Key Technical Advantages
The NBR FKM rubber quad-ring utilizes a sophisticated four-lobed design that provides two sealing surfaces per side, doubling the security compared to traditional O-rings. This unique geometry allows for a lower radial squeeze, which minimizes friction and extends the service life of dynamic components. Because the cross-section is square-shaped, the seal resists the tendency to roll in the groove, effectively preventing spiral failure during long-stroke reciprocating motion. The recessed valleys between the lips also serve as lubricant reservoirs, ensuring smooth operation even in systems with intermittent lubrication.
Industrial Applications & Compatibility
These high-performance seals are essential in heavy-duty hydraulic applications, where they prevent fluid bypass in pistons and rods subject to high-frequency oscillations.
They are extensively integrated into chemical processing valves and fuel systems, offering superior resistance to petroleum-based oils, fuels, and aggressive solvents.
In pneumatic automation, the low friction characteristic of the quad-ring enables faster cycle times and reduces the energy required for actuator movement.
The dual-material options allow these rings to be deployed in both standard temperature industrial machinery and high-heat aerospace or automotive engine environments.
