About HSN/HNBR Gaskets

Gasket is known as a fixed mechanical sealing component which is installed in the gap between two contact parts to avoid discharge or leakage under specific compressive force. The selection and utilization of rubber materials for the production of this sealing part depends on the type of work and working environment. Some of these rubber materials can endure maximum cold and maximum heat. The properties of some of the rubber items remain unchanged even when these come in contact with corrosive chemicals.
Good elasticity level, high cold and heat withstanding capacity, weather proof design and non absorbent quality are some key attributes of the premium quality rubber sealing part offered by MREW. Our team of professionals with in depth domain knowledge provides necessary guidance for selection of suitable rubber sealing part as per different application type.
We are reckoned for our expertise in manufacturing of rubber Gaskets from all sorts of rubber materials that include natural, silicon, EPDM, neoprene, viton, nitrile and others.

Superior Chemical & Ozone Resistance

HSN/HNBR gaskets withstand harsh conditions due to their exceptional resistance to acids, alkalis, oils, and solvents. Tested for ozone exposure, they show no cracking after 72 hours at 50 pphm and 40C, making them reliable for demanding industrial environments.

Versatile Customization Options

Choose from standard colours or request unique hues for easy identification. Available in ring, round, or custom shapes and finishes, these gaskets can be tailored for specific thicknesses, hardness levels, and applications, including automotive and chemical processing uses.

Advanced Molding Technologies

Compression and injection molding techniques ensure precise dimensions and consistent quality across every gasket produced. Optional stainless steel or carbon steel rings provide added durability for critical sealing applications in high-pressure or corrosive systems.

FAQs of HSN/HNBR Gaskets:

Q: How do HSN/HNBR gaskets perform under high pressure and temperature conditions?

A: HSN/HNBR gaskets are designed to withstand pressures up to 150 bar and continuous temperatures of 160C, with short peaks up to 180C. Their robustness ensures reliable sealing in demanding industrial systems.

Q: What is the chemical compatibility of these gaskets for industrial use?

A: HSN/HNBR gaskets are highly resistant to acids, alkalis, solvents, oils, water, and coolants. This makes them suitable for chemical processing, oil & gas, and other media handling applications requiring reliable sealing and prolonged service life.

Q: When should I consider custom colours or shapes for my gasket requirements?

A: Custom colours and shapes are recommended when you need easy identification, unique design specifications, or solutions for non-standard sealing surfaces. These options enhance operational efficiency and flexibility across diverse industries.

Q: Where are these gaskets commonly used, and for what applications?

A: These gaskets are widely utilized in automotive systems, chemical plants, oil & gas equipment, and HVAC units. Typical uses include sealing flanges, pumps, valves, and in various fluid handling assemblies.

Q: What manufacturing processes are employed for HSN/HNBR gaskets?

A: The gaskets are produced using compression molding and injection molding, guaranteeing precise measurements and dependable material consistency for both standard and custom designs.

Q: How does the gaskets ozone resistance benefit long-term reliability?

A: Thanks to excellent ozone resistance (no cracking under continuous exposure), HSN/HNBR gaskets maintain their integrity over many years, reducing the risk of premature failure and the need for frequent replacements.

Q: What advantages do optional stainless or carbon steel rings offer with these gaskets?

A: Incorporating stainless steel or carbon steel inner and outer rings adds rigidity, durability, and improved sealing capability, especially for high-pressure, corrosive, or mechanical stress environments.
