On the heater side I used 10mm brass "Gas Nozzles" from B&. They are a tight fit - the minibore needed to be dipped in boiling water & forced on & then secured with 2 jubilee clips on the hot side, so you loose the quick disconnect feature, but they never leak or pop off & you can still undo them in 2 mins with a spanner if you need to.
On the hose reel side, my hose reel just had a 90 degree swivel with a brass hosetail on it - again I just pushed the minibore on & secured with 2 jubilee clips. simples!
The minibore from Sureclean is VERY good though (So is their pole hose) - - other brands might not survive the heat so well...
I used standard minibore from Sureclean systems & never had issues - - except it does need double jubilee clips on all fittings as it goes quite soft when hot.
Hi Nat, what connectors do you use for connecting to hose reels?
