Cisco IP Phone Ring Cord – Technology Bazar

The ring cord is a versatile and practical solution for creating custom O-ring seals when pre-made sizes are not available. Made of flexible elastomeric materials such as nitrile (NBR), silicone, EPDM, Viton (FKM), or other specialized compounds, it features a consistent circular cross-section and is typically supplied in coils or by the meter.

To form a seal, the cord is cut to the required length and the ends are joined using adhesives or heat-vulcanization techniques, producing durable rings suitable for both static and dynamic sealing applications. Its flexibility makes it ideal for irregular grooves and larger diameters that standard O-rings cannot accommodate.

Ring cord is widely used across industries. Silicone variants are common in food processing and medical equipment due to their high-temperature tolerance and non-toxic properties. EPDM is well-suited for HVAC and plumbing, while Viton offers excellent chemical resistance and performance in high-temperature environments. Additional benefits include simplified inventory management—since one stock item can create many custom sizes and reduced material waste, supporting efficient and eco-friendly manufacturing practices.
