hydraulic seals - Cast Iron Piston Rings

Material: Cast Iron.
When using cast iron piston rings, it is crucial to use the correct groove design for proper performance of the cylinder. Please use the following guidelines when cutting a cast iron piston ring groove.
Groove Width: To permit the ring to slide freely into the groove, the groove must be at least 0.001 inches wider than the maximum piston ring width with a tolerance of +0.003/-0 inches.
Groove Depth: Grooves must be at least 0.015 inches deeper than the maximum radial wall thickness of the piston ring with a tolerance of +0.003/-0 inches. This is to avoid any possibility of the ring bottoming in the groove when the ring is compressed to its working diameter.
Radial Clearance: The radial clearance between the cylinder bore and piston should be less than 1/3 of the radial wall thickness of the piston ring to ensure sealing effectiveness.
