Greenlee 50282379 Dark Cutting/Threading Oil - 1 Qt

Greenlee's 50282379 is the dark type. Dark threading oils are the heavier, higher-lubricity choice for steel pipe threading, where the cut is aggressive and you want maximum film strength on the die. Clear oils are the ones typically chosen where staining matters or where the work is on stainless and lighter metals. If your job is black iron or galvanized conduit and pipe threading, dark is the normal pick.

It's a dark threading and cutting oil for pipe threading and metal cutting work. Greenlee describes it as a premium high lubricity oil that makes cutting easier and extends tool life, so it's what you run on threading dies, pipe threaders, and cutting tools to keep heat and galling down on the cutter.

One quart, which Greenlee also states as 0.900 L. That's the small can size most electricians and plumbers keep on the truck for hand threaders and touch-up work rather than for filling a powered threading machine's reservoir, which takes gallons.

Yes. Country of origin on the 50282379 quart is the US. That matters if you're buying under a Buy American or domestic-preference requirement on a government, education, or healthcare contract.

Manufacturer part number is 50282379, UPC 783310282372. That's the identifier to quote when you're matching an existing standing order or adding it to a Greenlee threader kit.
