Heavy-duty manual hand pump for transferring oil, transmission fluid (ATF), gear oil, hydraulic fluid, brake fluid, coolant, and other automotive lubricants directly from gallon and wide-mouth quart bottles. Each stroke dispenses approximately 1 fluid ounce (30ml) for precise control. No batteries, no electric motor, no maintenance — simple piston design that works every time.
4 cap adapter sizes included: 38mm / 1.50in, 40mm / 1.57in, 43mm / 1.69in, and 50mm / 1.97in. Fits standard 1-gallon automotive fluid bottles from Mobil 1, Castrol, Valvoline, Pennzoil, Royal Purple, Amsoil, Liqui Moly, Motul, Red Line, and most major brands. Also fits select wide-mouth quart bottles — measure your bottle opening before use.
Important: designed for gallon bottles and wide-mouth quart bottles only. Does NOT fit standard narrow-mouth quart bottles (typical 32oz quart with small spout). Always measure your bottle opening diameter and compare to included adapter sizes (38mm, 40mm, 43mm, 50mm) before purchase.
Includes short and long flexible extension tubes for reaching deep transmissions, differentials, and hard-to-access reservoirs without spills. Perfect for filling automatic transmissions through the dipstick tube, refilling manual transmission and differential gear oil through fill plug holes, transferring engine oil during DIY oil changes, refilling power steering fluid, hydraulic systems, lawnmowers, ATVs, snowblowers, motorcycles, and marine engines.
Construction: durable polyethylene pump body resistant to all common automotive fluids. Compatible with engine oil (conventional and synthetic), ATF (Dexron, Mercon, CVT, DSG), gear oil (75W-90, 80W-90, 75W-140), brake fluid (DOT 3, 4, 5, 5.1), power steering fluid, coolant, antifreeze, washer fluid, and hydraulic fluid. One pump replaces dozens of dedicated fluid funnels and squeeze bottles.
