HNBR Master Oring Kit Recommendations

[Lotus]

So I'm putting a few autocockers back together and rebuilding all of the components (LPR, HPR, 3-way, RAM, lower tube, etc) and I'm looking for a good quality master o-ring kit.I saw autococokerparts.com's master o-ring kit, and it has those shitty colored o-rings that I don't want to touch with a 10 foot pole. I'd much rather have something I can put in my gun and not worry about for years. Regular Buna orings would be fine, but part of me just thinks it'd be cool to use HNBR since those things last so long, and I don't want to have to do this again anytime soon.

Is there a master o-ring kit I can use? The last time I did this for my PM8, I just went to https://www.theoringstore.com/store/...&cPath=367_123 and bought several of the sizes I needed for that marker and ended up building my own kit, but that was definitely not ideal from a cost perspective. One thing that would help is if I knew all the sizes I needed for autocockers with standard WGP internals (9/16th valve, adjustable LPR/HPR, orracle 3-way, standard ram).

Ive been wanting to build an autococker o-ring kit for a while. Buy bulk quantity and make kits for everyone here ... So definitely interested in getting a master size list.

As far as hnbr ... Why not go straight for epdm orings ... The cost is about the same and they will be even better ...
fkm would also be a good material (very similar to hnbr but more chemical resistant)

I'm going to stick to HNBR. EPDM o-rings don't like mineral oil, which is a common paintball lube, and I don't know how long Viton orings last. HNBR seems ideal for my purpose as they're supposed to last basically forever, which is what I'm looking for.

Going by https://www.ebay.com/itm/Oringmonkey...sAAOSw6NVeE1Bz, it looks like I need:
003, 006, 008, 010, 011, 012, 013, 015, 016, 018, 112, 113.

I think 003 are the 3-way orings so I need more of them, 006 looks to be the ram o-rings. I wonder what the outer o-rings are in an Orracle 3-way? Either way, this looks to be a great start and I might end up just buying individual o-rings in bulk sizes from www.theoringstore.com/store.

I find FKM tears easily - not lengthwise, but in the direction of the hoop, it turns to a bundle of string.

EPDM is ok, but I'll take HNBR or even standard buna over it in a paintball application. I turn towards EPDM for hot steam or things like that. Around oils, NBR or HNBR are superior.

I like theoringstore.com.

Edit: looks like I'm now just confirming your response. Beat me to it.

Thanks for the input, I'm used to deal with extremely harsh oxygen/ozone environment ...

And thanks for the list/link.

I can put an hnbr kit together and source it from my supplier if there is interest.

As others have already stated, I will agree that Buna or HBNR and theoringstore.com are the ways to go. Just make a list and put it together yourself. Walmart and Michaels craft areas have better selections on storage cases for great prices as well. While you're at it, it doesn't hurt to stock up on all sizes 003-021 in both 70 and 90 duro, as well as 110-113 in both durometers as well. I have had some success in using 50 duro bunas in some LP applications as well, but that expansion can wait until you're doing a restock of the more standard stuff that you actually use. Also, grab some 3x1mm rings if you plan on working on Inception or Empire 3-ways. There are some oddball "proprietary" seals in some of the cocker pneus, especially 3-ways, but a lot of those can be substituted with a similar sized standard o-ring.

Alrighty. Order placed. I bought about ~450 o-rings for around $50. Should be good for all my markers for a really long time. Next up: an o-ring pick (probably a brass dental tool) and a storage container.
