The Multiquip 42457 is a genuine OEM Fuel Fitting.312 Straight SAE J2044 designed for HTXG6DF, STXDF, and PRX series ride-on power trowels. As a direct OEM replacement, this fitting meets the exact specifications required for proper fuel line connection and system integrity on these machines. Sourced directly through Multiquip's authorized parts network, the 42457 ensures you are installing the correct component the first time. DHS Equipment stocks this part to help keep your concrete finishing equipment running as intended.
Key Features
- SAE J2044-Compliant Connection: — Engineered to the SAE J2044 quick-connect fuel fitting standard, ensuring a secure, leak-free seal at the fuel line interface.
- Correct .312 Straight Configuration: — The .312-inch straight geometry matches the OEM fuel line routing on these trowels, allowing direct installation without modification to the fuel system.
- Genuine OEM Component: — Manufactured to Multiquip's original material and dimensional specifications, delivering the same fit and performance as the part it replaces.
- Broad Ride-On Trowel Fitment: — Compatible with HTXG6DF hydrostatic trowels, STXDF dual-fuel super-sized trowels, and PRX hybrid power floats.
- Fuel System Integrity: — A correctly seated fuel fitting maintains steady fuel delivery to the engine; a worn or cracked fitting can cause fuel leaks, erratic engine performance, or a no-start condition on your trowel.
- Fire and Fuel Safety: — Fuel system fittings that do not meet the original SAE J2044 specification risk improper seating and fuel weepage — using the correct OEM part is essential on engine-powered finishing equipment.
The fuel fitting is a small but critical connector within the machine's fuel delivery system. It forms a sealed junction between the fuel line and the engine or fuel system component it supplies, preventing fuel from escaping under normal operating pressure. Because ride-on trowels like the HTXG6DF, STXDF, and PRX run continuously under load during concrete finishing operations, any compromise in the fuel fitting — cracking, degradation, or improper seating — can result in fuel leaks, inconsistent engine power, or a shutdown at the worst possible time on a pour.
