Question: Will this fit a Hayward SP0710XR50 valve?
Document: This is a perfect fit for Hayward valve. When you install it make sure you have the Teflon grease. Also the old one is a bear to remove.
Correct sized gasket for the Hayward vari-flo valve. The O ring suggested is not correct so don't buy. It is a 2 inch not a 1.5 and does not fit....go figure
The valve seat under the valve wears out and doesn't seal properly over time. If you replace your valve, you should replace the valve seat gasket. It fit perfectly, just drop it in, verify all the fingers are seated and your done. Great product.
Received filter gasket and replaced along with Hayward Key Cover on my Hayward sand filter. Works great and no more water leaking through back wash hose.
Called Hayward to get install instructions and was easy to install although the old one's removal was a bugger to get it all out cleanly. It took me about 30 min to change out being thorough.
This gasket appears well crafted and fit like a glove. It completes its task for routing the water control via the sand filter handle.
This didn't match my filters model exactly, but it was a perfect fit. The old gasket was worn and continually needed re-seating or it would lead out waste hose and between sections. At 12$ shipped, this was a good price too.
I have a very old pool filter and this fit it perfectly. I liked this one because they told you the size in the description (not all sellers do) and so I did get exactly what I needed. And it's far easier to install then you would think!
Was exactly what we were ordering from and there was a little problem with my address, they called me right away and I recieved it right away!
I searched and found a great price here. I purchased it and got it very fast and in good condition.
Answer: yes
