Encapsulated hollow O-Rings

Hollow O-rings are a feasible solution in instances where standard O-rings cannot be used. Hollow O-Rings offer a low closure force alternative to solid O-Rings. As required for many lids and doors, hollow O-Rings are used in applications that require the seal to stay in the groove while not overfilling the gland or warping the enclosure lid or door.

These O-Rings consist of an elastomer inner ring and a seamless sheath which surrounds the elastomer ring. Similar to PTFE O-Rings hollow ORings are used wherever the chemical resistance of normal elastomer O-Rings are not sufficient. The required elasticity is provided by the elastomer ring, the chemical resistance by the seamless sheath.

Advantages of hollow O-Rings are that they are chemical resistant, a wide range of thermal stability, low permeability and low friction. The hollow type of O-Rings are used as sealing elements, as energizing elements for hydraulic slipper seals and wipers and thus cover a large number of fields of application.

Excellent Orings to suit the needs of its customers all across

Sealing requirements can be fulfilled with spectrum of options. The options vary as per specific usage. If you are facing problems with your sealing system, try O-rings sealing solutions and get the best of seals available. As different industries look for diverse variation, there are options to fulfill their demand. O-rings are the finest type available. These O-rings are known for their quality and superior sealing abilities.

O-rings are round shaped rings made out of elastomeric compounds that consists of natural or synthetic rubber. With innovative designing and impeccable engineering, Darcoid offers these excellent O-rings to suit the needs of its customers all across. This is because these are dependable, safe and long-lasting.

These O-rings are being widely in use in industrial sectors ranging from automotive to fluid power to semiconductor processing. O rings are generally being used in cars, construction equipment, heavy duty trucks, refrigeration and air conditioning components, commercial and military aircraft, pharmaceuticals, oil and natural gas rigs, kitchen and bath fixtures, surgical instruments, fuel handling equipment and drug delivery devices and many more applications.

Metal O-rings are the metallic variants of commonly used elastomeric O-rings. They are typically used in static sealing applications that are incompatible with the physical and chemical characteristics of elastomeric O-rings. These O-rings have high tolerance to radiation as well as high vacuum, and are generally used for flanged applications. Ideally, metal O-rings are placed in both open and closed grooves and axial pressure is applied between two parallel surfaces. Furthermore, grooves that hold the O-rings are designed to be perpendicular to the direction of the fluid flow. When placed between surfaces and compressed to a predetermined height, deforms and creates contact between the jointing and sealing faces. Inherently, O-rings' metallic elasticity displays a reasonable deflection and creates maximum sealing contacts during operation to ensure the sealing action. In addition to elastic deflection of the metal, structural builds of the O-rings also play an important role in creating the sealing force. Although most metals can be used for manufacturing metal O-rings, the choice of metals should be such that the linear expansion co-efficient of the O-ring metal varies slightly from the linear expansion co-efficient of the metal of jointing surfaces. Metal O-rings are vulnerable to rusting unlike elastomeric O-rings, and as such, are coated with a suitable material to avoid rusting. This material is softer than the base metal and serves an additional purpose of negating the effect of surface abnormalities. The coating materials that are typically used are soft metals, such as silver, and non-metals like PTFE.

Whether it's the flow of liquid or air, O-rings are exceptionally effective in making the seal highly efficient. The quality of the seal plays a pivotal role and the manufacturers must take extra care while choosing the raw materials and production techniques. With high tech solutions and advanced methods, the kind of sealing devices from Darcoid Nor-Cal Seal are immensely satisfactory and offer desired results every time the product is used for varied industrial usage.

All industries right from mechanical, automotive, pharmaceuticals, and many more choose O-rings for their usability. With years of experience and first rated facilities provided by Darcoid Nor-Cal Seals, their O-rings have witnessed tremendous rise in their popularity. The O-rings are the most preferred options for engineers across the world for all their sealing needs.

Broad range of products in Electro Magnetic Interference shielding applications

EMI shileding gaskets have proved its immense worth in the electronic industries. Today, huge challenge is faced when it comes to designing and manufacturing of electronic devices or equipments for the consumer or business markets. With increase in demand and need for perfect devices complexities have increased as these devices are more inclined to electromagnetic interference. With advent of Electromagnetic shielding or EMI these complexities have been resolved but has not so far proved its worth. These shields usually implemented in a design isolate component or section of a device from one another and therefore need of these gaskets are vital.
EMI shileding gaskets are best for controlling undesired electromagnetic energy and radio frequency interference from disrupting or radiating from electronic devices. Their availability in different shapes, sizes and configurations make them highly demandable. Various types of gaskets are available in the market to provide different levels of shielding effectiveness across the frequency range. Best fit for different operating environment they meet customer specific requirements. They can be installed using pressure sensitive adhesives, fasteners or epoxies or by press - fitting into groves. In fact some gaskets can be molded in place on the enclosure flanges or on a plastic spacer frame. Chemical milling has also become a need of electronic, industrial and commercial units where removing heavy metals from the defined object seemed to be a task of great effort.
In order to compete in the world of technology it seems important to equip all devices with EMI shielding. Availability of EMI shileding gaskets have almost resolved this issue and had standardized products for all time usage. In order to ensure long term functionality to the devices and equipments these gaskets play a vital role.
