LPG Thumb_Wheel 23mm

LPG Thumb_Wheel 23mm (approx)
Hand-wheel for LPG (propane) 23mm gas hose nut Australian standard
i.e. POL fitting hand-wheel for the nut on the regulator end of the Gas Hose.

An adaptor so I don't have to use a spanner to tighten my LPG/propane fitting.
Used for BBQs, camping stoves, gas grills, patio heaters, also can be used in boats, caravans, RVs, motor homes etc.
For the male POL gas bottle fitting i.e. from the gas regulator, typically utilising a left-handed or reverse thread.

Warning:
Please make sure you check the O-ring/rubber and test your fitting for leaks using soapy water once tightened.
Mine had a cracked O-ring!
Serious burns around the feet/ankles can be caused by gas leaks - it falls as it is heavier than air, then can ignite causing fires and injuries.

Quick easy print.
On my BBQ it was a firm, snug fit.
(Other countries seem to use different sizes, e.g. 30mm or 27mm)

I tried to look up the spec. standards, and I haven't found any so far after 45 mins., so I simply went by the measurements on my BBQ and other LPG gas appliances.

I used ABS as that was loaded, but PLA should be fine.
