Pneumatic Hose Plugs | Quick-Insert Sealing Caps | 4-16mm Multi-Size Kit (10-Pack)

This 10PCS KQ2R/PGJ Pneumatic Joint Variable Diameter Pipe Plug Cap set provides a versatile and reliable sealing solution for pneumatic systems. The quick-insertion design ensures a secure, airtight seal on multiple hose diameters from 4mm to 16mm, preventing air leaks and protecting internal components from dust and moisture during maintenance or storage. Features and Benefits - Variable Diameter Design - Each plug seals a range of sizes (e.g., 4-6mm, 8-10mm, etc.), reducing the number of individual parts needed and simplifying inventory. - Quick Insertion Sealing - The push-to-fit design allows for fast, tool-free installation and removal, saving time on the job site or in the workshop. - PU Material Construction - Made from durable polyurethane, these plugs offer excellent resistance to abrasion, aging, and typical pneumatic system pressures. - 10-Piece Assortment - The set includes multiple plugs covering 4, 6, 8, 10, 12, 14, and 16mm diameters, providing a complete solution for common pneumatic hose sizes. - Positive Seal Retention - The plug's design grips the hose ID securely to maintain a reliable seal, preventing accidental dislodgement and protecting sensitive valves and fittings. Applications - Pneumatic System Maintenance - Seal open hose ends during repair or component replacement to prevent contamination from entering the air lines. - Workshop Organization - Cap unused ports on manifolds, tools, or machinery to keep them clean and ready for future connection. - Transportation and Storage - Protect pneumatic equipment and air tool connections from dust, debris, and moisture when not in use or in transit. - Leak Testing Preparation - Use plugs to isolate sections of a pneumatic circuit for efficient pressure testing and leak diagnosis.
