Standard immersion heater 2-1/4 inch BSP thread.

The male part of the fitting that goes through the cylinder has a 2-1/4 inch BSP thread, this measures about 65.7mm diameter,

2kw is the most i would like to go , i put on a 2kw fan heater in my icebox connie the other day for only an hour and the lead and plug got rather hot , cable went spaghetti like .

My immersion is getting fitted tomorrow.
Could anyone tell me with the mechanical flange the bit with the nipple bits on it goes inside the tank and then pull that through the drilled hole and screw the other bit to it.
Does the gasket that came with the flange go on the bit on the outside of the tank.
The immersion heater itself just has a rubber o ring on it.
Is it wise to use Pte tape and a sealant.

Thanks for any advise

Washer on the inside, i bought some good quality silicone and let it go off for12-24 hours.

Never leaked.

This is why it asked the question if the cardboard gasket goes on the inside the little nipples on the flange will not be able to grip on the plastic of the tank so you can tighten without holding from the inside.

[paul alan]

Silicone will do it just fine, without the gasket.

[Darren H]

Did you use silicon on both sides

[DeLuce]

Belt and braces. I would. No harm if you do either 👍🏼

[Slacky]

A belt and a set of braces?

Surely you need silicone to seal it, regardless of it slipping below the waistline?

Nipple part fits from the inside, push the threads through the tank wall and screw the other part to it from the outside. I have never used any sealant with the flange but PTFE the actual element threads. No washer is fitted to the nipple side. You can file a flat on the side of the nipples to aid "bite" into the tank wall if you struggle to get it to grip.👍
