1/4" BSP PORT PLUG STEEL ZINC COATED

The BSP (British Standard Pipe) plugs have tapered threads and sealing is done by the threads themselves. Always use a small amount of AeroSeal (AF98-2023) on all BSP threads and tighten until the it stops. These BSP plugs are ideal for sealing up ports and fittings that are unused such as unused holes in your intake manifold, or any open vacuum, coolant, or oil holes. Each plug features an internal hex which provides an easy installation and a better appearance. These plugs feature a steel construction with a zinc coated or black coated finish.
