I needed to replace the swan neck since a pressure test revealed leakage from a small dent in the brass seal

I was going to replace with a standard item from Adam but time pressure meant going a different route:



The ears holding the cap are much stronger

The seal area is much larger (about 4 times) so a reseal will probably work

The QH FC57 cap fits well

There is only 1 joint at the filler

The overflow hose fits fine (just trimmed the rubber hose)

downsides ?

Only available in 32 or 38mm but silicone reducers are available and 35mm rubber coolant hose will fit the large size

You have to cut the swan neck

Please do not let your pet hamster, rabbit, gerbil etc cut the pipes: use one of these

I've just done that too - my replacement S/S jobbie from a well known supplier had a brass seal which was totally useless at keeping the pressure despite the many adjustment I tried. Needless to say I'm not into pretty upgrades if they don't the job they were supposed to do in the first place...

Looks tidy. I hope the overflow stub has a decent weld around the inside because there's a gap you could sail a yacht through there...

I have the same one on my car but there could be an issue. The cap should be of the plain variety with the pressure cap on the header tank. The over flow there is not fully welded and will leak water if under pressure. I welded mine up.

Sorry it's not a great picture.

I like your cutter do you have a link on where you can buy them.

It's a plumbing pipe cutter left over from bathroom refits

About £20 but here's a cheaper version:
