K98 - PISTON ROD SEAL SIGNAL ACTING SEALING U RING WITH O RING
Engineered for reciprocating motion in hydraulic/pneumatic systems, this dual-seal design combines a U-ring with an O-ring for superior pressure resistance (up to 35 MPa) and low friction. Constructed from premium NBR/FKM rubber, it withstands oils, greases, and extreme temperatures (-40°C to 120°C) in heavy machinery, agricultural equipment, and industrial cylinders.
The U-ring profile provides dynamic sealing against high pressures, while the O-ring ensures static stability and compensates for axial misalignment. IP67-rated to prevent dust/water ingress, it reduces wear and extends service life by 40% compared to standard seals. Quick installation with no special tools required, ideal for field repairs.
