High Performance O-Ring Kit

Keep your Tuff Jug flowing and sealing properly with this 5-piece replacement o-ring kit. Designed to complete the complete o-ring replacement for either the Ripper Cap or Auto Stop Spout. Certain blends and higher octane levels can occasionally cause swelling in standard Viton® o-rings, leading to performance or sealing issues. This kit is the solution and provides long-term durability when running methanol, race, or high-octane applications.
