Eaton -2673 Hydraulic Hose Coupler Dust Plug 3/8 Inch

Product Description

The EATON -2673 is a brass hydraulic hose coupler dust plug designed to seal and protect the open end of a hydraulic coupler when the line is disconnected. Constructed from brass, it provides corrosion resistance and durability in demanding fluid-power environments. The plug fits a 3/8-inch hose diameter and is used to prevent contamination from dirt, debris, and moisture from entering the coupler body during storage, transport, or service intervals. Licensed hydraulic technicians and fluid-power service professionals install these plugs as standard maintenance practice to maintain system cleanliness and extend coupler service life.

This dust plug is suited for use on hydraulic hose couplers in mobile equipment, industrial machinery, and stationary hydraulic systems where 3/8-inch coupler bodies are used. It is appropriate for both shop-floor maintenance scenarios and field service situations where lines are frequently connected and disconnected. Sold in a package quantity of 10, the -2673 is practical for stocking in service trucks or shop supply bins where multiple connections may need to be capped at once.

Installation Notes

Hydraulic system service should be performed by qualified fluid-power technicians. Before removing any hydraulic line, relieve all system pressure and allow the system to depressurize fully before handling couplers. Thread the dust plug onto the coupler body by hand until snug, taking care not to cross-thread brass fittings. Inspect the plug for damage before each use to ensure a proper contamination seal.
