Custom NBR Extruded Rubber Strip for Oil-Resistant Sealing
Product Characteristics
Material: Nitrile rubber blend, built to withstand contact with mineral oils and grease
Production: Continuous extrusion process, profile dimensions kept consistent along length
Primary use: Seal gaps against oil seepage, block dust and debris entry
Fluid tolerance: Low swelling rate when in prolonged contact with lubricants
Wear trait: Holds up to light to moderate surface friction from moving components
Elastic behavior: Bounces back after repeated compression without permanent set
Surface state: Clean finish with minimal burrs for straightforward mounting
Custom options: Alter cross-section shape, hardness, and cut-to-length sizes
Usage scenarios: Gearboxes, pump housings, hydraulic units and automotive assemblies
Production run: Physical properties remain steady through large batch orders
Product Description
Made from nitrile rubber blends, this extruded strip is developed for sealing points that face recurring contact with oils and lubricants. When exposed to mineral oils, gear grease, and standard hydraulic fluids, the material resists excessive swelling and softening that can break a seal over time.
The continuous extrusion method forms a uniform profile along the whole length. It retains enough elasticity under repeated compression, maintaining a tight fit at joint gaps to stop oil leaks and keep dust out of equipment interiors. It also handles surface friction better than many general-purpose rubber grades during moving-part contact.
Performance stays reliable across typical operating temperature ranges. Cross-section shapes, hardness, and cut lengths are adjustable according to supplied samples or engineering drawings. It fits sealing needs on pump casings, gearboxes, and other mechanical assemblies where oil contact cannot be avoided.
