APM Hexseal has introduced a range of pushbutton-switch sealing boots designed to handle external pressures to 1,500psi (103bar) and temperatures from -80 to +400F (-62 to +204C).

The external actuator mechanism is armour plated with 300 series stainless steel, which protects an internal elastomeric sealing membrane conforming to A-A-59588.

Manufactured to stringent specs of MIL-DTL-5423, it is IP66/68 ingress rated and UL recognised.

These harsh environment specs make it an ideal candidate for extra protection, while converting an unsealed pushbutton switch’s actuator to a rugged sealed actuator.

The Hexseal Switch Boots are ideally suited for use in food, beverage, dairy and meat/fish packing processing plants; pharmaceutical and petrochemical plants; and medical, military, marine and transportation equipment.

They are now available in three versions: p/n 1238/1SS with a 0.75in (19.05mm) diameter head; p/n 1238/5, which features an oversize 1.25in diameter head; and p/n N-1030T toggle-style silicone rubber boot covered with a bonded nickel-plated brass cap.

All boots operate smoothly, even with a gloved hand.

APM manufactures a wide range of high-performance switch, potentiometer and circuit-breaker sealing boots that are compatible with most toggle, pushbutton, rotary and rocker-style actuators.
