APM HEXSEAL was founded in 1947 with the mission to develop and
manufacture environmental sealing solutions to protect and
prolong the life of electromechanical switches and circuit
breakers in hostile environmental conditions around the
globe. This focused effort resulted in the development of an
extensive line of standard silicone sealing boots that are compatible with the vast majority of switches, breakers, encoders,
potentiometers and rotary devices used throughout the world
today.
Complimentary sealing products were soon
developed and patented, including a complete line of reusable, self-sealing fasteners,
and silicone colorizing incandescent lamp filters that transmit colors for instrument panels
and lighted pushbutton switches.

APM Hexseal Boots for Toggle, Pushbutton
& Rotary Switches
Any unsealed electrical devices mounted to a control panel or piece of electrical equipment can
fall victim to the impacts of hostile environmental factors if not properly protected. In this
context, “environmental” is a very broad term, encompassing any number of possible factors,
including weather conditions like rain, snow or prolonged wind and sun exposure, pressure
changes from submersion in fluids or changes in altitude, contaminants such as water, ice, salt,
air, dust, dirt, grease, chemicals, and even spilled beverages.
APM Hexseal's Sealing Boots are designed to protect the vulnerable areas of a device, and
create a seal against the mounting panel, providing strong protection for the device itself, and
for the overall function of the system.

APM Hexseal Bushing Seals
For Switch Panel Cut-Outs
Bushing Seals pack all the sealing power of a boot, but
focus on the mounting hole as opposed to the switch itself.
Installed before a switch locking nut, the bushing seal fits
snugly against the mounting panel, sealing the mounting
hole from any possible intrusion. Bushing Seals are small,
inconspicuous and perfect for already sealed toggle, push
button and rotary switches.

APM Hexseal Boots for Circuit Breakers & Rocker Switches
Circuit breakers perform a very valuable role in all sorts of control systems, protecting equipment from short circuits and electrical overloads. APM Hexseal’s leveractuated circuit breaker boots are designed to protect these critical devices, extending breaker life-spans and in turn helping to ensure long-term security of the
system as a whole. Molded from APM Hexseal’s transparent silicone RUBRGLAS®, which is specially formulated to maintain clarity and prevent yellowing over time,
these boots allow for easy device operation and status recognition while maintaining APM Hexseal’s exceptional environmental
protection from weather exposure, wash downs, salt water, lubricants, solvents, dust, dirt, grease and any number of other
environmental elements that could potentially threaten electrical components. Our two distinct boot styles are
Back-of-Panel, secured behind the breaker mounting panel, and Front-of-Panel, mounted to the outside of a
panel using a sturdy metal frame. Both styles are secured using APM Hexseal’s self-sealing Seelskrews.
Much like our Circuit Breaker Boots, APM Hexseal’s Rocker Boots are often molded from transparent
silicone RUBRGLAS® which makes for easy viewing of the switch position. The majority of our Rocker Boots
do not include an insert or frame, and are designed to install on the switch prior to the switch installation.

APM Hexseal’s High-Pressure
Self-Sealing Fasteners
MATERIAL SPECIFICATIONS
For APM Hexseal® Standard Seelskrews® & Seelbolts®
Screw/Bolt Material: 18/8 Stainless Steel, passivated (other materials available)
Thread Class: Imperial— Class 2A ; Metric— Class 6g
O-Ring Elastomer: Silicone conforms to A-A-59588, Class 2, GR60 or GR70, Red
Temperature Range: -80° F to +425° F ( -62° C to +219° C)
Pressure Range: Up to 20,000 psig internal and external (subject to clearance
hole dimensions).
Resistant to: Splash, salt spray, sunlight, ozone, weather, fungus, dust, and most
acids and lubricating oils.
Shelf Life: Excess of 25 years.
Enclosure Protection: IEC IP66 / IP68
APM Hexseal holds the notable distinction of having designed and patented
the very first self-sealing fasteners, which became our trademarked
Seelskrews® and Seelbolts®. In addition to fastening, our self-sealing screws
and bolts offer a reliable and reusable seal, preventing (or containing!)
contamination from dust, air, water, lubricants and other liquid or gaseous
substances. They are also vibration resistant, making them a great choice
for applications that encounter day-to-day jarring, or repetitive movement.
Should you need a more serious level of vibration resistance, our screws
and bolts are available with locking features such as self-locking pellets,
strips and patches. Some additional customizations include specialty threadforming variations, tamper-resistant drives, thread captivation, as well as
paint and finish options. Contact us for additional thread size and o-ring
elastomer options.
Standard for stock screws and bolts.
Alternative o-ring elastomers are available by request. (See table on page 7 for options.)
A dual IP code rating indicates that both ratings apply.
APM Hexseal’s UL and ULC Recognized Components conform to UL Standard 50.
Contact us for a complete list of our Recognized Components and ratings.

APM Hexseal’s High-Pressure Self-Sealing Nuts
APM Hexseal's Seelnuts® are made from high quality rubber, molded into a specially shaped cavity in the
nut itself. With threads molded directly into the rubber, these self-sealing nuts form a positive seal along the
threaded section of the Seelnut, as well as with the contact surface, removing the need for gaskets, sealing
compounds or extra surface preparation. Seelnuts install just like conventional nuts, and are designed for
use with ordinary screws, bolts and studs, making them a quick and easy sealing option for all sorts of
applications, especially where there is a need to withstand high internal or external pressures. Seelnuts
are also reusable, meaning that they can be easily removed and reapplied, reestablishing the same
reliable seal when torqued. Our Seelnuts are available in all standard thread sizes as well as a variety of
different elastomers to suit your application needs. For applications where excessive vibration is an issue,
Seelnuts can be supplied with self-locking pellets.

APM Hexseal Air-Tight Sealing Washers
APM Hexseal’s Seeloc® Washers consist of molded silicone rubber bonded to specially formed stainless steel washers.
Designed to be used in conjunction with conventional screws, bolts or studs, Seeloc Washers are a simple sealing solution
that is ideal for all sorts of applications, especially where spray, vapors or wash-downs are present, or where there is
concern of contamination from dust, oils or salt build-up. The silicone contact surface features a continuous ridge which,
upon compression, creates a 360° sealing barrier around the periphery of the washer face. The silicone rubber also forms
a seal under the head of the associated fastener and makes full vertical contact with the threads/shank, making for a complete,
high-pressure seal unlike any other. Seeloc Washers can be used over conventional mounting holes, extra-large holes, or even oddly
shaped adjustment slots. Their reusability make them perfect for applications that might require periodic maintenance or adjustments.
