Default old optimus hiker stove problem

Okay I am going retro.

I had an old optimus hiker, when it gets going the pressure builds up in the gas tank and releases the gasses through the top of the filling lid and thenit caugh on fire from the stove. Is this safe? I used it many times like this before but I think it is time to do something about this.

-How to I fix the nipple and correct the pressure release tenion spring in the nipple?

thanks

Hiking stoves are by their nature unsafe. They combine high pressure, volatile liquids, explosive gas mixtures, asphixiants, confined spaces, tired befuddled operators, etc. But compared to all the other risks in hiking, stoves might be at the lower end of the scale. IMHO, I would keep using it until it burns something expensive like a tent or a sleeping bag.

Those swedes knew how to make good stoves.

Found this



Looks like you can get parts form the UK
But I would suggest if you looking for another stove like this. Try getting a green colman white gas off craigslist 25-40 bucks

Thanks everone,

getting another stove is not a problem but I feel bad throwing away a good stove I can salvage, The hiker is a good base stove. Yup they just came out with newer design with green puking looking fuel tank. No thanks. I'll see if this works if not in the trash it goes.. Thanks for the reply. Happy hiking

Sorry late answer. the Optimus 111 hiker has been made in several versions, but the cap with safety valve is still the same. Newer 8R and Svea 123(R) has a the same cap. (And a lot oders too.)(R = buildt in cleaning needle (rensenål))

The safety valve should open at a pressure of about 2.5 Bar (~ato)and closes when the pressure has dropped.

The Hiker stove was orginally made in 2 versions with roare burners (It has a flame ring instead of a perforated cap) Those marked B (Sweedish Bensin =gasoline)were of course gasoline models, the oter ones was kerosene models, but works reasonable well on gasoline.

Later with silent burners it has been a lot of variants, but all has been sold as triple fuel and multifuel.

The latest with green and black paint is just an Optimus Nova on a Hiker tank.
