Quote from: cnr6400These items were discussed several years ago on another forum. Most people said they made their own or had a friend with a lathe make some. But I recall there was a New York City firm mentioned that specialized in repairing coffee and espresso machines that had them. Might be worth a google search using "espresso pipe nipples soldered" or something like that. Good luck! 

(If you cant find any, I do know there are a few places in UK you can get them, original purpose for old car repairs. MG used them on some cars. But shipping may be costly from UK)

Thanks for this, yes, a lot of suppliers in the UK, may have to pay shipping unfortunately. I will take a look at coffee machine parts though - thank-you!

Hi All,

Sorry if this is in the wrong forum. I’m looking for a supplier of 1/4” union cones (solder nipples) in the USA. PM Research has sizes but not 1/4”. I’ve searched around a lot and can’t find any - maybe named differently. I could make them but would prefer to buy if possible.

Appreciate any help…

Hi All,

So I used a 1/6" ID, piton o-ring and it has reduced the leakage a lot. I plan on stripping the engine for final fishing and will clean/polish the valve rod to see if I can get a better seal. Right now I'm pretty happy with the engine. I've attached a video of the engine running. Hope you like.

Thanks for all your help!!!!

I bought some 1/6" ID piton o-rings that are 0.103" cross section (did of rubber).
I will try these today and post the results.

I'm sorry - yes, the valve rod is 3/32 (a typo)
