Hi,

I'll be taking a class on regulator servicing and am in the process of putting together my workbench.
I was wondering where you buy your o-rings? Looking to get started with one of those kits containing a bunch of o-rings of common sizes in a little box with compartments. I'll be using service kits for the 1st and 2nd stages so it's for other stuff like hoses, spgs, transmitters, etc.

Thanks! There are a couple of Grainger stores out in Brooklyn that can get you any o-ring you want. If they're like my local store here in Michigan they might need a few days to get them for you if not currently in stock. I know it can be a PITA to get around NYC. If you call them ahead of time maybe they'll check their inventory for you.

Ace Seal (in CA)
McMaster Carr
Precision Associates Inc
Marco Rubber

It's a juggling act between availability, the cost of the orings, minimum order quantity, and shipping charge.

McMaster is fastest, but shipping is costly and they only sell in 25's, 50's or 100's, depending upon the particular oring.

The O-ring Store, LLC allows small min quantities. Some orings are more expensive than McM; some are not. For BS and other non-US-standard orings, The Oring Store, LLC is my go-to.

For custom runs, PAI and Ace Seal have reasonable setup charges if they have the die.

Marco is way overpriced, but high quality.
Overseas mfrs have wildly varying quality, due (for example) to introduction of varying amounts of fillers like carbon black. If you want to prove that to yourself, just take a cheap digital luggage scale and pull on two identical orings from different mfrs until they break. You can see manufacturer quality variability quite simply with that simple test of tensile strength.
I simply do not buy from eBay, Amazon or AliExpress.
