Ive weighed the original propane tank with caps top and bottom (plastic) to be around 854 grams.. I cooled them for about 20 minutes and filled...One container went to 900 grams,checked with the solution for leaks and no problems...Do other people put a bit more in or stick to the original grams of 850 or do you put a bit less...


Cheers

I would suggest that it is not a good idea to cool and fill as you are reducing the natural expansion space in the container.

This could lead to leaks or worse as the container heats up in the midday sun.

Not game to overfill if you pop the safety plug particularly if the canister is in your car you could have big problems including insurance
also i'm not sure what the safety is set, at you have overfilled by about 5% should be ok as they would have a safety margin just my thoughts

For any one who may wish to purchase a Mac Coupler from the U.S.

RV Outpost is the place to buy. Mrs. Julie Mic is well respected on one caravan forum in particular. She goes out of her way to look after Australian customers and is building a steady client base from Aus.

Ian,

Totally agree with your statement matey.

A great Company to deal with and from memory, the postage was only about $11. Notice they are currently out of stock of the MacCoupler at present.

They also have "Mac Caps" which would be better than the original plastic ones.

Hiya Ian W

You keep mentioning this company when mac couplers are bought up...But if a company cannot be bothered keeping up with stock they loose potential customers...I wanted to use them because i wanted to buy the mac caps as well,but i got sick of looking at the OUT OF STOCK page...

So i used another dealer...

How long is one supposed to wait,well respected or not..

Just fill as per instructions.

chill in freezer for 20mins, then allow to equalise on cylinder for about a minute, you can hear when gas stops transferring.

I used to weigh them, but dont bother now, you dont have any control to overfill or underfill anyway, it will vary by 50grams or so, depends on ambient temp of cylinder etc.

So chill n fill n enjoy the cheap cheap gas
