FASTENER FACTS: THREADLOCKING

Unlike liquid anaerobic sealant threadlockers, all APM threadlocking enhancements are reusable and can be adjusted in one hour, one day, one year and beyond.  APM self sealing fasteners with optional threadlocking is  a clean, dry system.  No chemical fumes for employees to inhale and no environmental disposal issues.  When liquid threadlocked fasteners  require adjustment, they must first have their seal broken and threads cleaned before reapplication; a long and tedious operation.

AIR-BOAT INSTRUMENT PANEL SWITCHES
STAY DRY

Typically, most people are accustomed to seeing this type of rescue air-boat in the Florida Everglades and various coastal waterways. Surprisingly, they can also be found operating on northern lakes that experience winter freeze-ups. They can be seen skimming over ice and water — making daring rescues throughout the year. In extremely difficult environments such as this, reliability is always an issue. Each boat instrument panel is equipped with eight toggle and nine clear circuit breaker silicone sealing boots.  APM originally developed boots for the U.S. Navy for protection against every imaginable marine condition — from corrosive salt-air to salt spray to fungus and lubricant penetration. Today, millions have been installed throughout the world, from multi-million dollar yachts, the most advanced fighting ships  and oil rigs to small pleasure boats.  Since the end of WWII,  going to sea without these seals has not been an option.

UNDERWATER & OVERWATER ROBOTIC CONTROL CONSOLS NEED EXTRA RELIABILITY

ROV — REMOTELY OPERATED VEHICLES  are the real heroes of underwater inspection and maintenance  operations. A recent example is the  Gulf of Mexico, BP oil rig fire and failure. We all experienced the dragged out,  excruciating events on our TV screens. We saw the difficult, challenging repair work performed by ROVs, each remotely operated by a skilled technician interacting with a joy stick and variety of toggle and adjustable, rotating switches. These shipboard mechanical control consoles maintain their reliability because they are environmentally protected by APM’s HEXSEAL® sealing boots from salt air corrosion, water, fungus, ice, dust, dirt, grease, cleaning solvents — just about anything  that comes it’s way. Known for their ruggedness and ability to handle temperatures from – 94°F to +400°F (-70°C to +204°C) and ingress rated to IP66/68.  UL Recognized, meeting MIL-DTL-5423 Specifications and RoHS Compliant.

NIGHT VISION GOGGLES NEED TO BE HELD TOGETHER IN ALL KINDS OF HOSTILE CONDITIONS

Whether operating on the ground, in high altitudes, or in high-pressure submersible conditions — night vision goggles not only have to be reliably sealed, they need to be field-maintenance friendly. Thats why leading night vision equipment manufacturers have selected APM’s high-pressure self-sealing SEELSKREWS® to do the job. Because of the patented O-Ring embedded design that captures the O-Ring in an asymmetrical groove (located under the screw’s head) — a perfect metal-to-metal seal is achieved. The design also affords multiple reuse without appreciable degradation to the silicone O-Ring, whether operating in wet, dry, dirty or dusty environments. Unlike anaerobic threadlocking liquid sealants, these fasteners are easy to remove and reuse. It’s a fast one-step process — no chemical fumes to breathe, no environmental disposal problems, no primers required (therefore no curing time), no special training required regarding location or number of drops, etc.
