It is practically common knowledge that O-rings make great gaskets as they rock at keeping joints watertight and airtight. They are so simple, so basic in design. Essentially they are just these donut shaped rings of varying diameters and thicknesses, and they are usually made of rubber or some such material with similar sealing properties, like buna or urethane. It is this simplicity in design that makes O-rings incredibly versatile.
With such “important” uses in plumbing, in cars and motorcycles, it seems a bit surprising that one of its popular uses involve recreational activities such as paintball games. O-rings are absolute essentials in paintball guns because they keep the joints airtight. So air can be compressed efficiently so it can propel the paintball ammo effectively.
Because the O-rings play such a vital role, replacing them regularly is a key part of paintball gun maintenance. The moment you see warping and cracking in a rubber ring, then it is time for it to go. Replacing an O-ring is a cinch too, just slide the old one off and the new one in.
Here are a couple of things to keep in mind:
1. Before you can slide an O-ring off your gun, you’ve got to get a good hold of it. Usually this involves using a sharp metal object to get between the ring and the gun in order to lift the ring up and get a grip on it. But while doing this, you should try not to scratch the gun. That wouldn’t look good, and might provide an avenue for air to escape.
2. Make sure your replacement ring is the right size. It must fit snugly in order to provide the desired sealing effect.
