WCSM Sizing Change

     WCSM Heavy Wall Sealant Coated Tubing has recently gone through a sizing adjustment.  In almost every case, this is an incredibly minor change as the tubing has simply been expanded a little bit more and re-named.  In every case the tubing recovers down to the very same dimension.

What used to be WCSM 9/3-1200-S is now WCSM 12/3-1200-S 

This simply means that the WCSM shrink sleeve used to be supplied with a 9mm ID (.354")

but is now supplied with an ID of 12MM (.47").  

This change has effectively modified this WCSM (and all WCSM sizes) to cover 

a larger range of wire and connector sizes.

What used to be WCSM 13/4-1200-S is now WCSM 16/4-1200-S 

This simply means that the WCSM shrink sleeve used to be supplied with a 13 mm ID (.51") but is now supplied with an ID of 16 mm (.629")

 What used to be WCSM 20/6-1200-S is now WCSM 24/6-1200-S 

This simply means that the WCSM shrink sleeve used to be supplied with a 20 mm ID (.787") but is now supplied with an ID of 24 mm (.94")

What used to be WCSM 33/8-1200-S is now WCSM 34/8-1200-S

This simply means that the WCSM shrink sleeve used to be supplied with a 33 mm ID (1.299") but is now supplied with an ID of 34 mm (1.338")

What used to be WCSM 43/12-1200-S is now WCSM 48/12-1200-S 

This simply means that the WCSM shrink sleeve used to be supplied with a 43 mm ID (1.692") but is now supplied with an ID of 48 mm (1.889")

 What used to be WCSM 51/16-1200-S is now WCSM 56/16-1200-S 

This simply means that the WCSM shrink sleeve used to be supplied with a 51 mm ID (2.00") but is now supplied with an ID of 56 mm (2.20")

What used to be WCSM 70/21-1200-S is now WCSM 70/20-1200-S 

In this case, the change means that the WCSM 70/20, when fully recovered 

is 1 mm smaller at .787" instead of .826"

What used to be WCSM 105/30-1200-S is now WCSM 110/30-1200-S 

This simply means that the WCSM shrink sleeve used to be supplied with a 105 mm ID (4.13") but is now supplied with an ID of 110 mm (4.33")

What used to be WCSM 130/36-1200-S is now WCSM 130/35-1200-S

In this case, the change means that the WCSM 130/35, when fully recovered 

is 1 mm smaller at 1.377" instead of 1.417"

WCSM 24/6-1200-S IN STOCK 6/28/13

     I understand that through some kind of unlikely chain of events, the plant is currently unable to supply WCSM 24/6-1200-S for 5-6 weeks.  I can also understand what a huge problem this can be for many customers out there.

     We currently have this part available and ready to ship.  Actually, we have the previous size (WCSM 20/6-1200-S) available to ship (I think I have ~1800 pieces - all 4 feet long; so 7200 feet of material).

     The only difference between the WCSM 24/6 and the WCSM 20/6 is that the 20/6 is supplied with a 4mm smaller ID.  It will still work exactly the same and shrink down to the same wire sizes.  WCSM 20/6 was the standard part for many, many years until Tyco decided to supply the tube a little larger a few months back.  So - call us today - 936/321-3333 for a quote.

Raychem Elite Distributor

     Joint Specialists is an Elite Distributor for Raychem heat shrinkable products.  This means that, due to our high volume buying history, our product commitment, our product expertise and our financial commitment to keeping a stock of Raychem material on hand; we are treated as a valued piece of the world wide Raychem shrink sleeve distribution network. 
 
     Unfortunately, there are a lot of "resellers" out there who do nothing more than attempt to act as a commodity broker; offering anything that any customer might request.  We do not believe this is the best way to run a business - and we do not believe this sort of approach will truly benefit the product line (or the customers) over the long term. 

     It is really incredible to hear the shock in someone's voice when they have called us requesting pricing on a part.  The conversation might go something like this:

Customer:  "Wait, you know what I'm talking about?? You've heard of this product?"

Joint Specialists:  "Yes, we stock that product.  I've currently got 2000 sitting on the shelf."

Customer:  "Are you serious!?!  I've been looking for this stuff all over the place and no one has ever even heard of it."

Joint Specialists:  "Well, I've got it right here and I can ship some out today..."

Customer:  "Oh man; I wish I'd found you two weeks ago!"

     So, what are you waiting for?  Call us today.  Let us help you.  Let us make your life easier.  Let us save you headaches and problems.  Let us get your material on its way to you so that you can focus on the other 47 items you're trying to track down!
