Joining galvanised conduit

[Stringman_uk]

Hi all
I am running in some cctv on the outside of the house.
I intend to run the cable through 20/25mm metal conduit.
These come in 3m lengths, threaded both ends with a joiner.
Some of the runs need a T piece to raise a run to a higher camera position, but the length isless than 3m so I need to cut some conduit.
How do I join a cut piece of conduit to a threaded Box?

Thanks

Try conlock, I've not used it but it just bolts together with no threading required.

Conlok is an exciting labour saving range of quick fit conduit boxes and couplers designed to increase the speed of installation. Standard conduit tube is still used with the usual accessories replaced by Conlok boxes, couplings and adaptors. The Conlok

Craplock more like.
Joints which are 'fixed' together by a single grub screw, not waterproof, when used outside the conduit will fill with water, the screw points will gouge into the galvanised coating to ensure corrosion.
It's overpriced junk which was created to deskill the industry so that ham-fisted imported labourer types who will work for less than minimum wage can be let loose on 'installing' electrical conduit.

Oh, that good is it lol.

Possibly true, but only a small proportion of conduit is used outside. They're fine indoors, and very useful for us very occasional users who can't justify the cost of kit needed to make 'proper' joints.

I presume you voted for Reform, if their were elections in your area

A grub screw securing a sleeve on a shaft has been effective for decades in many different situations- so that argument is a pile of junk

Neither are threaded joints - so that argument is a pile of junk

threading a tube ensures corrosion- so that argument is a pile of junk

It's a system which has been in use for many decades, well before minimum wage rules- so that argument is a pile of junk

Hmmm it appears your whole reply is a pile of junk.

I didnt want to start WW3 lol, just thought it would be nice and easy for a diyer without a pipe vice or stocks and dies..

I have used a number of times and find it to be very effective in the right situation. It means I can go to a job, requiring a small amount of conduit work, with a regular set of hand tools and complete the works without having to lug heavy benders/vice and dies. However despite my reply to Johns irreverent comment I wouldn't suggest using conlock at the bottom of a vertical tube as the water will run down the outside of the tube and enter the fitting.

In this instance the only one starting WW3 followed your valid suggestion. There are ways to discuss things but those who set themselves up as some sort of perfectionist are never able to and equally never realise they are unable to.

Why metal conduit, plastic can be as effective, but cheaper, quicker, and considerably easier, plus no risk of it rusting.

Certainly not. Reform are extremist grifters who serve only themselves.

If you do go for plastic, use expansion couplers, if you dont it will warp in the sun then it will look carp.

I know other countries use different rules, including free air joints on bends. Why CCTV needs conduit, not sure? In the main, steel conduit is used to stop physical damage. It was a massive argument where I used to work, SWA or steel conduit, I went for SWA. Although I have seen problems with that, with hydrochloric acid being forced down the cable, and we had to put in cable joints to stop it, so horses for courses, one has to work out the approbate method.

As to if sealed, it would depend on if sealant used, and as to rust, depends on if some stuff used on threads. The vice, dies, and bender, were a good reason not to use steel conduit, but why not plastic conduit? There are long joiners where non setting glue can be used, and the plastic version can be waterproof, where it is harder to keep steel waterproof, but steel is better at being crushproof, so what are your aims?

As I wrote, you're dead right - which is the very reason I have occasionally used them.

Kind Regards, John

I can fairly easily put a spade through SWA, but wouldn't stand a chance with stell conduit - so if it's 'mechanical protection' one wants .....
