Flex conduit into plastic box?

[23vc]

Apols if this is the wrong forum section but I know there’s plenty here that’ll know this. I want to terminate some of that black flex 20mm conduit into an IP65 box on the wall (in my case for cat7 Ethernet cable), any idea if you can get a gland/connector for this? I’d rather make a proper connection than just butt the conduit up to the underside of the box and silicone it.
Ta very much for any words of wisdom

If you buy a contractors pack of flex conduit the glands come with it, they are also available as a separate item, Toolstation have them

Yes, you can get correct glands to make a good connection.

Thanks, I just got the coil, no fittings. Any idea what they’re called? Think I’m searching for the wrong thing

Brilliant, thanks. Let myself down today with my product searching.

Be aware that unlike most rigid conduit, flexible conduit comes in various types and is not standardised across different manufactures. Unless you buy the specific glands for your conduit there is no guarantee of a good fit

They are no good to use externally ….they will let water in ….the above may be better or the ones from Screwfix

That was just an example to show '23vc' what they needed. I did say other suppliers and different colours are available. He/she will need to decide on the best ones suited for them.

Note that the basic flexible conduit and fittings are NOT waterproof. So if you are going to use them in an area where water may be present you need to think very carefully about drainage.

Even if you buy a system that is nominally waterproof, it probablly still pays to think about what happens if/when the waterproofing fails.

I have used these https://www.screwfix.com/p/tower-male-conduit-adaptors-20mm-black-2-pack/64512 successfully. Using plenty of solvent weld adhesive to seal the conduit into the adaptor to water proof the join.

Thanks, Yes that does look better as it’s IP44 at least

Thanks Bernard, does the flex stuff (obviously depending on the brand) fit inside that then?

 

[23vc]

Btw, the only reason I’m doing this at all, is to bring a cat7 cable out of the house wall and down into the flex conduit and try to stop water getting into the conduit. I could do a “hockey stick” jobbie where the conduit gets bent back down to stop water ingress, but I’m
Not sure it’ll withstand that in the long term.

fit inside that then

Yes it does fit inside,

There is a slight variation in the 20mm outside diameter of the flexible depending on the brand.
