Possible Propane Adapter(?)

Unread postAuthor: THUNDERLORD » Sun Jun 15, 2008 11:49 pm

I recently got a standard Husky blow nozzle and it came with some extra nozzles. (About 8$, No camera right now but I could link to it)

One nozzle had a rubber tip. The back had two types of threads, back to back, seperated by an o-ring.

It looked like the larger thread would fit the threads of a propane torch base. But the smaller thread section made it too long to check so I put it in a vice and sawed the smaller threaded part off.
It fits (threads match).

The problem is when I cut the rubber tip off, it left a part about 5/16 diameter and only 3/8" long.

Looks like it could be jb welded or epoxied into a hose barb base.
Not sure if that would hold.

I am wondering if it could be soldered on.
I was thinking about replying in MrCrowley's how-to but I have a few questions too many about this new adapter.

Thanks 8)

Upon DYI's recommendation, I've just been buying the Bernzomatic basic flame torchand with 2 Big A pipe wrenches, breaking loose the crooked pipe that's threaded into the tank adapter and valve/knob.

You've got to really put some muscle into it but it will finally break loose...some fancy loctite type gunk in there. Once it's out, a 1/4" compression to 1/4" MIP brass fittingwill screw into knobbed valve adapter...it's a beautiful thing actually... :)

Right well, the bernzomatic torch you linked to is the one it screws into (after removing the pipe nozzle).
And the valve adapter you linked to is 13$.
This one came with an $8 blow nozzle I will use anyway.

I really don't see how this would work.

Still, no camera access but I found a link to it:<a href="http://fp.vendaria.com/vpop/VpopViewer.html?uid=100073836&iid=AddpfzvImumvmKvJJIIKfwKILumLKv&bg=FFFFFF&nm=BZOpener&err=0&title=&pf=t&fr=t">the rubber tipped nozzle here</a>

Hope the link will work.
I'll try to post pics of how I've chopped it, when I get my camera.

Looks like a smaller version of the tip I saw on a helium tank for filling balloons? Strange. :roll:

I still don't see how that the rubber nozzle can be used on a propane bottle:/
Maybe I'm just dumb, I have one, it seems far to small.

The larger threads on it fit a bernzomatic standard torch tip.
Once the smaller threads are sawed off.
Like the one Starman linked to (when the pipe part is removed).

Like I explained, I cut the rubber tip off (w/ utility knife,sort of a pain).
It exposed a 5/16" diameter by only 3/8" long brass end inside the rubber part.

The 5/16" diameter is only slightly smaller than the ID of the base of a hose barb.
So I'm planning on soldering/JB welding(epoxy) it in there and/or thread it for a set screw.

Then I will hose clamp a pneumatic hose on and thread it into the bernzomatic torch tip. 8)

ooh ok, so the threads that take place right after the bend...ok ok I catch your drift.
another solution that I have seen is cutting off the bend on the torch head, and putting a hose+hoseclamp right on the brass

Don't you just love that sickening "crack" it makes when it breaks loose? Every time I've done it, I thought I'd snapped the brass pipe. A hell of a lot better than sawing it off and attaching a hose clamp though.

So the whole crooked pipe is threaded into the main base?

Yep. Amazing how few people in this hobby actually realise that... And the threads are 1/4" compression, nice and convenient.

I have seen an adapter for a standerd propane tank, it goes from propane threads to npt 1/4" pipe threads..I was thinking of using it as a portable air sorce for my gun.
