Custom Ring Gaps

Selection of the proper ring gap configuration is important in sealing applications. Acceptable leakage rates, sizes of the rings and types of assembly are factors that help determine the proper gap configuration of our piston rings and seal rings. Shown here are the most common gap ring configurations. Please Contact Us to inquire about a gap configuration not shown below or give us a call 317-247-4786.


The most practical and economical ring gaps. Recommended for most applications. Good leakage control.


Widely used on rotating seals. Rings should be oriented so the leading edge points in the direction of rotation. Rings with an angle gap decrease the tendency to score at the gap.


Sometimes applied to contracting and snap rings so that they can be easily removed from the groove.


Used where two rings per groove are not practical. The step cut is used to prevent a direct flow path between the piston and cylinder. Cross section must be larger to accommodate strength to the steps.


Used for blind assembly or when ring must pass ports in the cylinder wall. Limits free expansion.


The only single rings that have tighter leakage control than any other single ring. Used on larger diameter rings when using one ring per groove.
