Key Features
- Genuine OEM Hardware Grade — Manufactured to the exact thread specification and material standard as the original plug fitting, ensuring a secure, leak-free seal in hydraulic and fluid-routing applications.
- Direct-Thread Installation — The 1/4MP square head drive profile installs directly into the original port without adapters or thread chasing, matching the factory-installed fitting geometry.
- Broad Cross-Equipment Fitment — Compatible with MD105, STXDF, HHNG5, MVH158GH, MRH800GS, JWN24HTCSL, HHN31V, HTXG6DF, LT6K, LT6KV, and WSHE-A series equipment.
- Fluid System Integrity — A correctly seated plug fitting prevents fluid loss and contamination ingress at unused or capped ports, keeping hydraulic and fluid circuits operating at designed pressure.
- Corrosion-Resistant Construction — Built to withstand the moisture, debris, and mechanical vibration typical of construction site environments across multiple machine types.
A plug fitting seals off an unused or temporarily capped port in a hydraulic, fuel, or fluid system. By closing the port, it prevents fluid loss, blocks contamination from entering the circuit, and maintains system pressure where it is needed. When a plug fitting becomes damaged, corroded, or develops a compromised thread engagement, it can cause fluid leaks that reduce system efficiency or allow debris to enter sensitive components — making prompt replacement with a correctly sized OEM fitting essential to system reliability.
