O-rings

[pirhana92]

Stupid question but where does everyone get their o-rings for paintball? Is there a specific kind you have to use for paintball or can I go to harbor freight and buy an assortment?

[Jonnydread]

I have gotten mine from the o-ring store for a while, but in a pinch Harbor Freight/Ace/etc. should have o-rings that will do. Just make sure you're getting the correct material for the usage.

I buy from the oring store. You can sort by size, material and hardness so you can get the exact specs you need. Stay away from the coloured kits as they don't last.

I bought a kit from HF in one of those small clear boxes of different hardware they sell and the orings all had an oblong cross section and wouldn't seal. They also weren't labeled properly. Now I just use them for tension on threads and bumpers.

Most kits you buy from stores aren't going to be super useful for paintball because they're meant for hydraulics and most of the orings will be way too big.

Pretty much answered my question while I was posting it lol

[Psycho91]

I was thinking about this the other day, is there a decently priced assorted kit that any of yall have used that has all the major sized orings we use

hell idk the last time I actually bought a rebuild kit for a marker I usually just hit the plumbing section in Lowes and hope I find what I need, I think iv ordered specific orings from oring money before, I think it was them

I've had good luck with this 450 piece kit I bought from https://www.orings-online.net.

I need to buy a new master kit, thanks for the link/reminder!

[pirhana92]

Would this be a good general kit for like bolts and other misc parts that take o-rings?

[appleguy]

Yeah, this kit is perfect for that.

I heard people say this but also that it mainly comes from poor quality rings. A little over a year ago I decided to try colored rings from the o ring store, so far so good, I haven't noticed anything different from the black ones

For the op, for the most part, paintball o rings are
AS568 (basically the "class")
buna (the material)
70 durometer (the hardness)

Sometimes you will need polyurethane rings
Sometimes 90 durometer

Just depends on the situation

For the most part though, if you want to put together a kit, I suggest sizes 003-022 in buna 70. You can get pretty far with that. That's what I have had for years and I only recently put together a selection of metric sizes to go further

This is great to know. Thank you.

I have ended up with a bunch of colour o/ring kits from various sources and haven’t had issues with them. What kills me are the really small o-rings below the standard ones, like the 004 o-ring I need for the valve stem of the NME I’m trying to rebuild. Ended up finding them Amazon and will get them in a reasonable timeframe.

I need to sit down and do an inventory and order a bunch of o-rings so I have them on hand, specially the ones that fit in the macro fittings.

Standard macro orings are 010/70. There are ones from SP that take a larger oring though.

I save things like o-rings from all of my projects, maintenance and paintball purchases. They all get thrown in a box and occasionally I get motivated and sort them out by size/material. I rarely have to buy an o-ring specifically for paintball but if I do I buy them in bulk lots (and throw the excess in the same box). The O-Ring store is one good source but have also bought some from Capt. O-ring and FLASC on-line and not had issues but many times I just take an example to a pneumatic shop locally and get them to match them.

I had recently bought a seal kit, but all the o-rings are Buna... owners manual indicates some of then need to be urethane, so I got those from captain o-ring...

Try with the buna. Just because the manual specified polyurethane doesn't mean buna won't work

I've only come across one situation with a dye marker that using buna in place of a polyurethane made it so the marker wouldn't work (technically it still shot but leaked). That situation is also why I don't like dye markers past 2010. The tolerances became way too tight

I've bought a captain oring master kit. So far so good. The little size chart they include is a life saver. For the 40 or so bucks I spent I consider it well spent.
Now if I could find a urethane oring kit that would be magic.

Theoringstore.com is great. McMaster works in a pinch.

It's nice to be able to pick compound, and they have a software that'll scan a ring and ID it by size. (Haven't tried it yet...)

What!?!? I want to try this where is it?

Yeah don't go buy another full kit. Get on theoringstore.com and just order whatever size you need in whatever quantity. It's also great for replenishing the kit you have since inevitably you'll run out of I've size before anything else

I'm exploring some other options. Theoringstore has moved their minimum quantities to 100 rings which for a lot of what I order is fine but I don't need that many 1x4mm metrics and they have a few metric rings that are crazy expensive so I don't want to pay $30 for one size

Checking out globaloring.com the price on rings is good but trying to figure out shipping as the only options it's giving me are $138+ for second day air or faster.

Anyone have a good source for tank rings? 015 urethane 90 duro. Captain o ring has good packs of them but I'd rather be able to get them from the same place I'm getting the rest of my rings rather than having to place a separate order. Captain o ring is around 10 cents each

Orings-Online.net sells singles. Or loosies, for anyone who frequents bodegas. Both 1x4mm and 015 urethane 90 duro are 25¢ each. Quantity deals start at 50. Been getting o-rings from there for several years.
