	Metric Cast Iron Piston Rings When using cast iron piston rings, it is crucial to use the correct groove design for proper performance of the cylinder. Groove width: To permit the ring to slide freely into the groove, the groove must be at least .025mm wider than the maximum piston ring width with a tolerance of +.076mm / -0.000mm Groove Depth: Grooves must be at least .381mm" deeper than the maximum radial wall thickness of the piston ring with a tolerance of +.0762mm / -0.000mm 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 the piston should be less than 1/3 of the radial wall thickness of the piston ring to ensure sealing effectiveness. Material: Iron Note: Some minimums may apply. If you can’t find something you’re looking for, give us a call at 800-445-7803.

	Metric O-Rings An O-Ring is a torus, or doughnut shaped seal used for closing off a passageway to prevent escape of a gas or fluid from a cylinder or other container. O-Rings are generally made from an elastomer, but are available in many other materials. Note: Some minimums may apply. If you can’t find something you’re looking for, give us a call at 800-445-7803.

	Metric Oil Seals Style MOS A shaft seal is a barrier with four functions. It retains lubricants or liquids, excludes contaminants, separates fluids and confines pressure. Essentially, they consist of a rubber sealing lip, a stiffening metal core, and a garter spring. Depending on the application. There are three standard Lip types: A, B,and C. See exploded image of ADL style below. Type A The rubber elastomer outer covering tolerates thermal expansion as well as roughness in the housing bore. There will be no fretting corrosion. Damage to the housing bore will be prevented when frequently replacing the seal. This type qualifies for sealing gaseous or liquid media. Type B Metallic casing enables easier fitting. However, this type demands closer tolerances in the housing bore to ensure the sealing process. Type C Metallic casing with reinforcing cap. Sealing and mounting are identical with type B. This type is applied in case of rougher operating conditions and where larger dimensions are utilized. Less delicate in case of incorrect mounting due to reinforcing cap. Material: Rubber Seal, Steel Case Temperature Range: - 40 To + 225 F Pressure Range: 10 PSI @ 1000 FPM NBR=Nitrile FPM= Viton Call for technical assistance.

	Metric Speedi Sleeves The quickest and sensible way to repair worn shafts. To seal efficently, radial shaft seals must run against a smooth surface-the seal counterface. If the counterface becomes worn as it usually does, then the seal will no longer be able to fullfill its function, which is to retain lubricant and exclude contaminants-solid particles as well as liquid. Normally, the counterface will become grooved as a contaminant particle is caught under the seal lip and abades a track as the shaft rotates. As this continues, the seal will allow more particles to pass or get stuck, and seal efficency deteriorates, eventually leading to malfunction of the component the seal is ment to protect. * Indicates Speedie-Sleeve Gold product Note: Some minimums may apply.
