Square O-ring cords have a distinctive square cross-section and function as a sealing material in industrial applications that prevent fluid or gas leakage between mating surfaces. The key difference between square ones and round O-ring cords, is that the square ones are ideal for applications with rectangular or square-shaped grooves, and when compressed between two surfaces, it forms a secure seal. Installation is super easy as it just involves placing the cord in the specially designed grooves to create a seal and can easily be adapted and cut to fit various groove sizes in order to provide an effective sealing solution. Square O-ring cords are available in a range of materials like nitrile or silicone rubber, or FKM (fluorocarbon), which provide excellent chemical resistance and durability. Their resilience and customisation make them valuable in diverse industries where reliable seals are crucial for preventing leaks.
