Benefits & Tips

• Practical uses: seal carburetor or manifold openings during maintenance, cap hoses or pipelines to prevent contamination when disassembling components, and protect unconnected ports from dust when the system is idle.
• Easy selection: six common sizes ensure a near-perfect fit for a variety of components. Use the included plastic case to keep sizes sorted and ready.
• Pro tips: clean the surfaces before inserting a cap, choose the closest matching size for the seal, and store caps in the case to prevent loss and deformation. For smoother insertion in tight fits, a light touch of silicone-safe lubricant can help.
