HSN/HNBR O'Rings

About HSN/HNBR O'Rings

Rubber O Rings are precisely designed sealing components that are notable for their torus shape. These are installed in groove section of single or multiple parts by applying compression force for attaining hermetic fastening result. In brief, these are the elastomer loops that are noteworthy for their cross and circular sectional design. The offered sealing rings are suitable both for passive and active works utilization purpose. Being cost effective, these are considered as the most ergonomic sealing components available in the market. Simple manufacturing technique, trouble free usage and easy fitting method are some key attributes of these sealing parts. Based on their hardness level and materials of construction, these o rings are used as essential sealing materials for equipments like filters, generators, lubricating systems, compressors, LPG regulators, gas-springs, valves and pumps, pneumatic and hydraulic cylinders, automobiles and actuators to name a few. We have grown expertise in the manufacturing arena of Rubber O Rings that are made of standard grade rubbers like EPDM, neoprene, silicon, natural, viton, nitrile and others. Customers can obtain these o rings in different metric size options, in non standard and standard dimension range from the huge collection of MREW. Clients can also attain these o rings in required size or fluid resistance configurations from this organization. Apart from providing standard o rings, MREW is also instrumental in offering these with latest sealing design options like Quad Rings that are used for low pressure sealing purpose

Superior Resistance for Demanding Applications

HSN/HNBR O-Rings deliver remarkable performance, especially in environments exposed to aggressive oils, fuels, ozone, and high temperatures. Their robust chemical structure ensures they retain sealing integrity even when subjected to low gas permeability challenges, hydraulic fluids, and industrial lubricants. This makes them a preferred choice for automotive, oil and gas, and heavy machinery industries looking for long service life and minimal maintenance requirement.


Precision Manufacturing and Customization

Produced through compression and injection molding, HSN/HNBR O-Rings are available in a wide range of sizes, thicknesses, and durometers (7090 Shore A). The smooth, defect-free finish and tight tolerances (0.05 mm) ensure a reliable fit and function in both standard and non-standard applications. Customization options are extensive, including color, diameter (1 mm 500 mm), and thickness (1 mm 10 mm), tailored specifically to user requirements.


Versatile Usage Across Multiple Industries

Owing to their exceptional oil and chemical resistance, along with extended operational lifespan, these O-rings are extensively used for sealing parts in hydraulic systems, automotive assemblies, fuel circuits, air conditioning units, and heavy industrial equipment. Their adaptability makes them a valuable component in sectors where reliable sealing and resistance to harsh media is essential for safe and efficient operations.
