Square-Profile O-Rings - Square Cut Rings
Standard AS-568 size Rubber Square Rings can sometimes be used interchangeably in AS-568 standard size O-Ring gland designs. Square Rings can be used in static applications where high sealing load force is required or when the sealing area is too thin to accommodate anything else. In most static applications, it is a direct replacement for an O-ring and generally will perform a high pressure gasket functioning as well as or better than an O-ring. With flat edges on all four sides, square-profile O-rings cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections.
