NBR O-ring Packing, 1.5 mm Thickness | Sealing Tech-G

The Sealing Tech-G NBR (Nitrile Butadiene Rubber) O-ring with a 1.5 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 where hydrocarbons are present. Its advanced formulation ensures excellent abrasion and tear resistance, extending the seal's lifespan and minimizing maintenance costs. With 58 available internal diameters — from 1.5 mm to 90 mm — it is the most versatile option in the NBR 1.5 mm line, covering a wide range of industrial applications.

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 machinery: inspection gaskets, covers, and connections with oil or water
• Industrial refrigeration: seals in systems with NBR-compatible refrigerants
