This two piece piston seal design comes made with a heat-stabilized, thermoplastic step-cut ring along with a profiled NBR energizer. This product offers extreme strength and resistance to extrusion, a very high resistance to abrasion, and ease of installation thanks to the step cut design and chamfered edges. The design also allows the seal to pass over ports without damage and offers greater resistance to surface roughness in comparison to any elastomer seals. The profiled energizer offers improved dynamic sealing ability, responding quickly to pressure changes and providing excellent sealing characteristics under a wide range of pressure conditions.
Glass Filled Nylon Material | 2.408 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible. Piston diameter “I” dimensions are given for pistons without wear rings.

END CLEARANCE End clearance on piston rings depends on ring design, material andapplication. The following end clearances are provided as a standard for hydraulic cylinder applications. When using 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 an iron piston ring groove. GROOVE WIDTH: To permit the ring to slide freely into the groove, the groove must be at least 0.001” wider than the maximum piston ring width with a tolerance of +0.003”/-0.000”. GROOVE DEPTH: Grooves must be at least 0.015” deeper than the maximum radial wall thickness of the piston ring with a tolerance of +0.003”/-0.000”. 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.
