on O-ring drive belts and their application will be found in O-Ring Applications, Section III. 1.2 What is an O-Ring Seal? An O-ring seal is used to prevent the loss of a fluid or gas. The seal assembly consists of an elastomer O-ring and a gland. An O-ring is a circular cross-section ring molded from rubber (Figure 1-1).

specifying O-ring and groove dimensions for static applications with pressures less than 1500 psi. The guidelines are for the nominal condition. The minimum and maximum conditions should also be checked. This requires looking at the dimensionally largest possible O-ring in the smallest possible groove (i.e., at the hardware
