Office of Steam Forum for Model & Toy Steam Gas & Hot Air Engines

Most shop compressors and air manifolds at shows require a 1/4 NPT.

You will want a precision regulator large enough to run a good sized steam engine. I will post pictures of  these components tomorrow or Friday.

Some quick disconnect fittings and 1/4" hose barbs of 1/4 & 1/8 NPT .

Harbor Freight has  good selection of reasonably priced compressors including some that are compact and very quiet. I will add a picture of this as time allows.

edit:  you can view some here.

I mostly use the 2 gallon Fortress compressors.

I also have A 30 gallon rather loud one in the garage.

Thanks for this info!

Currently I’ve been using the home made fittings as seen in the photos below. I use silicone tubing with a nylon connector and then a small zip tie to secure it. The other end is an 1/4” Compression Union to 1/8 Pipe threads with a 1/8 barb.  Secured in with the smallest hose possible that my hardware store supplies and a zip tie.  I can interchange almost any engine this way with ease, albeit it can run under 15-20 psi that the Jensen boiler puts out.  It works great!  👍🏻 I will see to getting the right fittings and an air compressor soon.
