The Honda 17519-ZM5-003 Fitting is a genuine OEM replacement designed for GX22, GX25, GX31, GX35, and GX50 horizontal shaft engines, FG100 and FG110 tillers, HHT25 and HHT35 trimmers, and the WX10 water pump. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring a correct connection every time. Because this fitting appears across several distinct equipment classes, confirm your model and serial number against the fitment table before ordering.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this fitting meets the same connection and dimensional requirements as the original installed at the factory.
- Broad Cross-Equipment Fitment — covers GX22, GX25, GX31, GX35, and GX50 horizontal shaft engines, FG100 and FG110 tillers, HHT25 and HHT35 trimmers, and the WX10 water pump, making it a widely used service item across Honda's small-equipment lineup.
- Serial Number Verification Recommended — Honda updates parts at serial break points, so check your unit's serial number against the compatibility table to confirm part number 17519-ZM5-003 is the correct supersession for your machine.
A fitting serves as a connection point within a fluid or fuel line circuit, allowing hoses, tubes, or passages to join securely without leaking. On small engines and compact power equipment like tillers, trimmers, and lightweight pumps, a properly sealing fitting is essential to maintaining consistent fuel or fluid flow to the system it serves. A cracked, stripped, or deteriorated fitting can result in leaks, inconsistent operation, or loss of prime — replacing it with the correct OEM part restores the integrity of the circuit and keeps the equipment running as intended.
