Bending brass valve stems

[jdogg]

Is it possible and what is the best way to go about it? I have a solid rim with a tubless tire that always leaks a little at the bead and cant see or feel any reason for the leak and if I dont keep an eye on it it deflates and I loose the bead seal! Ratchet strap trick has not worked for me even with a huge compressor and not big on the lighter fluid trick! Only thing that sets the bead is taking it to a tire shop and have them shoot it with the huge tank at the bead but would rather just tube it but the valve stem is not reachable at a 90* angle on either band brake side or sprocket side! Would like to put another 90* angle in the stem to make it accessible! Would a spring made for bending small tubing inside help keep it from crushing or would it just crack? I have a tubeless valve stem in there now that can be easily turned to fill it but would obviously have to go when I put a tube in! Any ideas fellas and ladies? Thanks all!! :thumbsup:

I think it will crack...there are many different brass alloys and those stems are pretty hard I thinkk.
They do sell a thread on 90* valve that screws over the original...I was going to try them on the reversed rims on my old Ford coupe but was always worried they would leak .

That's what I have on one of my Tom Thumbs because you can't reach the valve stem. They work well.:thumbsup:

Thanks Gerry!! That might be an option for me! Anyone have any input on these if they leak or not?
Heres what I'm dealing with! Any other ideas for this setup?

Instead of starting a new thread can anyone tell me what size inner tube to use for a 15x5.00-6 tire......ive searched alot and dont see one specifically for that size so I'm guessing something close works? Any ideas? Thanks everybody!! :thumbsup:

I don't know if it will work for brass but I have bent this copper tube by first filling it with grinding dust and pinching the ends. I think sand would have worked also.

Thanks Sixpac! I have used sand on copper tubing also but I think brass is much harder and no way to heat it up to un-anneal it to bend it easier with out melting the innertube! I did order a set of these so we maybe I wont have to bend them!!

As far as the tube goes, if it is a bit smaller than the tire it will work an stretch up to it's fit but, has to be 6" rim size.

Oversized tube will fold inside an at some point crack and leak.
Always check for plastic type tag(s) inside the tire, it also will cause a hole in the tube over time.
Remove that tag by any means possible, a dermal with a buffing stone should work well.

If that is your wheel you need a straight valve stem, Tire shop will replace it for a couple bucks. Pull the tire back and run a layer of grease on the tire bead, Problems gone.

Hey George! Thanks for the grease tip! Actually the stem thats on there works great as it can be turned to any position but would not be able to use that if I went with a tube (just turned it like that for the picture) ...which I realized is not an option anyways as the valve stem hole is offset and wont work with a tube! I guess this style rim is tubeless only :shrug: Thanks everyone!!

Most tubes have an offset stem an almost never in the center of the tube
