Grease nipples, also known as grease fittings or zerks, are vital for machine lubrication. Grease nipples are metal fittings used to feed lubricants into a bearing. A grease gun is attached to a grease nipple and then the lubricant is fed through under pressure. We have different sizes of grease fittings including metric grease nipples and imperial grease nipples. We have a box of 80 metric grease fittings, with both straight and angle grease fittings. We also have a needle nose dispenser which is used for dispensing a thin line of grease. It’s ideal for hard-to-reach places. We also stock button head couplers. Button head couplers are quite sturdy and have a high flow rate, so a large amount of grease can pass through them. This makes them ideal for contractor’s equipment or heavy machinery.
