Frequently Asked Questions
The plug uses 1/4"-18 NPT male threads for sealing unused hydraulic/fluid ports.
Yes. It is a headless style plug designed to sit low and flush, helping in tight manifold areas.
It appears in GH-series parts/OEM kit diagrams, including GH733, GH833, GH933, GH2570, and GH5040. Always verify against your unit’s parts list for exact placement and quantity.
Use of non-OEM plugs is not recommended. OEM parts help ensure fit, corrosion resistance, and correct sealing geometry for high-pressure systems.
Clean threads thoroughly, apply a compatible thread sealant sparingly, torque appropriately, and verify for leaks after pressurizing the system.
