Hydraulic Caps, Plugs & Clamps
Cut grit, leaks and cleanup when lines are uncoupled or serviced. Kimball Midwest's stock of caps, plugs and universal service plugs keep coupler faces and hoses sealed against dirt, nicks and moisture so fittings last longer and stay ready to connect. Add a break-away clamp to mount 1/2" couplers for one-hand hookups and safer disconnects. Choose series-specific caps and plugs for a tight fit.
