On the topic of Ronson type fill valves, I’d like to share with those of you who may not be familiar with using these valves a couple quick pieces of information the may be useful.
The thread size they use is M4.5 X 0.5
As I mentioned in earlier posts, these fill valves are commonly used for refillable Butane/propane gas tanks purpose made for steam engine boilers within that wide range of hobbies.
I used to be one of those manufacturers more than a decade ago and produced a wide range of engines, boilers, fuel tanks and other bits for the marine hobby market.
I’ve attached some photos of a commonly designed style of a refill adapter available from a number of model steam engine manufacturers who sell refillable fuel tanks.
These are made to thread onto the disposable fuel canisters for light weight backpacking style camping stoves that use 70/30 mix of butane/propane which are available at most outdoor recreational stores.
I forget off the top of my head the exact Size and thread count used on these canisters, (I would need to dig through my old design archives) but here is the good news. The size and pitch that is used on these canisters is also common across a number of other disposable canister products, including airbrush propellant canisters.
These Ronson type fill valves are especially useful when space and weight requirements within a design do not permit the use of a tire style shradder valve stem.
Hope this information is helpful to some of you out there.
