Copex

[m4tty]

Hi,

Any of you guys use copex alot?

I've got to do a job next week involving it and was looking for a heads up on how to do the glands etc

Where is it normally used?

Thanks for any information

The glands take seconds to attach, after you have done one you will probably (costs permitting) use it a lot more. Just slip the collar on and screw the gland down then lock it in place with the lock nut.

I don't use Kopex that much tbh but I do use flexible conduit a lot!

It depends mate on what system you use.

I tend to use the IP65/66/67 rated all plastic systems as where I use it there is little chance of mechanical damage.

Just cut it square and clean (no burrs) fit into the gland and tighten, though most of the ones I use are push fit!

What is the application mate?

Kopex is a brand like Hoover.

DO NOT rely on the metallic flexy for your earthing at all EVER!

Very true I always earth each end but always put a cpc through. There are many differing types of flexible conduit as Sidewinder says.

I'm more likely to have a pack of this and glands in the van than a reel of T&E!

Kopex , M4tty , is mainly for flexible connections to machines and motors . There are various types , standard, oil proof etc. As Manator says , glands just push oo and use a plastic olive (Same as a plumbing compression fitting )

Its a flexible tube formed by a spiral of metal covered in PVC. Can't use the spiral as an earth conductor.

I prefer Adaptorflex but its all much the same stuff TBH.

Ive used the PVC stuff with a split adaptor that just clips over in the past

As Manator said, it's dead easy to use Matty . I never used to use it that much myself but then I recently became involved in a big contract wiring up external oil fired central heating boilers. I put the external isolators on the adjacent wall and used it to go from the isolator to the back of each boiler which stood about 12 inches from the external wall of the house.

you cut it at 60

 

[Sidewinder]

Not the stuff I use

 

[Manator]

+1 ^ Looks a bit flimsy to me, and not suitable for what I use it for. I have made up lengths in the workshop, subject to on site surveys of course, and most cuts are made on a bench saw for speed, never had a problem with them being cut square, in fact the collars fit better.

 

[Lee321]

flimsy! that is the original Kopex as in where the trade name came from! its the best stuff you can buy top of the market

tough as old boots and will be found in most specifications standard and specific

 

[Manator]

Flimsy was an observation it still looks thinner than the stuff I use, and from the looks of it Sidewinder suggests the same.

 

[Lee321]

there are different types yes but spec for spec Kopex is the daddy expensive but the best/industry standard

offers upto ip54 intended for regular movement and offer good mechanical impact protection (hard pushed to crush it with jumping onit with both feet)

you'd not need go up a protection spec (thicker wall) unless more ip needed or heavier impacts expected even then that impact should be removed as it would be significant
