Valve rebuild?

[Lvmymag]

Does someone on here or anywhere sell rebuild kits with all the o-rings for classic valves? And are classic valves the same as mini and micro valves? I just picked up some valves that have been sitting for a long time and wanted to see if I could get em up and running. Thanks!

Tunamart or Airgun Designs.

Any yes, they're the same.

Awesome thanks!!! By chance the kits that tuna sells are they full rebuilds or just a handfull of orings and bits

They're a "rebuild kit," the same as what AGD sells, containing a set amount of each o-ring based upon what usually needs to be replaced the most. For a list of what sizes of o-rings and how many are included in a rebuild kit, check out the O-Ring Size Chart thread.

I just read the post about o-ring sizes thanks for the help. Fingers crossed I'll have these valves up and working soon thanks again!

also, ebay for $20 shipped, and at ansgear. ebay is the cheapest, then probably ansgear. agd charges at least $6 for shipping; i don't know what tuna charges.

Just paid 6 in shipping for a bunch of small stuff from Tuna.

Overall his prices for product have always been great though. And if your needing multi kits that would be the rout I would take.

EBay is fine. Just make sure what you are buying. Buna orings work. But not nearly as reliable as urethane.

Yeah, and even if you're paying something just mildly cheaper on eBay for Buna o-rings, you're getting ripped off. Buna o-rings are dirt cheap, as in literally pennies per o-ring. So don't get ripped off by the eBay "rebuild kits". Urethane o-rings are much more durable and just plain cost more. You get what you pay for with that comparison.

It's also good to keep things in house.

Tuna is one of the AGD good guys. I've met him personally, and done business with him. He will take great care of you.

ANS is a massive company. I've never met them personally. Could I buy mag stuff from them? Sure. But I don't, because I'd much rather give the business to him than to them.

you guys misunderstand, you can buy genuine automag rebuild kits (not buna kits), new in box, for $20 shipped, on ebay.

that's fine, just throwing another option out there. could come in handy if you need more than just 'mag parts, you know? save on shipping to buy in one place, etc.

Buna orings can work just as well as urethane orings as long as they are the same durometer as the urethane ones they are replacing and have the same tolerance specifications AND are only being used with air. Buna does not work as well with CO2.

I agree 100% that they CAN. Under certain circumstances. My track record with them in general withing my real job though is. There tollerences suck. And they are soft rubbery and squishy to conform and make up for crappy tollerences. So when it comes down to it its not worth a potential 5 dollars saved to use a potentially ploblematic part. Also buna twist lock Orings are a total pain in the butt. They are streatchy and get hung on every crevice in my RT or minimag when putting a barrel on.

They are only soft and rubbery if they are not the proper durometer rating. Crappy tolerances are a result of chosing general purpose orings. You can get crappy urethane orings as well. A buna oring with the exact same specs as a urethane oring will perform exactly the same. The only thing that is different between the two with the same specs is the chemical resistance.

It always pays to make sure you are using good quality orings with the proper tolerance specs, especially in a mag where tolerances matter.

Athomas. I agree with you totally. But your details you point out are exactly what I was emplying by saying "under the right circumstances". I wasn't gonna get real detailed or technical because the general public wouldn't know the differences if they were right in front of them. A Oring is a Oring to most. And in general. You do not walk in to a parts store and find the proper buna Orings. I have my doubts that the eBay kits are the "proper" Orings either. HOWEVER I do not know that for a fact. I choose an actual OEM parts kit. Because it is less likely to have parts with issues. And for no more money than I could save the greater potential headache isn't worth it. Its not like these mags eat a ton of Orings...... unless you get liquid co2 in the valve. OH the good old days.
