What is an Extrusion Gap? An extrusion gap refers to the clearance or space between two mating surfaces in a sealing system, typically between the seal and the hardware (e.g., a piston and cylinder bore, or a rod and gland) where the seal is installed. Under pressure, the seal material may tend to flow or "extrude" into this gap, which can lead to seal damage, reduced performance, or failure over ...
