Title: Shrink-Wrap Tubing Question
Post by Digger on 06/07/09 at 19:16:09

I need help.

I'm filling out a McMaster-Carr order. I wanted to get some heat-shrink tubing to replenish my stocks.

There are many different types offered:

I'll be applying heat with a 1400 watt heat gun.

Of the huge selection offered, what type would you recommend for work on motorcycles, including dual-purpose bikes?

Here's what I've drilled down to so far (correct me if I've gone astray):

TYPE: Adhesive-Lined (Moisture Seal) ---> MATERIAL: Flexible Polyolefin ---> POLYOLEFIN TYPE: Standard ---> SHRINK RATIO: 2:1.

Remember, I'll be using a 1400 watt heat gun to apply the shrinking heat.

TIA!

What? You mean I could have been getting PECANS in my waffles? Who knew?

I had no idea there were so many kinds of heat shrink tubing. Ive been getting a cheapo pack, no adhesive, just a shrinking tube, ( no comments, please) from Harbor Freight.

My application method is a bit more advanced than yours, tho Digger. I use a cigarette lighter. Its portable, requires no AC voltage, fits in my pocket. I had no idea people used heat guns for it. Now I gots ta have me some!

Pretty much anything that doesn't get super hard, or is really thin will work great.

I've used the standard type, and now only use the moisture seal type. The standard type does not seal out everyday humidity and allows the wire connection to corrode green. I found this out by noticing green corrosion at the ends of the shrink tube on one of my cars. Upon removing the tubing, I found the copper wire to have green corrosion. It is also important to clean your solder joint well before you shrink tube it, and now in addition to this, I spray a little " Deoxit D5" on the solder joint and bare wire before I shrink tube it. Deoxit D5 is expensive but a top of the line product for protecting from corrosion on electrical connections. This combination has lasted for years for me, with no corrosion.

Gort,

Thanks for the data dump.....I'm good to go now!

I've got some De-Ox-Id (http://www.altex.com/GC-Waldom-De-Ox-Id-Contact-Cleaner-4oz-Aerosol-19-1906-P141839.aspx) sitting on the shelf. Do you think this stuff would work?

I read the description of your De-Ox and its just what you need. De Ox is expensive but a real quality product.

Digger: As a long-time electrical/electronics worker both pro and hobby, I can tell you that you are absolutely on the right track with both products:
The shrink wrap I prefer for anything that goes outside includes the plastic sealant that squishes out the ends, for the reasons already stated. And the Caig's DeOxit and other products are the #1 choice of serious Pro audio and music instrument amp repair guys. It's worth the extra expense in the parts it can salvage and time saved!

Ive never seen these high quality shrink tubes. Where should I be looking?

Gort, Thumper, Rockin - thanks for sharing your knowledge.

Justin - I'm getting some from McMaster-Carr (http://www.mcmaster.com/#heat-shrink-tubing/=291by0) just to fill out an order.

Someone on my Gold Wing board recommended these guys for quality wiring stuff: Pacer Marine (http://www.pacermarine.com/)

A guy on my KLR forum recommended this stuff: Sumitube (http://easternbeaver.com/Main/Elec__Products/Shrinktube/shrinktube.html)

I'm sure there are LOTS of other good suppliers.
