cooling system T-piece options

[jmaz]

For my 310 Encore build, I'm considering replacing the supplied, blue-plastic T-piece that connects the engine, modine and expansion tank with the one recommended here (Gates 19mm T-piece, part # 28635) (https://caterham420detailedbuildblog.co.uk/2019/12/19/engine-plumbing-part-1/) or a stainless steel version.  The Gates one (nylon-reinforced plastic) is designed specifically for auto use and might be more durable overall.  Any suggestions or experience re. this t-piece would be welcome.

I consider those blue fittings suitable only for PCV/vent applications

or your lawn sprinkler

Hi @jmaz.  I have a few of these that I would be willing to send you for free, but the complicated postal system these days is too much to contend with. You don't mention the o.d. of the fittings required, but go to your local big box hardware store and look for 'Pex' fittings.  They should be made of brass (sometimes chrome over brass?) and normally come manufactured for 1/2" pex pipe or 3/4" pipe.  You may require metric size for your car, and if so, some Italian manufactured pex fitting may be available, but not sure.  Here in Canada, although mostly metric, we rely on Imperial fitting sizes along with many other construction items also in Imperial measure.  Cheers W.

Thanks for that kind offer and suggestion re. the pex version.   I'd gotten another recommendation for the Gates 28635 T-piece (from Josh Robbins at Rocky Mountain Caterham), so I've ordered one for around $8.00 from Amazon.  It seems like one of those strange ways in which Caterham does things, where they could easily and cheaply upgrade a part but choose not to.
