APM Hexseal sealing solutions, including boots and bushings, are designed to protect switches and potentiometers in hostile environments. Hence achieving this without compromising, or interfering with, the unit’s basic operation.

With each seal made from tough, high tear-strength elastomer resistant to most chemicals, lubricants, acids, and solvents. And each remains flexible over a wide operating temperature range ~ with many units rated at -94°F to +400°F. Most toggle, pushbutton and rotary shaft models feature a moulded-in mounting nut. Thus, serving as both a reliable seal and mechanical mounting. In addition, each HEXSEAL® and E-SEEL® features an integral proprietary sealing rib. This serves to seal the panel cut-out in which the component is mounted, protecting behind-panel circuitry from leakage or blow-by. Full toggle, pushbutton and rocker switch boots completely envelop the front-of-panel switch mechanism, providing reliable protection even under high-pressure washdowns. The seal hugs the actuator of the rotary shaft and half toggle/pushbutton (in which the actuator protrudes) giving a snug fit. To say nothing of protecting against entry of moisture, oil, dirt, dust, and other contaminants.

APM Hexseal invented and patented pre-assembled self-sealing fasteners designed to provide both fastening and sealing integrity in a single unit. Their design features a resilient O-ring held captive in a precision-engineered groove under the fastener head. This combination of precise groove geometry and O-ring characteristics results in an absolute seal regardless of surface finish, while still providing full metal-to-metal contact. Vibration-resistant and re-usable, SEELSKREWS®, SEELBOLTS®, and SEELNUTS® can withstand internal/external pressures up to 6,000 psi/vacuum at temperatures from -160°F to +500°F.


Sealing options

All fasteners are available in standard and metric thread sizes. It is possible to formulate the integral seal for compatibility with a wide range of gases and liquids. In contrast to alternate sealing compounds including, tape, chemical coatings, and deformable washers that attempt to seal the thread form, they represent a superior option.

Different sealing compounds include Silicone, Viton, Buna-N and Ethylene Propylene (EPDM).
