The MYA dual-use seal is a game-changer for pneumatic system design and maintenance. Engineered with a symmetrical U-cup profile, this single component serves both as a piston seal (outer diameter sealing) and a rod seal (inner diameter sealing) — eliminating the need for separate inventory items and simplifying spare parts management.
What makes the MYA seal truly innovative is its Y-shaped cross-section with two sealing lips and an internal energizing rib. This geometry creates a self-energizing effect: as system pressure rises, the sealing lips are forced outward against the cylinder bore (piston mode) or inward against the rod surface (rod mode), ensuring a tighter seal exactly when needed. The result is reliable bidirectional sealing across a wide pressure range up to 1.6 MPa.
Technical Highlights:
Pressure: Up to 16 bar
Speed: 1 m/s maximum
Temperature Range: -25°C to +100°C (standard NBR) / up to 150°C (FKM option)
Available Materials: NBR, S-Kid (special nitrile), FKM
Compatibility: Fits JIS B2401-P series O-ring groove dimensions
The MYA seal‘s compact axial length allows installation in tight spaces without sacrificing sealing performance. It performs consistently in both lubricated and oil-free air environments — critical for modern pneumatic systems where oil-free operation is increasingly mandated.
Key Applications: Pneumatic cylinders, directional control valves, air compressors, industrial robots, and automation equipment requiring dependable reciprocating motion sealing.
By choosing the MYA dual-use seal, you reduce inventory complexity, lower maintenance costs, and gain a proven sealing solution trusted in industrial pneumatic applications worldwide. It is the smart, space-saving alternative to single-function seals.
