NBR N90 O-Rings in Dubai, UAE — High-Hardness Nitrile Seals
Al Omran Rubber Trading stocks 395 NBR N90 O-ring size variants in Dubai — the hardest Nitrile grade for high-pressure hydraulic and pneumatic sealing across the UAE, GCC, and Africa.
What Are NBR N90 O-Rings?
NBR Shore 90 O-rings are the high-hardness variant of standard Nitrile rubber. The increased hardness provides superior extrusion resistance under high system pressures, making them essential for hydraulic cylinders operating above 100 bar, pneumatic systems with small clearances, and applications where standard Shore 70 O-rings tend to blow out.
Applications in UAE & GCC
NBR N90 O-rings are used in high-pressure hydraulic systems across UAE oil & gas facilities, heavy construction equipment throughout the Emirates, industrial machinery in Sharjah and Dubai Industrial Parks, and marine hydraulic deck equipment in Fujairah and Jebel Ali ports.
