Resources from Brown’s Gas Book 2 and for BG Book 2 Update
The Manufacturers listed here are specific to items and supplies needed for the projects in Brown’s Gas Book 2.
If you are looking for parts from manufacturers or suppliers that I use for several projects, see the ‘General Manufacturers’ page to find their contact information (I list only in one location so that I do not have to find all the locations when there is a change).
Though these manufacturers and suppliers are listed, be advised to ‘Let your fingers do the walking’. Try to locate various alternative suppliers and options. Doing this may save you a great deal of money. You’ll also learn a lot about the available options on components you are trying to locate. If you find good alternatives, let us know so we can tell other experimenters like yourself.
The Thomas Directory of Manufacturers is a great resource, available in most public libraries. You can go looking for a component, like a pressure switch and find pages of manufacturers. They are now available online.
Using Surplus suppliers you can often get great deals on components that are described well enough that you’ll be safe using them; like heavy duty relays, diodes, heat-sinks, capacitors, etc. Be careful with components that have ‘wetted parts’ like pressure switches and pressure gauges, because they could have material compatibility problems.
Also, remember that I wrote this book before there was an internet. Now you can look up these and many other suppliers online. Surf the internet to savings 🙂 If you are concerned with putting your credit card information online, use PayPal or a disposable credit card.
Direct Acting Pressure Switch:
Manufactured by Hobbs, sold by Stewart Warner
This is one component I suggest you buy new. It’s pretty vital.
For projects in BG Book 2, I prefer the 5000 series, similar to the 76578
factory set at 10 psi (it’s adjustable by the user)
Normally closed, open on pressure rise
two pole, screw terminals
Iron base, PTFE diaphram
After market modifications
1. Make a small hole in the adjustment chamber plug by cutting off the knob.
This prevents hydrogen, which will leak through/past the diaphram, from
building up pressure that skews the switch setpoint.
2. Resize (drill out) the gas orifice to 1/8″
Be VERY careful not to damage the internal components or
to allow metal filings into the switch. This prevents lye crystals from
eventually plugging the tiny orifice. Drill using progressively larger bits.
Plastic Pressure Relief Valves:
Part # Size Pressure Material Price Qty.
FC-MPR-25-1 1/4″ 10-80 PSI PVC $170.00
RVD 025 V-PV is $162.00
Either one will work OK for up to 2000 L/hr, I’ve tested them both.
I prefer the Plastomatic one because it withstood backfires better.
You need a little bracket and you’ll Tee into the BG out hose for maximum safety (don’t put it in the pressure gauge hose because the water in the mini-bubbler can freeze… And if venting at full volume you’ll push too much water out of the mini-bubbler, leaving the gauge and pressure switch unprotected.
Here is a video showing a test of the pressure relief (click).
I always get my experimental oil filled capacitors from surplus businesses. Saves me bunches of money. I only start buying ‘commercial’ capacitors when I make a production run of machines, because then everything must match. With one-off projects it doesn’t matter if the components don’t match, just so they meet the important specs.
Try this place (click) The larger capacitors are at the end of the list.
You can also pick up your heat sinks and a lot of other components at such surplus places online.
Main Electronic Relay:
I’ve used several over the years and have to say I’m really impressed with Opto 22 (click) and that’s where I’d recommend you buy your solid state relay (SSR).
For my electrolyzers I like to use the M5000 from Madison (click). I know of several others and you can even find good alternatives on eBay.
I like to use an acetylene torch handle check valve from Air Liquide. I also buy the fittings to adapt it to a 1/4″ inline hose application. I then use it in all my electrolyzers for water filling.
WES-CV8L: Check Valve,Torch,West.,Fuel Gases,Male B to Female B Nut, LH,CGA023
The key to these inexpensive check valves is to check them for leakage right away.
I find about 10% of them leak right from the factory. I check them by blowing
backward through them with a hose attached into a glass of water. If you see even
one bubble, the check valve is bad. They will replace defective ones.
WES-8: 2 of Nut,Hose,Western,Fuel Gas,B,LH
WES-17: 2 of Nipple,Hose,Barbed,Western,6MM 1/4″barbed to Male B
I used a NF25S-2B/U from Weiss Instruments, Inc. It is a liquid filled design (higher quality and dust free) but with no liquid in it (because liquid impedes the fast operation needed if there is an explosion/implosion).
