Product Description
Choose our hydraulic oil seal for the following reasons.
1. Product Advantages
Dual-Material Synergy: Combines wear-resistant polyurethane (PU) lip seal with high-elastic nitrile rubber (NBR) X-ring, ensuring no creep at low pressure and strong extrusion resistance at high pressure (up to 31.5MPa for CPU variant).
Low-Friction & Long-Lasting: 4-lip X-ring design reduces contact stress, minimizing friction and wear; self-lubricating groove structure extends seal and system service life.
Easy Installation: Flexible sizing adapts to both hole and shaft sealing, eliminating complex fitting adjustments for quick assembly.
2. Working Principle
The MPS seal achieves sealing through pre-compression + pressure activation:
Initial seal: Radial/axial pre-compression of the X-ring creates baseline contact stress with mating surfaces.
Pressure enhancement: As system pressure rises, the X-ring deforms, increasing contact stress to block fluid leakage—ideal for dynamic (reciprocating/rotary) and static applications.

5. FAQ
Q1: Can the MPS seal replace single O-ring seals?
A1: Yes—its X-ring design offers better anti-twist performance and wider pressure adaptability than standard O-rings.
Q2: What maintenance is required?
A2: Minimal maintenance; avoid contact with sharp edges during installation and use compatible fluids (refer to Forever Seals’ fluid compatibility chart).
