I know the Model IC engine guys swear by sheet teflon for head gaskets.
I have'nt tried it yet, but it may be worth a try...It will take the heat to 500 F. My teflon piston rings work great!...but use a float lap joint to seal them.

My engine uses standard automotive gasket material on the heads and has so far worked just fine. Viton O rings work very well on my engine for static seals around the valve sleeves and the receiver plumbing

dont bother with gaskets use high temperature gasket 'goo' available in presurised cans from automotive spares outlets. A bit like silicone sealant except you dont need a gun. keep the cap on and it will always work next time you want it without having to clear the nozzle. works for steam, hot water, oil and funnel/flue joints. Good for 230 deg.C. Only thing it does not like is petrol but perhaps that will not be a problem in most steam plants. Brand name of the one we use on all our locos/ marine steram plants is Granville Oil and Chemical Ltd Rotheram Yorks Tel. 01709 891121

I started using "never-seeze" with automobile gaskets-works well for me and I don't destroy the gasket when I have to take it apart! It works well with the pipe fittings as well [I always worry about breaking something when I knock it apart in winter!] -Remember just tight enough not to leak-someone has to get it apart later and sometimes not with the right tools!

Hi Folks

Just a thought from a non-engineer. A friend has just sent me a catalogue of gaskets aimed primarily at the Petro-Chem industry. They all seem to be very happy with steam at quite high temperatures, so it might be worth a look. The firm operates worldwide, and to my great surprise the UK base is just down the road from here:

James Walker & Co Ltd
Customer Support Centre
1 Millennium Gate, Westmere Drive
Crewe, Cheshire CW1 6AY, UK
Tel: +44 (0)1270 536000
Fax: +44 (0)1270 536100

They might cut to your pattern or send you some material by the meter.

For steam gaskets, I've used either high temperature silicone "form-a-gasket" automotive material or industrial steam gasket material from mcmaster-carr:

For frequently removed components, the sheet gasket is much less annoying; the silicone rubber is easier to make .

My safety is set at 180 psi and we don't run superheat.
