The Multiquip 12131 is a genuine OEM 90° 12MJ-16MO Fitting designed for STH series hydrostatic ride-on trowels. As a direct OEM replacement, this fitting meets the original hydraulic plumbing specifications for your machine, ensuring a correct connection without modification. Sourced directly from Multiquip, the part is the same component used in original production, making it a trusted choice for field repairs and scheduled maintenance on STH hydrostatic ride-on trowel equipment.
Key Features
- OEM Hydraulic Integrity — Manufactured to the exact thread form and angle spec of the original fitting, maintaining proper hydraulic pressure and flow characteristics throughout the circuit.
- 90° Elbow Configuration — The right-angle 12MJ-16MO profile routes hydraulic lines cleanly in tight or angled plumbing runs, connecting directly to existing ports without rerouting hoses.
- STH Series Fitment — Confirmed for STH hydrostatic ride-on trowels, so you can order with confidence knowing this is the correct part for your machine.
- Leak-Free Hydraulic Connection — A worn or damaged fitting can introduce air into the hydraulic system or cause fluid loss, leading to erratic blade pitch control or drive response; replacing with the correct OEM fitting restores system integrity.
- Genuine Multiquip Part — Backed by Multiquip's OEM standards, this fitting is built from the same materials and to the same tolerances as the original, supporting long service life under continuous hydraulic cycling.
A hydraulic fitting like the 12131 serves as a critical junction point in the machine's hydraulic plumbing, redirecting fluid flow at a 90° angle between hoses, lines, or components. The 12MJ-16MO designation identifies the specific male JIC and male O-ring face seal thread sizes on each end, which must match precisely for a leak-free, pressure-rated connection. When a fitting cracks, strips, or begins to weep fluid, the hydraulic system loses the pressure needed to accurately control blade pitch and drive function on the trowel — making prompt replacement with the correct OEM part essential to keeping the machine working as intended.
