The Multiquip 11721 Straight Fitting 6MJ-6MO is a genuine OEM hydraulic fitting designed for Whiteman ride-on power trowels and ride-on roller screeds across the STX55, HTX44, HHXD5, HHXG5, WRS5200, and WRSPUDF model families. As a direct Multiquip OEM component, part 11721 is manufactured to the exact thread specification and dimensional standard required by these machines, ensuring a secure, leak-free connection in the hydraulic circuit. Confirm your model code against the fitment list before ordering to ensure this is the correct fitting for your configuration.
Key Features
- Genuine OEM Thread Specification — Machined to the exact 6MJ-6MO male JIC to male ORB thread pairing required by the original hydraulic plumbing layout, eliminating the guesswork of aftermarket sizing.
- Straight Configuration for Direct Line Routing — The inline straight body allows for clean, low-profile hydraulic line connections where space and routing angle demand a non-angled fitting.
- Broad Model Coverage — Fits STX55Y6, STX55J6, STXD6i, HTX44Y4, HTX44Y5, HTX44K4, HTX44K5, HTXD6i, HHXD5, HHXD5-ES, HHXG5, WRS5200, WRS5200DFPU, and WRSPUDF equipment.
- Hydraulic Integrity Under Operating Pressure — A correctly installed fitting maintains consistent hydraulic pressure to the blade pitch and drive systems; a leaking or failed fitting causes pressure loss, sluggish blade response, and potential system damage.
- Fuel and Fluid System Safety — Proper OEM fitting specification is critical in hydraulic circuits — an incorrectly rated or improperly seated fitting can result in hydraulic fluid loss, fire risk, or uncontrolled machine movement.
A straight hydraulic fitting connects two hydraulic lines or components in a single inline path, maintaining sealed fluid flow within the machine's hydraulic circuit. On ride-on trowels and roller screeds, the hydraulic system controls both blade pitch adjustment and machine propulsion, meaning any fitting that leaks or fails under pressure directly impairs operator control and machine output. Replacing a damaged or worn fitting like the Multiquip 11721 promptly prevents pressure drop, fluid contamination, and progressive damage to pumps, valves, and cylinders downstream.
