Lainie,
You are probably going to have to have these molded to fit your application 
(tooling is fairly inexpensive), but you may find a vendor who has a stock 
size that works for you.

I've had good results in the past with dipped style boots from:

Harman Corp.
360 South St.
Rochester, MI
810-651-4477

There are certainly other vendors for this same style material, and there 
are other molding techniques/materials as well (the material/tooling 
charges/volume needed will have a large impact on the overall cost 
effectiveness of the masking).

The only caveat I would offer is to obtain multiple samples of the 
materials (there are several, Hi-temp, etc.), and coat them several times, 
before ordering production, as I had trouble with one particular boot 
material/conformal coating combination causing the coating to remain very 
tacky on the boot, thus leaving them very difficult to handle upon 
removal/reinstallation.

Hi All,
Does anyone know anything about "standard" masking rubber boots which 
can be placed over connectors, test points, etc. and effectively 
withstand spray conformal coating?  I'm trying to find a supplier...
-----Thanks in advance!
