Part number mix up.

Today I topped up the water in the 110. I checked the rad too and it was
nicely full. Though in reinserting the brass plug in the top of the rad what
ever seal was there began to disintergrate.

Went up to Landranger and they sold me  an O ring

ERR4685

It's too big!

I've just had a butchers on EPC and it suggestes

NTC5171

Do these part numbers equate to size in any way?

how frustrating!  (Insert rant of choice here).

Would PTF tape do the trick as a get me going or is it a none starter? It's
got to be sorted properly but the 110 is in demand at the mo.

My 110 is a 1990 TD CSW.

Not sure exactly what you have there but the RRC has one plug with an O ring in it and another with a flat rubber washer, obvioulsy the o ring needs to be constrained otherwise it ooses out.

I fitted some X-Plugs to mine and found that a simple cardboard washer did the trick against the flat surface of the X-plug.

Failing that a bicylce inner tube and some scissors or as you suggest PTFE tape, it certainly will withstand the temperature of the rad and is pretty much designed for the purpose, provided you get the right amount in there.

Failing that any plumbers merchant should be able to sort you out with an O ring of size

Cheers chaps,

I wondered in to LR today with the brass plug which cuased them to scratch their heads as they only supply plastic.... which had a groove in for the O ring.

One plastic bung later and I'm back on the road.

Why is it always the simple things!  :roll:

Brass plug is found on top of a V8 EFi for the heater pipe filler, to prevent air locks.
