The TFI Racing Rubber Block Off Blank Plug 1/2" ID is a practical temporary sealing solution for situations where you need to block off a hose, line, or opening quickly and effectively. Supplied as a pack of 2, these rubber plugs are ideal for workshop use, maintenance tasks, and emergency repairs when a reliable short term stop gap is required.

Designed with a 1/2 inch internal diameter, each plug is made to fit securely and help minimise fluid loss or contamination during servicing. The flexible rubber construction allows for easy insertion and removal, making these plugs convenient to keep on hand for a wide range of automotive applications. They are especially useful when a permanent repair is not yet available and a temporary block off solution is needed to keep work moving.

These block off plugs are intended for temporary use only and should not be relied upon as a permanent fix. Whether you are working on cooling, fuel, vacuum, or other fluid related systems, they provide a simple and effective way to seal off unused or open lines during diagnostics, repairs, or component replacement.
