The Multiquip 959403790 is a genuine OEM 1/4-NPT Locknut Teflon Sealed Special designed for MVC-series plate compactors including MVC70E, MVC70EW, MVC64VH, MVC64VHW, MVC82VH, MVC82VHW, MVCE64V, and MVCe82VBW models. As a direct Multiquip OEM part, 959403790 is manufactured to the same specification as the original component, ensuring a correct, leak-free connection at the fitting point. Sourced directly through authorized distribution, this locknut is the recommended service replacement whenever the original shows wear, thread damage, or seal degradation.
Key Features
- Teflon-Sealed Thread Integrity — The integrated Teflon seal provides consistent thread-sealing performance at the 1/4-NPT connection, preventing fluid or pressure leaks at the fitting.
- Genuine OEM Part — Manufactured by Multiquip to the original production specification, so material grade, thread pitch, and sealing compound match what left the factory.
- Broad MVC-Series Compatibility — Confirmed fitment across MVC70E, MVC70EW, MVC64VH, MVC64VHW, MVC82VH, MVC82VHW, MVCE64V, and MVCe82VBW plate compactors.
- Secure Locking Design — The locknut format resists loosening under vibration, which is critical on plate compactors where continuous high-frequency vibration can work standard fittings loose over time.
- Direct Service Replacement — Installs in the same position as the original with no modification to surrounding hardware, keeping service time short.
A 1/4-NPT locknut with a Teflon seal is used at threaded pipe fittings to lock a connection in place while simultaneously preventing fluid or air from escaping past the threads. On plate compactors, these fittings are commonly found in water tank, fuel, or hydraulic line connections where both a secure lock and a leak-proof seal are required. When this part becomes damaged or the Teflon seal deteriorates, the connection can weep fluid or allow air ingestion, leading to inconsistent system pressure and potential damage to downstream components. Replacing it with the correct OEM-specified locknut restores a fully sealed, vibration-resistant connection.
