The Multiquip 17620Z4H010 Tank Cap is a genuine OEM replacement designed for CA4HM walk-behind power trowels, WM120SH and WM120PH Whiteman mixers, and EM120S and EM120P Series Essick mixers. Sourced directly from Multiquip, this cap meets the original equipment specification for GX120UT1QX2-powered machines. Choosing the correct OEM tank cap ensures a proper seal and keeps your equipment operating as intended across all compatible models.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the exact venting and sealing specification of the GX120UT1QX2 engine, ensuring consistent fuel system pressure management.
- Direct Drop-In Replacement — Threads directly onto the original fuel tank filler neck with no fitting adjustments, matching the OEM thread pitch and cap diameter.
- Broad Model Coverage — Compatible with CA4HM, WM120SH, WM120PH, EM120S Series, and EM120P Series equipment, covering both trowel and mixer applications.
- Fuel System Protection — A properly sealed tank cap prevents fuel contamination, evaporation loss, and pressure imbalance that can cause hard starting or erratic engine performance.
- Fuel Safety Compliance — A correctly sealing cap is essential for safe fuel containment, helping prevent spills and vapor release during operation and transport.
The tank cap seals the fuel filler opening on the engine's fuel tank, maintaining proper pressure balance between the tank interior and the atmosphere. A built-in vent allows air to enter as fuel is consumed, preventing a vacuum lock that would starve the engine of fuel. When the cap fails — through a cracked body, damaged threads, or a deteriorated seal — it can allow fuel to leak, permit dirt and moisture to enter the tank, or disrupt the fuel flow needed for consistent engine operation.
