O-Ring Rebuild Kit Compatible with DYE Proto SLG/UL Markers – Color-Coded DLX 300+ O-Rings & Storage Case

Keep your Dye Proto SLG / UL marker performing at its best with the Flasc Paintball O‑Ring Rebuild Kit. This complete maintenance kit includes everything needed to rebuild your marker many times, giving you long‑term reliability and consistent performance on the field. Each o‑ring is color‑coded, making identification fast and frustration‑free. Whether you’re doing a full teardown at home or a quick repair between games, you can instantly match the correct size without charts or measuring tools. All o‑rings in this kit are made from high‑quality NBR in the proper hardness rating for your markers operating pressures. NBR provides excellent resistance to wear, swelling, and pressure cycling, making it ideal for both CO₂ and HPA setups. Every kit is assembled and quality‑checked right here in Canada, ensuring consistent standards and dependable performance for Canadian players. The included storage case keeps everything organized and protected, making this an essential upgrade for any paintball equipment owner who wants smoother operation, fewer leaks, and maximum uptime. Maintenance Tip For best results, lubricate o‑rings lightly during installation using a paintball‑safe lubricant. A small amount of oil or grease helps extend service life, improves sealing performance, and reduces wear during CO₂ or HPA use. We recommend Flasc Paintball Marker Oil and Flasc Paintball SMG Grease, both formulated for paintball markers and fully compatible with marker internals and o‑ring materials.
