NPT","description":"\u003cp\u003eAir tools and cylinders that were designed to run lubricated will run dry for a while and then stop running at all. Vanes glaze, seals dry out and tear, and a rotary tool that should have lasted five years is scrap in eighteen months. The L508 is the small mist lubricator that meters oil into the air stream so that does not happen.\u003c\/p\u003e\n\u003ch3\u003ePublished specification\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePort size: 1\/4 in.

The X9 suffix adds a manual twist drain. Check which one came off the machine before ordering, because the catalog column headings for this pair were printed in the opposite order in the older 0305-2 sheet and the confusion has followed the part around ever since. The ordering chart in both catalogs is consistent on one point: X9 is the drain.\u003c\/p\u003e\n\u003ch3\u003eSetting it\u003c\/h3\u003e\n\u003cp\u003eRun the tool at its normal duty and open the needle valve until you see one to three drops a minute in the sight dome. More is not better. Excess oil fogs the line, coats everything downstream, and ends up on the floor and on the work. Below about 0.5 SCFM the venturi does not develop enough signal to lift oil at all, which is why a lubricator on a line feeding one small intermittent cylinder often appears to do nothing.\u003c\/p\u003e\n\u003ch3\u003eDo not use it here\u003c\/h3\u003e\n\u003cp\u003eNever put a lubricator upstream of a dryer, a desiccant bed, a coalescing filter or anything with an air motor rated for oil free service. Oil ruins desiccant and plugs coalescing elements.\u003c\/p\u003e\n\u003cp\u003eParker Watts L508-02A miniature mist lubricator, 1\/4 in.
