Expansion Plugs

Stop coolant or oil leaks fast by sealing worn or drilled engine and exhaust passages with expansion plugs. We stock zinc plated steel concave, cup and shallow cup styles for a universal fit. Use concave plugs when you need a tight bite in thinner walls, go cup for deeper bores and shallow cup where clearance is tight.
