Official Macdev Orings Thread

There have been a ton of threads recently about orings so I figured it may be a good idea to have it all in one place for people to ask their questions and get their answers.

I have compiled a bunch of info from all over the forums and internet.


Oring Materials

Buna - Also known as Buna-N, Buna-T, NBR, Nitrile. They are all made of the same material, Butadiene Nitrile. These are the typical orings that come on almost every paintball gun. They are the cheapest, the most common and come in black color. The Durometer hardness is A70. If you are unsure what material to buy this is the default material to go to.

Urethane - Orings of this material are traditionally higher quality than Buna. They come in many different durometers. They are usually a clearish color. Harder durometers like a A90 durometer urethane orings are often solid white instead of being clear colored.

Viton® fluoroelastomer - These are slightly harder and slightly more durable orings from the Buna. Durometer hardness is typically A75. They are usually black but can be a greyish or brownish color.

HNBR - Also known as High-Temperature Buna-N (Hydrogenated Nitrile Butadiene Rubber). These are the green orings you see. They are similar to Buna, except the material is hydrogenized (saturated with hydrogen to improve resistance to heat and ozone). They should hold up longer than urethane or buna, while maintaining the same durometer as the Buna rings.


Oring Shapes

Round - Typical orings you are used to seeing on paintball guns. Cross section is round in shape.



X ring- Also known as Quad ring, Quattro Seal, Double Seal. These are special o-rings made in an "x" cross section shape for a double sealing surface. The idea is that the quad ring won't be able to twist and bend when the part moves since they aren't circular. They also should allow for lighter seals since the surface of the quad-ring sealing against the part is smaller. This should allow for less pressure required to move the part though this may be extremely negligible in paintball gun.

There are only certain places you would want to install an x ring. You would want to replace any oring that has movement over it, either when the oring is stationary but something slides over it or when the oring is on something that slides. You also want to make sure that the x ring has constant contact with a surface. You do not want an x ring in an area that goes into and out of contact with something as the x shape of the ring can get caught and pulled off. When using quad rings you must experiment with them. They may leak or cause other issues. They may or may not work in all applications. You will need to try and see if your results are positive.

The Droid manual does not give any sizes of the orings for the drivetrain like all the other manuals. How do they expect you to replace o rings? I will look into it and try to figure it out though.

If you guys are ordering new rings I would recommend oringsusa.com, i just placed my second order with them and they ship within 1 business day of ordering and have a mcmaster size selection.

Viton rings are 6-8 cents each, x-rings are 22-24 cents, regular buna are cheap and urethane aren't bad either(although their urethanes are hard as a rock) There shipping prices aren't great but for 55 viton and xrings my total was 9.80 before shipping(7.50)

Yes I agree this should be in the stickies for sure.

Regarding the X-rings...which o-rings on a Clone VX would benefit being changed to X-rings? Bolt switch / bolt keg inner? Powertube tip? After reading some people's success with these, I want to order some and just want to make sure I swap the appropriate ones.

I do not own a Clone VX (yet, it is in the mail ) so I am not super familiar with the drivetrain in it but I do have a Drone DX so I'll try to talk about both.

As far as X rings, you can replace any oring that has movement, both when the oring is stationary but something slides over it or when the oring is on something that moves. Also you want to make sure that is an oring that has constant contact. You do not want to replace it with an X ring if the item goes into and out of contact with something as the X shape of the oring can get caught and get pulled off or something similar.

On a Macdev Drone DX you would replace the Keg Inner Oring (017) and the Bolt Switch Orings (016). You generally would not do the Valve Oring (014) because that slides into and out of the bolt. You could try and have good luck or it might not work well.

On a Macdev Clone VX you would replace the Bolt Keg Inner (017) and Bolt Swicth (016) for sure. I am not sure if the powertube tip oring goes into and out of the bolt or not but that is a possibility as well.

I placed an order the other day for a bunch of 011's, 016's, and 017's. I am going to replace the bolt switch and bolt keg inner for sure. I have to double check the power tube tip's 011 to see if it does stay in constant contact with metal, or if the bolt slides far enough forward for that small recess in the middle of the bolt to cross over where the 011 contacts.

So 016 and 017 definitely, and depending on testing, the 011. I will post back with my impressions once they arrive and I have a chance to test things out. The Clone only has about 3 cases through it right now so it's not exactly broken in yet, but I'm still hoping to see some positive results.

I agree this needs to be stickied

Just an update with my own Clone...I got my quad o-rings in and have swapped the bolt switch and bolt keg inner rings out. I verified that the powertube tip is not a candidate for a quad since it crosses into the middle section of the bolt as it cycles and is not always in constant contact with metal due to the center of the bolt having the metal raised up in small section of the inside of it towards the middle.

I haven't actually played with it since the swap though so I can't give impressions on efficiency or smoothness yet with them in there, but based on what some others have said both should improve.
