1/2 Inch Radiator Cap

1/2 inch blanking cap for radiators.

I made this to use as a blanking cap whilst I changed a towel rail, and didn't fancy leaving the ends of the TRV / lockshield for a few days open becuase, well - you know, water.

1/2 inch BSP thread on internal diameter, be careful not to overtighten as it can split the layers, best printed cap down. Haven't tested under pressure, but no reason why it wouldn't work - recommend using ptfe tape around male thread end becuase that stuff is amazing and cheap.

I couldn't find one on here so I thought I'd make it, hope someone else finds use out of it

Printed at 0.2mm layer height on Cura print time approx 30mins (quicker than nipping to ScrewFix!)
