Joy lubricators were pressure tested to destruction and required internal pressures exceeding 1200 psi before cracks began to appear in castings.  Even at extreme pressure the cracks which appear simply release internal pressure without exploding the lubricator. The safety filler cap warns when opening the Lubricator under pressure.  The Joy Lubricator has been thoroughly tested and found to be a safe pressure vessel.

Recommended for use with quality rock drill oil or triple zero (000) rock drill grease.
