Drip feed oilers are single point lubricators designed to be mounted directly on lubrication points. They dispense oil by gravity from transparent reservoirs through a needle valve. The needle valve features a toggle pin, allowing the operator to manually switch the oil flow on or off. This type of oiler is ideal where regulation of oil feed is necessary. Drip feed oilers are recommended in applications requiring a visible and controlled oil supply.Product Name: Drip Feed Oiler Capacity: 50cm / 50mL Material: Plexiglass, Aluminum Thread Diameter: 14mm Body Size: 44 x 45mm / 1.7" x 1.8" (D * H) Total Height: 113mm / 4.5" Color: Clear, Silver Tone Weight: 107g Package Contents: 1 x Drip Feed Oiler Note: Light and display differences may cause slight variations in color between the image and the actual item.
