How to Use Heat Shrink End Caps

Everybody likes to have closure.

From work to home and relationships to jobs, we all prefer nice, clean endings. When it comes to worksite applications, the simplest and most effective closures happen when you use heat shrink end caps.

These heavy wall, adhesive-lined caps are designed to melt and bond to terminations of all sizes, giving you extra protection and the most secure closure possible.

Heat shrink end caps are the fastest, easiest way to get closure for all your on-the-job needs.

What are Heat Shrink End Caps for?

End caps are mainly used to seal off wires, pipes, and cables. They can be used on anything with a cylindrical end that needs to be securely sealed and protected.

Like other types of dual wall heat shrink, end caps are specially lined with hot melt adhesive interiors. They can bond to plastics and metals, and are made from dual-wall polyolefin with rugged exteriors of EPDM rubber. This highly specialized, synthetic rubber is intended for the construction and automotive industries. Products made from EPDM rubber last at least 50 years, are highly elastic, and withstand extreme weathering.

End capping is important for storage and installation needs across many different industries. From insulation to shielding against environmental contamination and abrasion to reducing snags and hazards, end caps are quick, easy, and effective.

Heat shrink end caps come in both hot and cold shrink varieties.

Cold Shrink End Caps

Cold Shrink EC-Series End Caps are made to affix to diameters of 13mm to 70mm. They don't require any training, which allows for very fast installations. Cold shrink end caps are available from BuyHeatShrink.com in 20mm, 28mm, 47mm, and 80mm sizes. They resist fungus, ozone, acids, and alkalis. After end caps are melted and applied, your substrates are covered from any unwanted physical contact for years to come.

Hot Shrink End Caps

Hot melt heat shrink end caps have a 3:1 shrink ratio. Only six sizes are required to cover diameters from 0.16in to 5in. Ends can be sealed with special long or nipple tips and all diameters offer high di-electric insulation and sealing properties.

Hot shrink ends have an initial activation temperature of 120-135C. When heated, the adhesive lining inside each cap begins to melt down. After 2 to 3 minutes, the outer jacket shrinks while the inner wall melts and flows into the newly capped end. This creates environmentally sealed and electrically insulated connections.

As ends cool, the seal from heat shrink end caps becomes pressure tight. Properly installed heat shrink end caps have a continuous use temperature of 110C. This type of end cap is mostly commonly used for capping power and communication cables to establish long-term storage with fortified ends.

Why do I Need Heat Shrink End Caps?

End caps provide a much cleaner and simpler way to get permanent, flexible, and water-resistant barriers on ends that may be difficult to seal otherwise. For hassle-free installations without awkward tapping or inconsistent coverage, end caps are your most reliable method of sealing and safeguarding your projects.

Prevent ends from snagging, keep cables and cords free from debris, lock out dirt and moisture, and lock in ends that stay close and closed.

Extra Protection for Practical Applications

Since end caps provide specific and extra protection, the hot melt adhesive takes longer to fully melt and activate than normal heat shrink products. Apply heat with a heat gun or specialized butane torch for 2 to 3 minutes to ensure complete and proper application.

No matter what environment your end caps are exposed to, hot melt adhesive-lined interiors and rugged EPDM rubber exteriors create the best protection available. Safely capped ends are guarded against exposure to chemicals, UV radiation, common fluid solvents, and other environmental hazards.

End caps give perfect water-tight seals against moisture and weathering. Here are a few practical applications where you can get the most from hot or cold heat shrink end caps.

• Fiber optics
• Automotive
• Generators
• Aerospace engines
• Conduits
• Crimped conduits
• Networking cables

End caps can also be used to close off de-energized or dead cables and out-of-service wires.

When you need to keep ends safely sealed against adverse environments and liquids, heat shrink end caps offer the sturdiest protection around.

End Caps for Your Battle Ropes

Although end caps are typically used to seal off cables and wires for installation and storage, they also are a huge compliment to battle ropes.

Battle ropes have become ubiquitous thanks to CrossFit and television shows like The Biggest Loser. They increase muscle tone and stamina and quickly burn fat and calories. Personal trainers, fitness clubs, home gyms, and more have turned to battle ropes for high-quality workouts.

Battle ropes are durable and thick, typically around 1.5in to 2in in diameter to accommodate the natural grip of human hands. Battle ropes with specialized grips and handles are more expensive to buy than regular ropes. Gyms and home users are often willing to shell out extra money for these more workout-centric types of ropes.

When you're looking to purchase battle ropes for your home or gym you can avoid bulky screw-in aluminum handles, slippery, inefficiently tapped ends, and overpriced specialty ropes if you just apply heat shrink end caps to any size rope you need. Simply purchase the appropriate lengths of rope with 1.5-2in diameter ends and wrap the ends with heat shrink end caps.

Applying heat shrink end caps to rope ends will wrap them with smooth-to-the-touch polyolefin to stop fraying and protect users' hands. Create lifelong handles on any rope you want and guarantee that only calories get burned and not your palms.

Close All Your Lose Ends with Heat Shrink End Caps

From pipes and wires to cables and conduits, the most reliable method to seal out and seal off all the cylindrical ends in every workplace is with heat shrink end caps.

Whether you're working with electricity or working out your core with battle ropes, heat shrink end caps deliver a level of protection unlike any other ending. Close off de-energized lines, limit leaks, shield against debris and contamination, store lines securely, and end worry once and for all with the exacting fit from end caps.

Heat shrink end caps create an insulating barrier that remains in place as long as you need it to. Get the strongest closure and the cleanest ends around only with heat shrink end caps.
