Anything wrong with using 8mm New England Tec cord for a VT? Its the only thing i can find at the moment. Just wondering if it will do for now until i order a new Eye & Eye as the one i have is sketchy at best... Thanks in advance!

Playground Hero, are you talking about the 8mm HRC from New England? If that's the case,you should not worry about it,because it has a combination of Technora and Nomex which are extreme heat and abrasion resistance.
 
I don't know? I will have to phone and check... i need to use it tomorrow i guess i will back the VT up with a eight or maybe just use the stop i have (sucks though) i don't like pulling rope through it has to much friction... any who i will figure something out... dont want to melt it and fall out of the oak...

Trotac man Trotac. If all you have is 8mm accessory cord then I'm sure that will be fine for a day. Just be careful not to burn it out like others have stated. Worst case scenario just tie a blakes with the tail of your line. Not the smoothest but it's safe

It should be pointed out the NERopes does NOT SHOW AN 8mm size!
What makes you believe that the nonexistent cord is what you have?

Product Description:
Our super strong Tech Cord has a smooth polyester cover over a bulletproof core of 100% Technora. The parallel core design of this rope maximizes the tensile strength of this product.

If used in your climbing system, it will melt really fast if you descend too quickly. But, I've used it for my lanyard with no problems.

Have you used it in a friction hitch and witnessed that alleged
melting?
Google doesn't take long to show that this cord has an aramid
(Technora) core--and aramids don't melt except at very high
temperatures. The polyester sheath might melt (which begs the
question as to the benefit of one component that doesn't!?).
But the cord's reported stiffness suggests that it might be not
so great (esp. in 8mm!) in a friction hitch.

(New England's own info claims melting at 1,200^F; max. working
temperature, however, will be well cooler.)

Reading the given information about various "prusik cords" at
www.wesspur.com/rope/bulk-prusik-cord.html
leads to some questions about how some of the quoted strengths
can be so different (100% Technora < 0.5 x 80% Technora),
and in other places where "average" and "minimum" strengths
are given, why there is a 10-15% variance (! --seems like a
lot, IMO)?!

Size Weight Tensile
lbs/100' g/m lbs kg
3mm 0.4 6.5 480 218
4mm 0.7 10.4 720 327
5mm 1.1 17.0 1,125 511
6mm 1.6 23.8 1,650 749
7mm 1.9 28.3 2,300 1,044
8mm 2.9 43.2 2,900 1,317
9mm 3.0 44.6 3,670 1,666

Sunlight/UV:
Very little degradation from sunlight. Can be used outside over long term if inspected regularly.

Chemicals:
Nylon will degrade with strong oxidizing agents, mineral acids, and 90% formic acid. May discolor when exposed to high levels of carbon dioxide.

Heat:
Nylon melts at 460°F with progressive strength loss above 300°F.

Dielectrics:
Good resistance to the passage of electrical current. However, dirt, surface contaminants, water entrapment, and the like can significantly affect dielectric properties. Extreme caution should be exercised any time a rope is in the proximity of live circuits.

Sheaves:
N/A

Working Loads:
No blanket safe working load (SWL) recommendations can be made for any line because SWL's must be calculated based on application, conditions of use, and potential danger to personnel among other considerations. It is recommended that the end user establish working loads and safety factors based on best practices established by the end user's industry; by professional judgment and personal experience; and after thorough assessment of all risks. The SWL is a guideline for the use of a rope in good condition for non-critical applications and should be reduced where life, limb, or valuable property is involved, or in cases of exceptional service such as shock loading, sustained loading, severe vibration, etc. The Cordage Institute specifies that the SWL of a rope shall be determined by dividing the Minimum Tensile Strength of the rope by a safety factor. The safety factor ranges from 5 to 12 for non-critical uses and is typically set at 15 for life lines.

Splicing Instructions:
Not Spliceable

i phoned and this is the cord i will take murph's idea, for today....
 
Yes, I saw their site: that is not "Tec(h)" cord,
but regular nylon kernmantle. The "Tech" is what got us
running: it denotes Technora.
