This is the same heavy-duty cap supplied with our 5 Gallon Square Utility Jugs, Part No. 2558. This durable, thick-wall cap will also work on most other brand jugs that use a 3.5" diameter thread. Includes gasket and pipe plug.
Add our 18 Inch Filler Hose (Part No. 2565, sold separately) to pour from your jug without a funnel.
