Uniseal - 4 Inch - U400

Bought these for use in a custom rainwater filtration system, and they are working very well, no leaks. I couldn't find a 5 hole saw, so I ended up tracing a 5 hole, cutting it with a jigsaw...and no leaks. I'm happy with the purchase, and happy with the result.

This is a great product at a great price. They are easy to install, very good seal, and much neater than a bulk head.

Simple and inexpensive, but highly effective, solution to the problem of sealing a 4 inch PVC pipe penetration through the side wall of a 55 gallon drum. The horizontal wall curve discouraged the use of a bulkhead seal; however, this solution was a natural. I will reorder soon.

Have not installed the seals yet but they look great.

Got the seals I order much quicker than I thought I would and they worked great. A couple of bits of advice to make it easier would be to heat up the seal (heat gun, etc) before you install the pipe and to put grease on the pipe. I tried soap at first and ruined a seal trying to get the pipe in. Then I used vegetable shorting and just cleaned it off after, worked like a charm.

The Unseals make work so much easier and the Unseal warehouse supply them to me in Australia in a very quick 7 days. No complaints with the product and the supplier. Thank You, Lawrence Wasley.

Great product!!

Worked perfect for my secondary septic tank worked great where a bulkhead would not
