LF: Tank valve removal tool

[Wookie]

Or, get a piece of solid brass stock, like a drift pin. Or boat shafting. Have a machinist turn a end on it. I can't remember the thread size and pitch for DIN, but @cool_hardware52 does.

Or, use the business end of a junk DIN regulator...

Or just screw the junk first stage onto the valve and use a pipe wrench on the regulator body. You could use a yoke regulator if the valve is a convertible Pro-style by installing the conversion adapter first. A trashed first stage is probably less valuable/expensive than a new DIN plug!

This thread is a good example of DIY brainstorming over the Internet.

i have a big *ss strap wrench for that :

Or, get a piece of solid brass stock, like a drift pin. Or boat shafting. Have a machinist turn a end on it. I can't remember the thread size and pitch for DIN, but @cool_hardware52 does.

I actually did that with SS rod stock. It's 5/8 BSPP 14 TPI with a 55 degree cut. To make a long story short the tool marred one of my valves which they used to test it. The better machine shops here won't accept the job or are charging way too much. They said they need to buy the appropriate thread gauge and grind the 55 degree die. I have a brass din plug on hand. Will it be strong enough if brazed on brass rod stock? Thanks!

Narked at 90 has a valve tool. I've ordered things from them shipped to the US and haven't had any issues. I ran a quick quote and shipping to CA is £14.

This looks good right now but I am in the Philippines. It is a signed delivery service from Narced at 90 (probably via USPS). Do I have to personally sign for it or can my drop shipper sign it for me (as they usually do)? Thanks.

I don't see why they couldn't sign for it but can't answer for certain. If you email them to ask they usually get back pretty quickly.

The required go / nogo gauges are likely $200 or more, maybe much more. One could use thread wires, but they are a bit of a chore to use. A 55 degree thread mic would be *another* $300 item.

The tool is easy, Whitworth Threadform insert. https://www.kennametal.com/content/...679_MasterCat_stationary_threading_metric.pdf

Some valves, specifically OMS and Blue Steel don't have flats, so that tool (or a din plug with a handle welded on it) are the only way to remove the valve without scarring it...
Snip...

I just use a big adjustable wrench. No problems with damaged valves yet.

That explains it.
