Hi everyone. I'm trimming out the structured wiring in my new construction house. I have two thick HDMI cables in my wall from Blue Jeans Cable that I'm attaching to Leviton HDMI QuickPorts (female-female coupler). Due to the difficulty in bending the thick HDMI cables in the wall, I purchased 8" HDMI "Port Savers" from Monoprice to make the curve needed to connect to the wall plate. The connection from the Port Saver to the HDMI QuickPort is solid enough, but the connection between the Port Saver and in-wall cable is not, and I'm concerned the connection will fall out after I put it back in the wall.
-Any suggestions on how to hold these two cable ends together for years?

My current plan is to use 1" heat shrink tubing over the connection. However, I have little experience with heat shrink and HDMI.
-Do I need a heat gun for a piece of tubing that large, or can I use a lighter or a blow torch?
-Will the heat needed to shrink the tubing be damaging to the HDMI cables or connections?
-Most importantly, will the heat shrink be able to hold the connections together permanently?

Any input appreciated. Thanks!

I don't like using ports and connectors for HDMI, anyone of them can introduce variables that will make the cable useless. I prefer to use something like these http://www.amazon.com/Arlington-CE1-1-Recessed-Cable-1-Gang/dp/B002W6ZPXM and plug them directly into the source or display.

While I understand your logic, I believe these cables are far too heavy and inflexible to be connected directly to the equipment. Even in my limited experience with HDMI, I have already encountered cases where HDMI ports on equipment have had to be replaced because a cable that was too heavy and inflexible was attached directly to them. Nevertheless, thank you for your suggestion.

Do it right and buy a heat gun. Open flame will burn the insulation. And yes, the heatshrink will hold the connections together.

Thanks! Any recommendations on a heat gun? Brand? Temp range?

A lighter will do just fine.
Just move it around constantly. The heatshrink shrinks pretty fast, you will see it happen.

A hair dryer will probably do the job. There isn't a whole lot of difference between a hair dryer with a given wattage rating and a heat gun with the same rating.

I was going to mention duct tape. But if you want it to look more elegant, heat shrink and a lighter should do the trick. smile.gif

I would bring the cable to the equipment, and avoid patching, even with the thick cable.

I've never used one but HDMI port locks are available.

I don't think any hair dryer gets that hot. That would be a liability if it did. My heat gun will melt solder.

It doesn't take much heat to shrink heat shrink. I've never used a hair dryer to do it though, but it'd probably work. And it's definitely safer near carpeting than a match or butane lighter. Give it a go!

(Then again, more people probably have lighters and matches than hair dryers. I could be wrong, though.)
