Caps & Plugs Kits

In the hydraulic industry, cap and plug kits help prevent contamination from entering your hydraulic system during repairs or routine maintenance. You prevent contaminants from entering your system by capping your hydraulic hoses and plugging your hydraulic valves and hydraulic cylinder ports. Another benefit of a cap and plug kit is that it prevents hydraulic fluid spills, whether on your shop floor or in the back of your vehicle during transport. Lastly, there is no better way to identify threads than to thread onto the mating fitting. Each cap and plug kit has been designed to identify the male or female thread in a different series. Hose Box Cap & Plug kits are available in NPT (Pipe Thread), ORFS (Face Seal), JIC (37° Flare), and ORB (O-Ring Boss).
