GY-708 Pistol Type Grease Gun Dual Port




Pistol Grip Grease Gun is the industry favorite for a reason. Engineered for durability and ease of use, this tool is specifically designed for lubricating machinery in tight, confined spaces where traditional two-handed grease guns simply won’t fit. With a powerful output and a “pinch-free” ergonomic design, it’s the perfect addition to any professional workshop or maintenance kit.
Key Features
- Top Port (Flexible Hose):The top port is usually oriented at an angle or positioned to allow a flexible whip hose to trail naturally.
- The Advantage: It allows you to snake the hose into cramped engine compartments, behind pulleys, or into deep recesses where a straight tool simply won’t fit.
- Best For: “Inaccessible” grease zerks that require you to hold the coupler on with one hand while pumping with the other.
- Front Port (Rigid Extension):The front port is located at the nose of the gun, providing a straight-line path for a steel pipe extension.
- The Advantage: It offers maximum stability. Because the extension is rigid, you can apply significant “push” pressure to keep the coupler seated on a stubborn or clogged fitting.
- Best For: Heavy machinery or open equipment where you have a clear line of sight and need to move quickly from one fitting to the next.
- One-Hand Operation: The super-strong pistol grip allows for effortless pumping with one hand, leaving your other hand free to steady the coupler.
- Pinch-Free Design: The ergonomic handle is specifically designed to prevent “pinching,” ensuring comfortable use even during repetitive tasks.
- Four-Way Loading: Maximum flexibility with support for Cartridge, Bulk, Suction, and Through Filler Pump loading.
- Variable Stroke Mechanism: Engineered for tight spaces; allows for effective greasing even when handle movement is restricted.
- Enhanced Control: Features a unique lock lever that secures the plunger rod at any position and a standard “T” handle for a sure grip.
- Precision Engineering: Built with a heavy-duty follower spring and rolled threads for fast, seamless reloading every time.
- Built for Durability: Includes a zinc-plated lever handle, an ergonomic rubber grip for comfort, and a back cap for easy barrel cleaning.
- Precision Components: Outfitted with both a Bulk Loader Valve and an Air Release Valve to ensure smooth, air-free operation.
- Volume Delivery: Delivers up to 0.50 gm per stroke (or 0.70 oz. per 40 strokes), allowing you to finish the job faster.
