The Multiquip 42563 Oil Drain Valve 18MM is a genuine OEM component designed for STX6H and PRX series ride-on power trowels. As a direct OEM replacement, this valve is manufactured to the same specification as the original, ensuring a correct 18MM fit without modification to the drain port. Compatible models include the STX6H hydrostatic ride-on trowel and PRX hybrid power float series. Sourced directly through Multiquip's authorized parts network, the 42563 is the exact part your machine was built with.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specification, ensuring correct thread pitch, valve body dimensions, and material grade for the 18MM drain port on ride-on trowel engines.
- Direct Port Fit — Threads directly into the existing 18MM oil drain port with no rework or adapter required, seating flush for a clean, leak-free seal.
- Confirmed Trowel Fitment — Verified for STX6H hydrostatic ride-on trowels and PRX hybrid power floats — cross-check your model code before ordering.
- Leak-Free Oil Retention — A properly functioning drain valve keeps engine oil sealed during operation; a worn or damaged valve risks slow oil loss, contamination, and accelerated engine wear on high-cycle trowel machines.
- Service Interval Ready — Designed for straightforward removal and reinstallation during scheduled oil changes, supporting consistent engine maintenance on your trowel fleet.
The oil drain valve controls the opening and closing of the engine's oil drain port, allowing oil to be fully evacuated during service intervals and securely sealed during operation. On ride-on trowels like the STX6H and PRX, which run demanding finishing schedules, a compromised drain valve can result in slow seepage that goes unnoticed until oil levels drop dangerously low. Replacing a worn or leaking valve with the correct OEM part — the Multiquip 42563 — keeps the drain circuit sealed and ensures clean, complete oil changes every service cycle.
