quick delivery and quality as good as Pentair.

Perfect replacement part

Just as described

Works as expected.

These are a great buy, they fit perfectly and stopped the air leak on the low pressure side. Easy to install, and the company shipped fast. Would buy again.:-)

Nice replacement part that does the job.

These didn't fit for my application. I don't think the measurements are correct (or I misread them maybe?). In either case if possible I'd probably suggest taking your part to a store to find as descriptions can be misleading.
