Key Features
- Exact Dimensional Fit — The .38 diameter and domed profile match the original specification, seating flush and secure without trimming or adapting.
- Broad Genie Fitment — Compatible with multiple Genie equipment families including S and SX telescopic booms, Z and ZX articulating booms, GS scissor lifts, TZ trailer-mounted booms, and AWP personnel lifts.
- Port and Opening Protection — A correctly fitted plug seals ports, fastener holes, and openings against moisture, debris, and contamination that can lead to corrosion or damage over time.
- Simple Serviceability — The domed nylon design installs and removes quickly, making it a practical choice for routine maintenance and field repairs across a broad machine range.
A nylon plug is used to seal open ports, holes, or recesses on a machine's frame, panels, or components, blocking out moisture, dust, and debris that can accelerate wear or cause damage to surrounding parts. The domed profile helps it seat cleanly in the opening it covers, maintaining a secure fit through normal vibration and use. A missing or damaged plug leaves the opening exposed, which can allow contamination to build up in areas where it is difficult to clean and may eventually affect nearby components.
