Anyone know where to get Urethane O-rings (other than the tank o-rings) for less than a fortune pricing? I am putting together a bulk repair kit and I am stuck trying to find the Urethane ones... if McMasters was a little more reasonable on them... :(

Thanks in advance everyone!!!

McMasters is the cheapest that you'll find.

Even for Urethane ones?

I haven't looked much of anywhere else, but I'd assume so... If Urethane's so expensive for you, why not just get Buna-N's? :confused:

Because the Urethane is what is in there and I don't want to change it.


If nobody knows of anything else, I am just going to get some from McMasters...even though one is almost $15 just for 10...

Thanks OIM! I am on there now... but they have Buna and Viton material o-rings. Any idea if Viton is comparable to Urethane?

The last oring order I had was just over 1000 rings for less than $50, I wanna say it was more like $30ish. I got that from Enco.

I just made an order through McMaster's and bought 1,100 O-rings for approximately $60...

Mudder, it's www.use-enco.com ;) That's a pretty decent price for that quantity... If you want to make money back, you could always try selling kits for other owners.

As far as the o-rings for the A1....The only problem is you can't get the triangular o-ring anywhere but from WDP...they've got the market on that one!!!

If VITON is as good or better than Urethane, I am gonna buy them...they are more expensive than Buna...so that must mean they are better... :dodgy:

Seriously, what's wrong with Buna? I've never had a major problem with them more than I would have had with urethane given the same circumstances...


I think that Viton's about the same as urethane, but has a slightly different temperature range.

Aren't Buna a little softer and a lesser grade material? Like I said, I just want to keep the parts in my A1 as close to stock as possible....

Not really... If they're the same durometer (measure of hardness) how can they be much softer? :confused: They're cheaper than urethane by a BUNDLE, and as I said before, I've never had a problem with them as compared to a urethane.

I heard from a fairly reputable source buna orings swell if exposed to co2, this kinda explains why some worn out guns have a warm up time where they leak for a minute and then shut up. However on an angel I highly doubt you are running co anyways.

Nope... I haven't used Co2 since I stepped up to my PM's. Thanks for the info though!

I am checking on this Viton material...hopefully I'll get a response soon. My rings from McMasters came today... only took two days!!! :)

Thats what I was gonna do with all those oring I have for EM1s. IIRC I have enough for like 25 full rebuilds. I was only gonna try to make a buck off of a kit. Something to make up for a few minutes of my time but not rape Emmie owners on the price.

In my '08 Enco catalog, the hardness on Buna is 70 +/- 5 & the Vition 75 +/-5 I dont really think the is a whole bunch to worry about. Plus if you care for your marker you could make rings last a while.
