This rubber block is a GSK tested high-performance component crafted from premium HNBR (Hydrogenated Nitrile Butadiene Rubber), engineered for precision positioning and vibration damping in harsh operating environments. Its custom molded rectangular design—featuring double grooves, a central slotted hole, and stepped edges—ensures a perfect fit for specific automotive and industrial assemblies, while the HNBR material delivers exceptional resistance to temperatures from -40°C to 150°C, mineral oils, hydraulic fluids, and ozone aging. Rigorously validated under GSK standards, it maintains structural integrity and sealing performance under dynamic pressure and vibration, balancing elasticity for shock absorption with structural rigidity for precise positioning. This component is ideal for automotive engine mounts, hydraulic valve assemblies, and industrial machinery where reliable vibration control, oil resistance, and dimensional accuracy are critical.

Part Number
281518773
Material
HNBR (Hydrogenated Nitrile Butadiene Rubber), black
GSK Tested Reliability: Verified through strict GSK testing protocols to ensure consistent dimensional accuracy, performance stability, and durability in critical applications.
Superior HNBR Material Performance: Outperforms standard NBR with enhanced oil resistance, anti-aging properties, and temperature tolerance (-40°C to 150°C), extending service life by 2–3 times.
Custom Precision Design: Molded with double grooves, slotted hole, and stepped edges for exact assembly alignment, eliminating fitment gaps and improving structural stability.
Dual-Function Performance: Combines vibration isolation/shock absorption with precision positioning, reducing mechanical wear and operational noise in dynamic systems.
Harsh Environment Adaptability: Resists compression set, tearing, and chemical corrosion, suitable for automotive engine bays and industrial hydraulic environments.
Applications:
Positions and dampens vibration in automotive engine components, reducing engine vibration transmission to the chassis and improving ride comfort.
Absorbs shock in hydraulic equipment valve blocks, minimizing wear on metal mating parts and maintaining system pressure stability.
Provides precision alignment and cushioning in industrial machinery assemblies, ensuring smooth operation and reducing operational noise.
Seals the interface between mechanical components in oil-contact environments, preventing fluid leakage and protecting against contamination.
Resists aging and fatigue in long-term dynamic operation, extending the service life of automotive and industrial equipment.
