Dear Sir, I am taking the liberty of sending you herewith particulars of our "EX-A-GUN" Forced Lubrication System, together with a sample of our standard Terminal, which we can supply upon wholesale terms at a low figure. You will note this terminal is screwed 1/8" gas, but we can supply same to any required rate of thread. We also supply this terminal with extensions from 1" to 2" in length for fitting in any inaccessible positions. You will note we fit a very strong Ball check spring and Ball check valve, to keep out dirt and water, which is only opened when the end connector of the Gun is applied to the terminal to force in the grease. Our Standard terminal (as per enclosed sample) is suitable for screwing into standard grease cups Prov. Pat. No. 12456. | ||
