Multiquip 21407 Fitting Str 20Mo-20Mo Adj

The Multiquip 21407 Fitting Str 20Mo-20Mo Adj is a genuine OEM hydraulic fitting designed for Whiteman ride-on power trowel models including the HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HTXD6i, STX55J6, STX55Y6, and STXD6i. As a direct OEM replacement, 21407 is manufactured to the same specifications as the original component, ensuring a correct, trouble-free installation in the hydraulic circuit. Sourced directly through authorized Multiquip distribution channels, this fitting is the right choice when you need verified part accuracy for your ride-on trowel.

Key Features

• Genuine OEM Construction — Machined to original equipment tolerances for consistent thread engagement and leak-free hydraulic connections under operating pressure.
• Straight Male-to-Male Adjustable Configuration — The 20Mo-20Mo adjustable design allows correct alignment of hydraulic lines during installation, eliminating the need to twist or stress adjacent hoses.
• Broad HTX and STX Series Fitment — Confirmed for HTX44 and STX55 series ride-on trowels, covering K4, K5, Y4, Y5, and i-suffix hydrostatic models.
• Hydraulic System Integrity — A correctly seated fitting maintains proper hydraulic pressure delivery to the blade pitch and drive circuits; a failed or cross-threaded fitting can result in pressure loss and loss of trowel control.
• Verified Part Number — Order with confidence using Multiquip part number 21407 to confirm you are receiving the exact component specified for your machine.

This fitting is a straight male-to-male adjustable hydraulic connector used within the hydraulic circuit of Whiteman hydrostatic ride-on power trowels. It routes and seals pressurized hydraulic fluid between components such as the drive and blade-pitch control circuits, allowing the operator to adjust blade angle and propel the machine. When a fitting of this type leaks, corrodes, or sustains thread damage, hydraulic pressure drops, which directly compromises blade pitch response and drive performance — making prompt replacement essential to safe and productive finishing operations.
