Yep... got that.... but what were/are you trying to achieve?

Looks like a standpipe?
I've tried a few options and I'm currently at the cheapest/secure trade off option that I've found.
40mm uniseal ($2.50) and presure pipe with a joiner (joined in the growbed side) in between the pipe that goes through and the stand pipe (for easy detachment and removal.

Hi RupertofOZ,

just wanted a good replacement for a 25mm grommet. Don't need many of them, so my little modified toilet grommet will do the job. I have male/female 25 thru tank couplings and then there is the normal tank fittings. So I need 1 for my FT, but there are other alternatives.

The best place around my area is the Irrigation Shop 29 Moss St Underwood. Online they show 13-19-25mm TH grommets.
Then when I went there they said the firm that makes them has discontinued them Antelco is the company. Other than that they have all the fittings that I need.

If some of my sentences are a little hard to follow please excuse me. Age is catching up fast lol and the brain doesn't quite compute the way it used too.
