Hi All,
I have a 25mm diameter 7 pin trailer plug that is very difficult to take out, even when the locking catch is released. Does anyone have any suggestions of what I can use that will make it easier to remove without breaking anything - last time almost broke my hand!
Cheers Grant

A bit of car cutter on the metal outside of the male portion should help.

Has anything damaged it.

They are better a bit tight rather than loose and falling out

Periodically spray the pins, both plug and socket, with WD40.

Try some fine wet and dry sandpaper to make sure everything is smooth. Then regular sprays of wd40 as suggested.

cheers If the plug on the car is metal, remove, dismantle and get to work with wet and dry on the inside.

Replace either the 7 pin plug or the 7 pin socket, or both.
They are not all that expensive.

I personally wouldn't use WD40 - an oil-based water-dispersant - on there as you will attract a lot of dust which will compound the problem. Use a DRY lubricant (I use Selleys DriLube) and spray on the OUTSIDE of the plug body, not on the contacts as teflon is a v.good insulator.
