What is ID.me?
A watertight, threaded through-wall fitting for anywhere a pipe needs to pass through a pond wall, skimmer, filter tank, or vault. This is the standard way to plumb a skimmer or return line through poured concrete or a rigid tank wall without risking leaks at the penetration point — eight sizes cover everything from a small 1/2" line up to a 4" high-flow line.
Heavy-duty, corrosion-resistant construction with a compression gasket on both sides of the wall, so the seal holds regardless of which direction pressure is coming from.
| Model | Pipe size | Required hole size |
|---|---|---|
| BF50N | 1/2" | 1.25" |
| BF75N | 3/4" | 1.50" |
| BF100N | 1" | 1.75" |
| BF125N | 1.25" | 2.25" |
| BF150N | 1.50" | 3" |
| BF200N | 2" | 3" |
| BF300N | 3" | 4.625" |
| BF400N | 4" | 5.75" |
Every plumbing penetration through a concrete pond wall or rigid tank needs one of these — skimmer line, return line, or filter connections. Most builds need two or more.
