Custom Capabilities

APM Hexseal develops reliable, cost-effective seals to meet your unique application needs. Here are some examples.

Remote Automotive Keyless Entry Control

Sealing Problem: • Seal the perimeter between mating top and bottom component covers. • Seal and color-code three printed circuit board-mounted pushbutton switches. • Provide a transparent viewing window for monitoring the PCB-mounted, battery-status LED. • Render the entire unit submersible.

APM Design Solution: A single-piece tri-color (black, green and clear) silicone rubber seal, geometrically-contoured to the control’s housing and internal electronic components. The seal, housing and circuit board are held together by one of APM HEXSEAL’s patented, reusable self-sealing fasteners.

Outdoor Audio System Keypad

Sealing Problem: • Seal and protect keypad from all kinds of weather conditions, dust, dirt, moisture. • Must tolerate sunlight and exposure to ozone. • Should be a single piece design. • Provide transparent viewing window that permits easy keypad operation.

APM Design Solution: A single-piece seal, precision molded with crystal-clear silicone rubber that nests neatly in a perimeter groove on the keypad’s front plate assembly.

Security System Access Keypad

Sealing Problem: • Geometric compatibility with pushbutton switch array. • Protect keypad from weather, water, dust, dirt and cleaning solvents. • Tolerate sunlight and exposure to ozone. • Provide durable switch identification designations. • Provide excellent tactile feedback of switch actuation.

APM Design Solution: A fitted, single-piece, custom-colored seal molded from a specially-formulated rubber with durable, recessed, high-contrast switch legend markings.

Programmable Digital Panel Meter

Sealing Problem: • Protect DPM’s front programming switches from water, oils, grease, dirt and cleaning solvents. • Permit easy reading of DPM’s switch markings. • Resist discoloring in presence of sunlight. • Not compromise programming ease. • Single-piece design.

APM Design Solution: A full-bezel soft seal fabricated from a special transparent rubber formulation. Form-fit design seals panel cut-out in which DPM is mounted, while permitting operation of the unit’s programming switches through the soft, flexible seal.

Lighted Pushbuttons for Military Aircraft

Sealing Problem: • Prevent penetration of moisture from fog or salt spray. • Tolerate kerosene, alcohol and light detergents. • Ensure pushbutton actuator remains attached to switch body under high-impact shock of up to 1,500 Gs. • Permit actuation of pushbutton. • Permit viewing of lighted indicator and switch legend.

APM Design Solution: A snap-on, single-piece bezel seal consisting of a custom stainless steel frame over which is molded a durable, chemically-resistant elastomer.

Missile Launch Control Circuit Breaker

Sealing Problem: • Protect circuit breaker from weather, salt spray, dust and dirt. • Permit easy resetting of tripped circuit breaker. • Permit viewing of circuit breaker status. • Resist yellowing or other discoloration due to aging or exposure to sunlight. • Meet stringent test requirements of MIL-B-5423.

APM Design Solution: A custom-molded boot made of APM’s proprietary, transparent elastomer (RubRGlas™) and a painted steel frame featuring filled engraved legends. The boot and frame are secured to the circuit breaker using APM’s patented reusable self-sealing fasteners (SEELSKREWS™).

Food Processing Equipment

Sealing Problem: • Meet cleanliness and corrosion-resistant requirements of the food and beverage processing industry. • Protect pushbutton actuator from frequent washdowns. • Provide mechanical advantage to actuate the pushbutton control. • Seal the panel cutout in which the pushbutton is mounted.

APM Design Solution: A unitary pushbutton switch seal assembly consisting of a durable, fluorosilicone rubber boot encased in a stainless-steel actuator housing.

Other industry applications: Equipment for meat packing, dairy processing, fast-food and commercial cooking equipment, pharmaceutical, medical/dental, hydraulic lift mechanisms on trash and other hauling vehicles’ controls, remote crane & locomotive controls, sewage equipment, underwater/marine, agricultural, car wash, and military equipment controls
