Abstract: Studies were made to develop rubber seals suitable for use on wheel- and roller-mounted gates operating under high heads. During the closing cycle under unbalanced pressure conditions, the seal bulb tends to be pinched between the seal clamp and seal seat. Six factors affecting this pinching were varied in an attempt to find the optimum seal assembly. Eleven double-stem seal designs, utilizing different combinations of fluorocarbon and brass cladding and rubber compositions, were tested at heads up to 600 ft (182.88 m). The tests were conducted in a special test rig which accommodated full-size seal specimens, 12-1/8 in. (30.798 cm) long. The tests included measuring the seal bulb extension, and photographing and observing the general behavior of the seal under load during opening and closing cycles of the gate.
