The Multiquip 19594 Brass Fitting 1/4 MP-5 Tube Nut is a genuine OEM hydraulic line fitting designed for HTH-Series hydrostatic ride-on trowels. As a direct OEM replacement, this fitting is manufactured to the exact material grade and thread specification required for proper hydraulic system integrity on these machines. Sourced directly from Multiquip, part 19594 ensures a correct, leak-free connection in the hydraulic circuit where the original fitting was installed. If you are servicing an HTH-Series ride-on trowel, this is the factory-matched component for the job.
Key Features
- Brass Construction for Hydraulic Compatibility — Manufactured from brass to resist corrosion and withstand the hydraulic fluid pressures typical of HTH-Series trowel systems.
- 1/4 MP-5 Thread Specification — Sized and threaded to the exact 1/4 MP-5 tube nut standard, ensuring a clean, secure connection without leaks at the fitting joint.
- Direct OEM Replacement — Matches the original Multiquip 19594 fitting exactly, threading directly into the hydraulic line position without adaptation or rework.
- HTH-Series Hydrostatic Ride-On Trowel Fitment — Confirmed fit for HTH-Series machines, keeping your hydraulic system operating to the spec these trowels were built around.
- Hydraulic System Integrity — A failed or loose fitting can cause hydraulic fluid loss and loss of blade pitch or drive control; replacing with a correct OEM fitting restores full system pressure and function.
A hydraulic tube nut fitting serves as the threaded connection point that seals a hydraulic line to a port or mating component within the trowel's hydraulic circuit. On hydrostatic ride-on trowels like the HTH-Series, the hydraulic system controls both blade pitch adjustment and machine drive, so a secure, leak-free fitting is critical to maintaining consistent performance and operator control. A cracked, stripped, or improperly seated fitting can result in hydraulic fluid weeping, pressure drop, or complete loss of hydraulic function — making timely replacement with the correct part essential to keeping the machine working as intended.
