Who makes a displacement lubricator threaded 3/16-40 ?

Who makes displacement lubricators for stationary steam engines ? I require the inlet pipe to be threaded 3/16-40.

PMR

I should have said ''…other than PMR''. Surely somebody else must make them ?

[Brian JohnParticipant @brianjohn93961]

The PMR lubricators have one inlet/outlet pipe which is to be connected to a T junction. I have been using these for a few years but the postage costs from the US are getting prohibitive. I found these displacement lubricators from China but they have have two pipes. How are they connected ie. which is the inlet and which is the outlet ?

The one which you linked to looks to be a straight through type – steam in one end and lubricated steam out of the other. If they're made like the one I saw, either end can be steam in.

Why not make one Brian? You've got the skills now.

Brian, if you want to make a disp. lubricator then possibly this article from 10 years ago may be useful … if you find MODEL ENGINEER magazine for 31 august 2007 there is a lubricator shown which is threaded 3/16 x 40 … I think the issue was 4307, volume 199 … please be aware there was a printing error made by some unknown gremlins in the computer … at the top of the lubricator there is a cross-hole to be drilled … obviously it cannot be 0. 21 inches as shown … it should have been 0. 021 inches diameter … the actual page number is 276 and the drawing is in the bottom right-hand corner.

P.S. I have always used this type of lubricator on non-superheated steam … hope this is of some use.

I will lookinto making my own and see what I can find in the way of plans.

Reagrds the Chinese lubricator : why is one side threaded and the other side is not ?

[Gordon TarlingParticipant @gordontarling37126]

Brian, I think the plain side is to allow you to solder it in to whatever it's feeding. You could also put a union nut and olive on it.
