Description
This red John Guest stem plug inserts into an unused 12mm push-on fitting port to close it off. It is useful for leaving a spare outlet for a later addition or isolating an unused branch; unlike an end cap, it does not fit over the end of 12mm pipe.
Features
Allows you to design your plumbing installation for future additions - or change your mind and seal off outlets.
Very useful as a spare part in case you need to isolate part of your plumbing system.
