Recommended Retainer Groove

For circular, radial expansion inward/outward configurations, especially smaller diameters, an inflatable bladder can be sized so that their tension or compression forces are generally sufficient to hold them in place within a groove. If used in other configurations, adhesives are generally required.

RW = seal profile width (w dimension) with its plus tolerance

RH = seal profile height (H dimension) with its plus tolerance

Surface finish of bottom of machined groove should be 63 microinch or better with finish lay parallel to seal.
