Ordered one of these by mistake

[WaterTight]

And given the cost won't be bothered to return it. But am struggling to think of what it would be used for...

I mean I know what it does, but when would it be useful?

McAlpine 1 1/2'' Straight Connector BSP Male x Universal

 

[ShaunCorbs]

convert this to 40mm both sides

Self Closing Waste Valve - Loose Nut x Compression

or on the hep fanny traps

 

[Harvest Fields]

For a hepvo trap

 

[WaterTight]

Ah yes.

Fanny Traps? One of the best silent move stars there ever was.
