The Hadron Molecular Series Polyurethane O-Ring is the ultimate pneumatic seal for the modern paintball marker. While flashy upgrades get all the attention, experienced players know that a smooth, reliable seal is what actually keeps you in the game. Even a tiny flaw in a standard rubber seal can cause bolt stick, velocity drops, or frustrating leaks that can cost you the match. At WC Marker, we carry these new Hadron seals to ensure your gear runs better than the day it came out of the box.
Engineered for high-performance drivetrains, this new addition to the Molecular Series is a major step up from basic seals. Designed specifically for high-stress friction points, the Hadron Polyurethane O-Ring formula offers better abrasion resistance and high-pressure stability than standard Buna. Whether you are playing speedball or hitting the woods, these paintball seals are built to handle the toughest conditions found across Canada.
