The Multiquip 21130 Straight Fitting 16Mo-16Mo Adjustable is a genuine OEM hydraulic fitting designed for HTX44 series ride-on power trowels and WRS5200 series ride-on roller screeds. As a direct factory replacement, this fitting ensures a secure, leak-free connection within the hydraulic circuit — maintaining the fluid integrity these machines depend on. Confirmed fitment includes the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, WRS5200, WRS5200DFPU, and WRSPUDF models.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to Multiquip's exact port geometry and thread specification, ensuring the straight adjustable fitting seats and seals correctly under operating hydraulic pressure.
- 16Mo-16Mo Adjustable Configuration — Both ports share the same 16 Male O-ring (16Mo) thread size with an adjustable orientation, allowing precise directional alignment during installation without compromising the seal.
- Broad Series Fitment — Compatible with HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, WRS5200, WRS5200DFPU, and WRSPUDF models, covering multiple engine and configuration variants across two Multiquip equipment families.
- Hydraulic Circuit Performance — A correctly seated fitting maintains stable hydraulic pressure throughout the system, supporting consistent blade pitch control on trowels and smooth drive operation on roller screeds.
- Drop-In Replacement — Matches the original fitting's thread form, body dimensions, and adjustable locknut design so it installs directly into the existing hydraulic line without reworking surrounding hardware.
A straight adjustable hydraulic fitting connects two hydraulic lines or components in a linear path while allowing the fitting body to be rotated and locked at the correct angle during assembly. In machines like ride-on trowels and roller screeds, these fittings are critical junction points in the hydraulic system that controls blade pitch, steering, and drive functions. A fitting that is worn, cross-threaded, or cracked can cause slow hydraulic leaks or sudden pressure loss — leading to erratic blade response or loss of drive control on the machine.
