The 1050 piece Master-Tech kit contains 24 of the most common sized o-rings found in paintball equipment. O-rings are color coded by size and a color coded size chart is included on the box, eliminating the headache of matching up sizes. The MasterTech kit allows you to keep o-rings on hand to replace seals in a variety of paintball equipment including your marker, to your air/CO2 tank, and other accessories requiring o-rings. Kit includes o-rings sorted by size in individual compartments. Whether you’re grinding through rainy Sundays in a tournament or sliding through the mud while playing woodsball with your friends, your marker takes a beating on the field. We fire thousands of rounds and expect peak performance from our equipment at all times, but even the toughest and most well-engineered gear needs a tune-up from time to time. Fresh o-rings are the secret to a reliable marker that performs on the field for you when you need it most. Over time, constant cycling along with debris entering your marker wears down your seals. This leads to efficiency losses and leaks, and eventually your marker will not maintain enough pressure to cycle properly. Captain O-Ring’s o-ring rebuild kits offer an inexpensive and simple, yet professional-grade solution to keep your marker running in top shape day in and day out. The Science of the Seal: Captain O-Ring has proudly been offering our color coded o-rings kits since 2011. These kits feature proprietary, fully color-molded NBR70 O-Rings. We use the exact same high-performance NBR70 (Buna-N) material found in many of your marker's original factory seals. The only difference? We swap the standard carbon black toner for colored toners before before molding them to our stringent ISO3601 spec. The result is an o-ring kit that is color coded by size to make your rebuild and all future maintenance easier than ever. Material: BN70 / NBR70 (Buna-N) Performance: Same chemical and physical properties as black buna-n o-rings. Advantage: Color coding makes size identification and maintenance effortless.
