Core Plugs

We stock a large range of core plugs in both metric and imperial sizes of cup and dish plug designs. Cup plugs have a side wall whereas dish plugs have no side wall but are more concave to aid sealing. Core plugs are manufactured from CR4 zinc plated mild steel and are used to fill the casting holes in engines, as well as for various other applications.
