Heat Shrink Tubing

[Chris]

I have a digital cable with phono rca plugs at both ends, the cable outer acrylic sleeve barrel is held only to the cable with heat shrink glued tubing, for very expensive cables these have not held very well and have lost it's grip and hold leaving the barrel to depart from the cable.

I have sent a few emails to the manufacturer but have not had any reply, they say they respond between 3-5 working days, first email is more then 3 months ago.

The question is will glued heat shrink tubing reheat so I could slide tight the plugs to the cable?

Last option would to remove the old heat shrink, but this would destroy any re-sale of the cable in the future.

This has put me off buying cable.

Here is a link below on a similar cable being made.

Hi Chris, if it will go back together in the right position it should re-glue with heat. If not cut the old tubing off and re-do it with new shrink tubing.

I use a Black and Decker DIY heat gun (very hot, waft gently and mind your fingers) but for years before that I used the good lady's high power hair dryer up close as the tubing only needs around 90-100C.

Practice on a few bits if you've not used it before. You can get adhesive and non-adhesive tubing in colours and various sizes easily on eBay,

Thanks Richard for your advice, I have recently bought a heat gun after years of using the soldering iron, not the best way, just need to keep things moving and not over heat the cable.

Hi Chris,
Yes as Richard says the glue should remelt but I’ve found adhesive hs needs a lot more heat to melt the glue than for ordinary hs.

I use a hot air attachment to a gas soldering iron (solder pro120), its small and neat but before that I used heat gun. I’ve never found the glue holds well on smooth non porous surfaces tbh but if you can just ease the end up a fraction a few drops of super glue does usually the job. This is how I finish off the cables I make and it holds well on any braided sleeve too

Good luck
Martin

Thanks Martin, the super glue is a great tip.

No, not a hot air soldering gun as used for SMD soldering, you need much bigger, mine's a B & D paint stripper - electric blow torch - like this but a bit older,

I had a message from another user with similar cable and problem:

"The DIN connection was a little temperamental so I asked Chord if they could re-terminate it. They put me in contact with Sonority, who do these kind of jobs for Chord: http://sonoritydesign.co.uk/sonority.../chord-cables/

They added a new DIN last week (£172) so should be as new."

Just buy some shrink tubing and a DIY heat gun and have a practice Chris

No Richard it not a hot soldering gun, it’s a hot air adapter for a gas soldering iron, it only get hot but not hot enough for soldering.
I’ve used it for ages it’s nice and small and very accurate and works fine. It has the advantage of being able to progress up the tubing tubing so you can adjust as you go.

I was replying to Chris' post 3 Martin. There are many ways but get some tube and practice if it's an important job.
