The Multiquip 42446 Fuel Cap is a genuine OEM Fuel Cap designed for HTXG6DF, STXDF, and MD105 ride-on power trowels, as well as the LS300G concrete pump. As a direct Multiquip OEM component, this Fuel Cap is built to the same specification as the original part installed at the factory, ensuring a correct, secure seal on the fuel tank. Sourced directly through authorized Multiquip channels, part number 42446 is the right choice when you need a verified fit without guesswork.
Key Features
- OEM-Grade Sealing Integrity — Manufactured to Multiquip's original material and thread specification, maintaining a pressure-safe, vapor-tight closure on the fuel tank.
- Thread-Matched Direct Replacement — Threads directly onto the factory fuel tank neck with no modification to the tank or filler neck required.
- Broad Fitment Across Multiquip Lines — Compatible with HTXG6DF and STXDF hydrostatic ride-on trowels, MD105 mid-size ride-on trowel, and LS300G concrete pump.
- Fuel System Protection — A properly sealing fuel cap prevents fuel evaporation, contamination from debris, and pressure imbalances that can disrupt fuel delivery and cause hard-starting or stalling.
- Fuel Safety Compliance — A secure, OEM-specified cap is a critical safety component — a cracked, missing, or poorly fitting cap can create a fire hazard in the presence of heat or sparks on an active jobsite.
The fuel cap seals the opening of the machine's fuel tank, keeping fuel contained and the system protected from outside contaminants such as dust, water, and debris. A correctly functioning cap also allows the tank to breathe properly, preventing vacuum lock that can restrict fuel flow to the engine. When the cap fails — through cracking, stripped threads, or a degraded gasket — fuel leaks, evaporation, and contamination become immediate concerns that can shorten engine life and create unsafe operating conditions.
