Rotary Shaft Seals

APM's HEXSEAL rotary shaft seals for potentiometers are designed to meet the same specifications (MIL-DTL-5423) as APM's toggle and pushbutton sealing boots for addressing harsh environmental conditions. Models matching most popular rotary switches and potentiometers with standard/metric bushing threads are available. All feature a molded in mounting-nut for simple installation. Choice of IP66/68 rated models that also include boots for locking rotary shaft styles, and sealing boot versions that will also suppress emi/rfi spurious signals, are also available. All are UL Recognized components and used extensively in marine, medical, military, aviation, automation, instrumentation and construction equipment, including process and varied industrial plant applications. Made in the USA.

HEXSEAL and E-SEEL® rotary shaft seals are molded from a high tear-strength silicone rubber (other materials available for specific environments) and 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.
