O-ring Packing in NBR, 2mm Thickness | Sealing Tech-G

The Sealing Tech-G NBR (Nitrile Butadiene Rubber) O-ring with a 2 mm thickness is a robust and reliable sealing solution for various industrial applications. Highly compatible with oils, fuels, lubricants, water, and numerous non-polar solvents, it is the elastomer of choice for environments with hydrocarbons. Its advanced formulation ensures excellent abrasion and tear resistance, extending seal life and minimizing maintenance costs. With 84 available internal diameters—from 3 mm to 140 mm—it is the most versatile option in the NBR 2 mm line, covering everything from precision applications to large-format industrial equipment.

Applications

• Hydraulic and pneumatic systems: cylinders, valves, and actuators
• Automotive: engine, transmission, and fuel system seals
• Pumps and compressors: static and dynamic seals in contact with oils
• Industrial valves: seat and stem seals in oily fluids
• Oil and gas industry: seals in equipment exposed to hydrocarbons
• General and heavy machinery: inspection gaskets, covers, and flanges
• Industrial refrigeration and process equipment: seals in systems with NBR-compatible fluids
