Molded Rubber Products

An O - Ring is a circular band with circular cross section to arrest leakages between two faces or over shaft and hole. They are designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

O–Rings selection is based on chemical compatibility, service temperature, sealing pressure, lubrication requirements and working atmosphere. Successful o-ring joint design requires a rigid mechanical mounting that applies a predictable deformation to the o-ring.    

This introduces a calculated mechanical stress at the o-ring contacting surfaces. As long as the pressure of the fluid being contained does not exceed the contact stress of the o-ring, leaking cannot occur. The seal is designed to have a point contact between the o-ring and sealing faces. This allows a high local stress, able to contain high pressure, without exceeding the yield stress of the o-ring body.

The flexible nature of o-ring accommodates imperfections in the mounting parts. Mostly these O Rings are used to seal hydraulic, pneumatic and wherever sealing is required. We manufacture O-rings, seals and associated components from a wide range of materials, with the shortest lead-times in India.    

When mismatching the sealing line and parting line, the sealing performance is improved due to the flash marks. Because there is a mechanical removal of flash is taken place in the sealing line.

The offset parting o-rings is widely used in critical applications. These o-rings are costlier than regular O-rings, because of their construction.

Our continual investment and development of product, personnel and customer satisfaction ensures we remain unrivalled in our field for quality and service.

Grommets are generally flared or collared on each side to keep them in place, and made in various polymers depending on the application. They may be used to prevent tearing or abrasion of the pierced material or protection from abrasion of the insulation on the wire, cable, line being routed through the penetration, and to cover sharp edges of the piercing, or all of the above. These are also use in Irrigational sector for Drip Irrigation. We are also one of the largest Suppliers of Drip Irrigation Rubber Grommets.

Most common are molded rubber that are inserted into small hole diameters up to 2" in diameter. There are many hole configurations from standard round to assorted U-shapes. Larger penetrations that are irregular in shape as well as long straight edges often use extruded or stamped strips of continuous length. These Continuous length materials are referred to as "grommet edging".

These are quite common in applications that range from telecom switches and data center cabinets to complex and dense wire/cable and even hydraulic tubing in aircraft, transportation vehicles and medical equipment.

Grommets are also manufactured from over 15 polymers including:  Nitrile / Buna-N (NBR), Fluorocarbon (Viton®, Fluorocarbon (FKM), Silicone (VMQ), Fluorosilicone (FVMQ), Polyurethane (AU/EU), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (HNBR), Styrene Butadiene Rubber (SBR), Chloroprene (Neoprene®), etc

Filter Gaskets are especially used in Drip Irrigational Filters and available in different sizes and dimensions according to size and design of filters. Filter Gaskets are usually manufactured using Natural Rubber (NR), Ethylene Propylene (EPDM) where EPDM is best for its environmental stability as it sustains in all types of weather conditions, salts, minerals, water, UV radiations, etc. Natural Rubber is used for cost effectiveness and its tensile strength.

In the calendering process, fabric and rubber material is passed through a series of rollers to flatten, smooth and commingle the two or more materials. Calendered sheets can have multiple layers of both the elastomeric and polymer "sandwiched" together.

Sheeting produced by the calender process is typically divided into two classes: either fabric inserted, or unsupported. Unsupported calender goods contain only layers of rubber or plastic that have been joined without cord, cloth or textile being inserted for strength or tear resistance. Tire cord can be used special cases; rayon, cotton, nylon, or polyester cords are arranged in parallel and bound together by rubber on a calender.

Depending upon intended use and required look or feel, the sheets of rubberized fabric are then smoothed, glazed, polished, or given a moiré or embossed surface. The resulting surface characteristics depend on the pressure exerted by the rollers, on their temperature, composition, and surface designs, and on the type of coating or glaze previously applied to the material to be calendered. Following the calendering process the material is then wound into rolls and placed into storage.

Rubber Hose: A hose is a flexible hollow tube designed to carry fluids from one location to another. Hoses are also sometimes called pipes (the word pipe usually refers to a rigid tube, whereas a hose is usually a flexible one), or more generally tubing. The shape of a hose is usually cylindrical (having a circular cross section).

Hose design is based on a combination of application and performance. Common factors are size, pressure rating, weight, length, straight hose or coilhose, and chemical compatibility. Hoses are made from one or a combination of many different materials. To achieve a better pressure resistance, hoses are reinforced with fibers or fabric material.

Hoses are manufactured from over 15 polymers including:  Nitrile / Buna-N (NBR), Fluorocarbon (Viton®, Fluorocarbon (FKM), Silicone (VMQ), Fluorosilicone (FVMQ), Polyurethane (AU/EU), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (HNBR), Styrene Butadiene Rubber (SBR), Chloroprene (Neoprene®), etc. Most commonly used in automobile sector, chemical and water treatment plants, Irrigation sector, Pharmaceutical and food processing industry, etc.

A diaphragm seal is a flexible membrane that seals and isolates an enclosure. The flexible nature of this seal allows pressure effects to cross the barrier but not the material being contained. Diaphragms are also used to protect a process fluid from the pressure sensor.

The reinforced membrane transfers energy and separates two medium.

• Works under two different pressures / liquids / gases.
• Transfers pressure from one side to another.

Selection Parameters :
