About O RING

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

Versatile Chemical Resistance

Engineered using high-quality rubber compounds like Nitrile (NBR), EPDM, and Viton, our O Rings exhibit reliable chemical resistance tailored for applications involving oils, solvents, and water. Their robust design ensures lasting performance across a range of challenging environments where contaminants and fluids are present.

Custom Sizing & Flexible Design

Available in standard and custom dimensions with widths from 2 mm to 12 mm and diameters from 3 mm up to 300 mm, these O Rings accommodate varying mechanical setups. With options for specific hardness (60-80 Shore A) and cross-sectional thickness (1-15 mm), every sealing solution is precisely matched to your system requirements.

Exceptional Mechanical Properties

These O Rings deliver high elongation at break (200%400%), a tensile strength of 1220 MPa, and a low compression set. Their resilience makes them ideal for heavy-duty and sensitive applications, supporting reliable operation in both static and dynamic sealing environments. All rings feature consistent tolerances (0.05 mm) and smooth surface finish.

FAQs of O RING:

Q: How do O Rings with chemical resistance maintain their durability in harsh environments?

A: The rubber types used, such as Nitrile (NBR), Viton, and EPDM, are specifically formulated for excellent resistance to chemicals, oils, water, and temperature fluctuations. This ensures O Rings retain their sealing integrity and flexibility, even when exposed to aggressive fluids or outdoor elements.

Q: What applications are these O Rings most suitable for?

A: These O Rings are designed for use in sealing, gasketing, hydraulic and pneumatic systems, automotive assemblies, plumbing, machinery, and other fluid sealing applications. Their customizable sizes and strong material properties accommodate both static and dynamic operations in various industries.

Q: When should I select a specific rubber type for my application?

A: Rubber selection should be based on the operating environment and the substances the O Ring may encounter. Use Nitrile (NBR) for oil resistance, EPDM for ozone and water exposure, and Viton for high temperature and aggressive chemicals. Each materials properties align with different industrial requirements.

Q: Where can these O Rings be used regarding operating environments?

A: They are suitable for both indoor and outdoor environments thanks to their strong ozone, weather, and UV resistance (especially EPDM and Viton). Their low water absorption and design versatility make them ideal for a wide range of installation contexts from industrial plants to automotive workshops.

Q: What are the main steps involved in the O Ring manufacturing process?

A: These O Rings are produced through single piece moulding, ensuring uniformity and accuracy. Precision tooling allows for tight tolerances and a smooth surface finish. Customization in size, shape, and hardness ensures each batch meets the specific application and quality demands required by industries.

Q: How does using these O Rings benefit fluid sealing systems?

A: The high flexibility, oil and chemical resistance, and excellent compression set resistance of these O Rings lead to long-term, leak-free performance. Their adaptability to pressure (up to 3000 psi) and temperature variations greatly minimizes downtime and maintenance in sealing applications.
