Worked great, no leaks
Nice seal. I didn't need anything extra for this to be perfectly leak free on my 55 gallon pond natural filtration bog filter.

Be sure of the hole size before you drill!
Value for money: These things are amazing! Just be sure to look at the conversion chart, if you're lucky enough to get one in your package. If not one there, then be sure to contact them for the size hole needed before you drill the hole.

Perfect Fit
The hole guide for drilling made a perfect fit for the gasket. Installation was easy and the seal was tight.

Work just as expected
SSo great to have this simple tool to make a home made pond filter. Mine has really cleared up my nasty pond mess. Just watch the U-tube videos and make your own. It works better than anything else!! Nice clear water in my pond now!

No leaks!
I was a little concerned buying these. But I took a leap of faith and I’m glad I did they work perfectly. No leaks at all.

Great product
works great for flood and drain system Drilled 1/8 inch plastic for a bell siphon 1" pvc worked great When using your hole saw on plastic run your drill backwards after you go through with with the pilot hole. If you run your hole saw forward on plastic there is a big chance you will wobble the hole oversize. Pipe ID - 1'' (25mm) Pipe OD - 1.315'' (33mm) Holesaw size: 1.75'' (44mm) Up to 3/8" Wall Thickness. (9mm) I really enjoy reading some of these Amazon reviews where ignorant people mutilate their projects and then blame the product they purchased for their incompetent skill set
