APM Hexseal
Silicone External Rotary Shaft Seals
APM Hexseal
HexSeal External Rotary Shaft Seals are molded from a high tear-strength silicone rubber 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.

The external shaft seal will increase the amount of force required to rotate the shaft.
