The great majority of plants have hard to reach lubrication sites. The LubeLine Refill Kit allows refilling from distances up to 10 feet, and will fit all grease units. The LubeLine Refill Kit comes complete with all of the required fittings and 10 feet of high pressure tube. Remember, this product is specifically designed to refill a LubeSite unit, not replace it. LubeLine units should be prefilled prior to hook-up to the LubeSite unit. Be certain the LubeLine Refill Kit is free of all air bubbles.
