The extended grease tip allows access to recessed mechanical parts, which helps locate the grease nipple in blind spots. Easy to use in narrow areas. The smooth retraction mechanism allows one-handed operation. Once the grease connector is locked onto the nipple, it will remain open, freeing both hands to operate the grease tool. Grease tooltip is made of high-quality stainless steel, which is strong and durable without breakage, leakage, warping, or typical wear and tear.
