The Genie 189785GT is a genuine OEM Buna-N Rubber Washer designed for Genie AL-series portable light towers, including the AL4000, AL5000, AL4, AL5, and AL5HT. Sourced directly from Genie, this washer meets the same material and dimensional standards as the original component installed at the factory. Cross-reference part number 189785GT against your parts manual to confirm the correct application before ordering. Whether you're performing routine maintenance or addressing a seal failure, this is the correct OEM replacement for your AL-series light tower.
Key Features
- Buna-N Material Grade — Buna-N (nitrile) rubber provides strong resistance to petroleum-based fluids, oils, and weathering — essential for sealing applications in light tower power and fuel systems.
- Direct OEM Replacement — Matches the original washer's profile and compression characteristics, seating correctly without modification or adaptation to existing fasteners and fittings.
- Broad AL-Series Fitment — Fits Genie AL4, AL4000, AL5, AL5000, and AL5HT portable light towers, covering a wide range of jobsite lighting equipment in one part number.
- Seal Integrity Under Load — A properly functioning rubber washer maintains a fluid-tight seal at connections and fittings; a degraded or cracked washer can allow leaks that compromise light tower operation and create a hazardous work environment.
- Genuine OEM Confidence — As a genuine Genie part, this washer is manufactured to the same specification as the original, ensuring correct durometer, size, and chemical compatibility for the AL-series platform.
A rubber washer serves as a compressible sealing element between mating surfaces — typically at fluid fittings, fastener connections, or access covers — preventing leaks and protecting surrounding components from moisture and fluid ingress. Buna-N nitrile rubber is specifically chosen for environments where contact with fuel, oil, or hydraulic fluid is likely, as it resists swelling and degradation that would compromise the seal. When this washer hardens, cracks, or deforms with age, the seal fails, which can lead to fluid leaks, contamination, or damage to adjacent components on the light tower.
