Ingco 400cc Industrial Dual-Piston Heavy-Duty Grease Gun – High-Volume 6000 PSI Professional Manual Lever Grease Gun with 12-Inch Flexible Hose & Metal Bend Spout (GRG015002)

Neglecting regular lubrication on heavy machinery joints, vehicle bearings, and drive shafts causes catastrophic friction wear, high operating temperatures, and eventual mechanical seizure. Standard grease guns often suffer from low pressure, leaky seals, and painful priming issues that turn a critical maintenance task into a messy, inefficient chore. The Ingco GRG015002 400cc Industrial Dual-Piston Heavy-Duty Grease Gun is an engineered, high-pressure lubrication solution built to keep your equipment running smoothly. Outfitted with an advanced dual-piston pump assembly, this manual lever gun delivers twice the grease volume per stroke compared to single-piston alternatives, making it fast and effortless to purge dirty bearings and pack clean grease exactly where it is needed.

The extreme structural integrity and sealing power of this grease gun stem from its heavy-duty 1.2mm cold-drawn steel tube and rugged cast-aluminum head assembly. Engineered to withstand a massive working pressure of 3,600 PSI and a burst pressure rating of up to 6,000 PSI, the GRG015002 easily breaks through clogged or seized grease fittings. It features a highly versatile dual-loading system, accepting standard 14oz grease cartridges or 400cc bulk suction fills. Packed with a durable 12-inch high-pressure flexible nylon hose and a classic metallic bend spout, this premium kit gives you the physical reach and physical leverage to service recessed joints on automotive chassis, agricultural tractors, and industrial factory floor machinery.

Key Features

• High-Volume Dual-Piston Engine – Double-piston pump geometry delivers a minimum of 3oz of grease per 40 strokes, cutting your maintenance prep time in half.

• Heavy-Gauge 1.2mm Steel Tube – Constructed with a thick, cold-drawn 1.2mm steel cylinder barrel to resist dropping damage and structural warping in harsh workshops.

• Exceptional 6,000 PSI Limit – Operates smoothly at 3,600 PSI working pressure, peaking at a 6,000 PSI burst ceiling to push through the most stubborn, dirt-blocked grease nipples.

• Dual-Method Cartridge & Bulk Loading – Highly adaptable design supports quick 14oz cartridge loading or direct 400cc bulk suction container filling.

• Two-Piece Delivery Accessory Kit – Includes a 12-inch heavy-duty flexible nylon hose for awkward angles and a rigid metallic bend spout for direct, high-leverage application.

• Ergonomic Leverage Handle – Features a non-slip, comfort-molded lever handle that maximizes physical squeezing force while preventing hand strain over long shifts.
