Truck-Lite 97933 – Round Sealing Black Rubber O-Ring for Model 50 Junction Boxes
Safeguard your commercial vehicle’s primary electrical distribution hub from the elements with the genuine Truck-Lite 97933 Round Sealing Black Rubber O-Ring. Specifically engineered for Truck-Lite Model 50 terminal junction boxes, this premium elastomeric O-ring forms a critical, weather-tight barrier between the junction box cap and body.
Electrical failures on trailers are frequently caused by moisture, road salt, and dirt creeping into junction blocks. By replacing a stretched, cracked, or dry-rotted seal with the Truck-Lite 97933 during routine preventive maintenance, you actively prevent terminal corrosion, short circuits, and unexpected roadside compliance issues.
The Truck-Lite 97933 rubber O-ring is a direct factory match for the following Truck-Lite distribution units:
-
Model 50 8-Terminal Junction Box: 50800
-
Model 50 12-Terminal Junction Box: 50801
