Rotary Shaft Seals for Switches & Potentiometers

HEXSEAL® and E-SEEL® rotary shaft seals are molded from a high tear-strength silicone rubber (other materials

available for specific environments) bonded to a built-in mounting nut. Each seal surrounds the rotary shaft and forms a

watertight and dust-tight seal against the shaft and front panel surface.

HOW TO ORDER

Specify APM boot part number and, if necessary, the appropriate bushing

adaptor part number (please see page 19).
