Bulkhead fitting - help needed

[Berin]

Hi chaps. I've fitted a peli case to my bike that I want to use to house my Kenwood radio and Ipod thingy.

I need to drill a hole in the case to thread the 7-pin fitting through - but how can I seal the hole around the cable? The 7 pin socket is about 15mm, the cable only about 2-3mm. Most grommets I've seen seem to work on the principle that the cable you're threading through is constant diameter.

Any ideas?

Round top stuffing glands.

Linky

use them at work for passing network cables through steel panels. The holes sufficiently large to let a CAT5 or 6 plug through but will then clamp down small enough to secure the cable. Of course real IT people leave a ragged hole with razor sharp edges and simply poke the cable through

Thanks! How do these work? Do I buy some with to fit the diameter of the 7-pin socket so that I can push the socket through and then it somehow closes down to the size of the cable?

Yep. 20mm hole through your case and then pass the plug through the gland. If the plugs too big you may need a 25mm gland but that may not pull down sufficiently small for the cable.

I've ordered a selection. I knew someone would know

If you want it water proof, get a cable gland for marin euse. More expenisve, but creates a watertight seal (the hole in the middle has an expandable rubber seal in it, like a rubber olive if you like). Same principle as the placky one above, just more substantial and watertight. Used for things like Radar/VHF cables to run through the deck/wheelhouse roof or similar.

No links, just type cable gland in and you'll get dozens.

Good tip - there are waterproof glands available that are split to allow for a connector to push through which then seal on the cable, and also to allow multiple cables through the same gland.
