Sources for Fusor Related Items

Post by Frank Sanns » Sun Apr 02, 2017 6:05 pm

Most people look to eBay and other sources to scrounge for their fusor items. I thought it may be helpful to create a sticky here in the trading post for the new people so they know where to find some of the more common items.

Feel free to add to the list and I will incorporate ones that I think are most appropriate. This is not so much for manufacturers but rather distributors of things useful for a fusor.

I will start by adding LDS as they have served many of us here on very well over the years.

Vacuum fittings, flanges, adapters, pumps etc.:

LDS Vacuum Shopper

Ceramic stalks, HDPE moderator, teflon, etc.:

Chambers, everything UHV:

Duniway stockroom is another good place for vacuum products. They offer several types of (rebuilt) pumps and other vacuum hardware.

They also have excellent customer service. ... 2749.l2754

LDS is particularly notable for their compression ports, which are very expensive from other sources.

Notably, Duniway has nicer KF clamps than most vendors. has a variety of feedthroughs including some highly specialized ones, ones with loads and loads of pins, etc. As well as other metal-glass sealed stuff.

Amazon has some basic KF fittings, Swagelok knockoffs, and a few other things. Not much, and rarely cheap, but sometimes worth attention and you can get fast shipping cheaply. Also, the cheapest way to buy small amounts of Macor ceramic is Amazon. Most of my KF clamps and centering rings are from Amazon

McMaster is very useful for O-rings, gaskets, and large-diameter short-length Pyrex tubes for demo fusor chambers. They also sell conflat gaskets in single quantities. Unfortunately they are quite expensive for many things -- but often cheaper compared to umpteen different shipping charges.

Ideal vacuum products ( has a VERY broad selection of vacuum stuff including mech pump rebuild kits. They seem to be cheaper for some items and have a better selection of brass KF fittings. Have to say I'm intrigued by their Ideal Vacuum Cube module chamber but they are dear.

Ted Pella ( is mostly a biological microscopy store, but they sell a bunch of vacuum stuff related to electron microscopy and sample prep. I have never ordered from them.

You can buy inexpensive mech pump oil from the auto parts store. I don't know how it compares, but I get to 8 microns just fine with my blanked-off pump.

They have every size and material imaginable. Good for weird sizes, custom apps, and rebuilding ancient mystery equipment like my 1/2 century old Edwards leak valve. Minimum quantities are usually 1 to 6 of each, but at pennies a piece, I usually buy the next sizes above and below the size I think I need and use the one that fits best. Shipping is usually 5 to 7 dollars. My orders are usually about $10 to get everything that I need.
If your experiment needs statistics, you ought to have done a better experiment.

BMI Surplus carries vacuum parts, feedthroughs, etc.
Because they are surplus, availability and pricing changes. But, I've found some good deals there.

I have used Ted Pella a bit for their fabulous line of graphite applications. ian supplied their URL above. The one below leads to their conductive coatings. ... htm#_16058

They have graphite pastes and thick liquid applications using a brush as well as thin, watery applications using a brush, but more importantly, spray cans (aerodaq - G) for graphite application.

These coatings are often termed a form of acquedaq. (conductive coating used for shielding or electrostatically conductive surfaces.)

I use it for manufacture of conductive shield coating of thin diaphrams for ion cambers and mica windowed GM detectors as well as outer shell GM countings on glass.
Graphite coatings are fine for use as light weight capacitive surfaces of electrostatic motors and other experiments in this area, etc.

Note: the graphite coatings have effectively zero resistance to electrostatic voltages, but for current carrying apps the very expensive thick silver coatings are to be preferred.

+1 for James at Global Rare Gasses. Two emails and a paypal payment was all it took. Thanks for the tip. This forum never ceases.
