PM Research Model Steam Boiler Displacement Lubricator (Lub-1 & lub-2)

Steam Displacement Lubricator

For cylinders from 1/2″ up to 2″ bore.

Please choose your lubricator below.

Two options available:

LUB-1: 5/8″ diameter brass body, approximately 2-5/8″ long, with 1/4-40 threads.

LUB-2: 5/8″ diameter brass body, approximately 2″ long, 3/16-40 threads.

This lubricator should be attached to the steam chest, or fitted to the steam line close to the engine by a tee. Opening a needle valve lets steam pass into the lubricator. Steam condenses in the lubricator and sinks to the bottom. Oil is displaced by the water and passes into the steam line, lubricating the engine.

Lubricator may be refilled by closing the needle valve, opening the drain valve to remove water, and removing the cover plug to refill with oil.
