Rebuilding regs (PE, Ninja mostly) - sourcing decent UR orings + seals?

[mercpb]

I have a growing stack of NINJA & PE regs I'd like to get to rebuilding. I'll need some UR orings and I'd guess maybe a few pin valve/bonnet seals.

• Where are you guys getting decent 90UR orings?
• Any pro tips on what else I'll need / will never find replacements for / anything else?

Here's the shopping list based on charts/manuals I've found

PE TANK:	013-90UR	Piston large
	008-90UR	Piston small
	004-90UR	fill nipple
	Custom?	Pin valve seal

Ninja tank	012-90UR	Piston large (x2)
	008-90UR	Piston small
	006-90UR	Fill nipple. Cast ideally
	006 Teflon	Pin valve seal

The Oring Store.

I assume that's an obvious-question-gets-smarta$$ reply.

I've read and been advised that UR o-ring quality can differ greatly by source.

So if anyone has a real answer, or maybe just a link to "the o-ring store", thanks in advance

EDIT I'm a dummy that's a real site huh. thanks

The Oring Store is literally the name of the site.

They are a great source for o-rings of various size and material. There taffy is also quite tasty.

I order from The Oring Store all the time.

I LOLed at this because I had the exact same experience the first time someone recommended this site to me.

But as the others have said, the O-ring Store is indeed a great site. Their shipping costs are high, so for small orders, you can get better deals on eBay sometimes, but eBay o-rings have been hit and miss for me. Most of the time they're fine, but occasionally I've gotten some o-rings that are super old and break when I try to stretch them over something to install. That has never happened to me with The O-ring Store, though.

I've also been impressed with their tolerances. I use them exclusively for my SPAR valves, and the UR-90 o-rings that I use inside the SPAR have to be exactly the same size. If they're even a few thou over or undersize, they will either leak or bind up. I've gone through dozens of those o-rings, though, and they're always in spec.

And since you asked specifically about regs, I've used their o-rings for tank regs too. I have an old MacDev Push-Button LegionAir tank regulator that's been discontinued for years, so I can't get parts from the manufacturer anymore. But I've been using The O-ring Store o-rings for that reg piston, and they work great.

Reg seats are a different matter, unfortunately. They don't have those. But hopefully you can still get those from the manufacturer or maybe Doc.

The oring Store prices seem to have gotten a lot higher when looking at my old orders. I started to use global oring

As far as I know I was one of the first people here to start using the o ring store. Been using them for a long time at this point, I've recently started trying their colored buna rings, so far they are just as good as the normal blacks.

Those guys also have a paintball background so I've had a few odd paintball questions in the past that they have managed to help me out with.
