Can I apply the FS4W sealer underwater?
Yes. The nitrile rubber chemistry lets you apply this sealant directly below the waterline, so you can patch a vinyl liner or seal a plaster crack without draining your pool.
What is the difference between the FS4W (white) and FS4B (blue) sealers?
The chemistry, 4 oz tube size, and performance are identical. The only difference is color: choose FS4W to match white vinyl liners, plaster, or fittings, and FS4B when you are sealing a blue liner or blue tile.
Can I install this myself, or do I need a pool pro?
This is a DIY-friendly repair product. Clean the surface, cut the tube tip, squeeze the sealer onto the leak, then flatten it with a wet finger. For large structural cracks or repeated liner failures, have a pool professional inspect the underlying issue.

Let customers speak for us
Easy to order - received the next day!
Beautiful!!
The valve fit perfectly and works great.
Fast shipping and great price!
Does what a small weed- eater would do it minutes versus an hour
Great product does exactly what was advertised to do.
I ordered the wrong part. Customer service was very helpful. I returned it and within the week my credit card was credited back. Excellent customer service policy.
There was a delay in shipping due to postal service. They sent another part right away.
New model 59303 works great, but too bad the last generation Balboa WiFi module 50350 became un-useable.
Exactly as advertised and super fast shipping and delivery
