Swell Blanking Cap

The Swell Blanking cap is used primarily on the Kockney Koi bay filters or tank connectors to blank off the drains. It can be fitted onto other branded filters but bearing in mind it has a female thread of 158mm (O ring supplied). If you are looking to cap off a piece of solvent pipe with no thread then why not try our Swell Rubber Caps that are available in 1.5", 2", 3" and 4"
