I bought a 'used' roarer burner from base camp, and come to find it leaks from under the nipple. the nipple is extremely tight, so I guess it was cross threaded. Any ideas on sealing it up? I don't know how hot it gets , will ptfe tape or the hi temp rtv work? Perhaps a copper washer? Any help greatly appreciated!
The nipple doesn't get all that hot, so a teensy dab of copper bearing hi-temp rtv will do the trick. I have gotten several roarer burners back in service through the "good offices" if you will, of that stuff. Take a brass wire brush to all the mating surfaces to be sure everything is as clean as possible. A brass M16 toothbrush is what I use. Get the nipple screwed down just snug, then let it set for an hour or so to cure a little. Gerry
Loctite make a high temp thread lock-come-sealer. Negates the need for calmonite washers, so see no reason why it wouldn't work here.
Gerry, What is this stuff? I could use it with an old Optimus 45 that has the same problem as Steve's. Chuck

There's also this one. I always put a smear of this on the threads when I refit burners. It does the job whether you fit a heatproof washer or not.
same problem, my "go to stove" has sprung a "nipple leak"; she is already tight so am scared of over tightening and screwing things up again has anyone tried exhaust assembly Hylomar paste label says stable up to 1000 degrees Celsius? http://hylomar.com/hylo-wp/wp-content/uploads/2013/10/Hylomar_Exhaust_Assembly_Paste_TDS_2011.pdf]Link Hylomar Exhaust assembly paste[/url] am very tempted to try it as have seen it used on exhaust manifolds.....but a bit worried if I have to take the nipple out again the Hylomar Blue is good to 250 Degrees Celsius and like it cause it is a LOT less expensive + can be taken off again w/o binding BUT is 250 Celsius less than what the burner nipple is exposed to during normal use . http://hylomar.com/hylomar-product-range/gasket-jointing-compounds/#universalblue]Link Hylomar Blue[/url] hate the idea of sticking something in and have to drill it out if anything happens all advice and suggestions appreciated; cheers Lou
Take the jet out and look at the seating areas of the jet and burner, you may have a small nick. Also check the threads for burrs. Ken in NC
Ken, I took it out and cleaned it and the threads; looked at the nipples threads and they look ok under magnification; very awkward to get to the burner side threads BUT they do look ok under my triphocals ; just think it has been overtightened so it bottoms out w/o making a good seal; will have to think of something to seal the threads; was thinking Hylomar cause it is not a hardening type of sealant + it is fuel and heat resistant.........cheers Lou
