I have to continue screwing in for another approx. 1 and a half turns before the rubber washer meets with the stove. Until they meet, I get quite a blast of cold gas on my arm. If the coldness were my only concern, I could just put on a long sleeve, but I am concerned with the amount of gas I lose also.

Is this a tolerance problem mentioned above?

Thank you very much for your input.


Not sure which stove you have. But the MSR Pocket Rocker has two seals. One o-ring at the valve and a rubber washer that sit on the shoulder of the canister. The last one is more of a backup seal and is more of a thing protect the valve from torque forces. On new lightweight stoves they skip that part to save weight.

You always get some leakage at the o-ring at the valve when screw a stove on a canister, but only a short burst. If it's more, but stops after continuous screwing it on, it's probably manufacturing tolerances or you have a o-ring that leaks/is absent. The o-ring must seal the leak. The rubber washer isn’t what is supposed to keep the gas in.
