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 ?

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 ?

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.
