Barrel Plugs
Flanged barrel plugs, also known as plastic bungs, barrel bung plugs, or barrel bung caps, are essential sealing components designed to provide secure closure for holes in barrels, containers, and industrial equipment. These versatile plastic bungs for holes are manufactured from premium LDPE (Low-Density Polyethylene), offering exceptional durability and chemical resistance properties. Flanged barrel plugs serve as protective barriers that seal, plug, and secure barrel openings whilst preventing contamination, spillage, and unwanted ingress during storage, transportation, and processing operations.
Throughout UK industries including chemical processing, pharmaceutical manufacturing, food and beverage production, automotive, and general manufacturing, flanged barrel plugs deliver reliable sealing performance. Their primary benefit lies in providing an effective seal that maintains product integrity whilst offering easy installation and removal capabilities. The distinctive flanged head design eliminates the need for additional tools during fitting, making these barrel bung plugs ideal for applications requiring frequent access. Available in comprehensive size ranges from 2mm to 112mm diameter, these plastic barrel plugs accommodate diverse industrial requirements whilst maintaining consistent sealing performance across various applications.

Frequently Asked Questions
Plastic barrel plugs are widely used across engineering, automotive, manufacturing, fabrication and general industrial applications to protect openings during production, handling and storage.
Yes. As a push-fit component, a barrel plug can generally be removed when access to the opening is required. Suitability for reuse depends on the condition of the plug after removal.
Flanged Barrel Plugs are designed to close and protect holes, bores and openings in components. They provide a simple push-fit solution for manufacturing, storage, transportation and general component protection.
The flange sits against the surrounding surface to help prevent over-insertion while providing additional coverage around the opening. It also creates a neat finished appearance once installed.
The barrel-shaped body fits inside a compatible opening and grips the internal surface. This provides secure retention without requiring adhesives, screws or additional fixings.
Our Flanged Barrel Plugs cover a broad range of sizes from approximately 2mm to 112mm, providing options for small component holes through to much larger openings.
Measure the internal diameter of the hole or bore you need to plug then compare it with the recommended fitting dimensions. You should also check the flange diameter where surrounding clearance is limited.
