Grease Guns and Grease Pumps

Professional Grease Guns & Pneumatic Grease Pumps

Best Buy Auto Equipment offers a comprehensive selection of professional-grade grease guns and grease pumps designed for automotive service, heavy equipment maintenance, and industrial lubrication applications. Our inventory includes manual pistol-grip guns, lever-action models, pneumatic grease guns, air-operated pumps, and electric corded systems to meet the demands of professional technicians and fleet maintenance operations.

Pistol-Grip Grease Guns: These compact, one-handed operation tools are ideal for general automotive lubrication and hard-to-reach grease fittings. Models typically accommodate 14-16 oz. cartridges or bulk loading, with output pressures ranging up to 7,500 PSI depending on the model. Pistol-grip designs offer excellent maneuverability in tight engine compartments and undercarriage access points.

Lever-Action Grease Guns: Professional-grade lever guns provide variable stroke capability—short strokes for high pressure applications and long strokes for high-volume dispensing. These heavy-duty models generally feature three-way loading options (cartridge, bulk, or suction) and can develop pressures up to 10,000 PSI. The longer barrel length, typically around 21-22 inches, allows for greater grease capacity and extended reach.

Pneumatic Grease Guns: Air-powered grease guns eliminate manual pumping effort and provide consistent, continuous operation for high-volume lubrication tasks. These fully automatic tools typically operate within an air pressure range of 40-150 PSI and can generate grease pressures up to 6,000 PSI or higher. Variable-speed triggers offer precise flow control, making pneumatic guns ideal for fleet maintenance and production environments.

Electric Grease Guns: Corded electric models deliver high torque and consistent performance without requiring compressed air. These professional tools generally feature multi-speed transmissions, variable speed triggers, and patented stroke counters for measurable grease output—essential for preventive maintenance programs and equipment warranty compliance.

Air-Operated Grease Pumps: For shop operations requiring bulk grease dispensing, air-operated drum pumps provide high-volume delivery directly from 120 lb. or larger grease drums. These stationary systems can dispense 45 ounces or more per minute and typically include roll-around bases for mobility within the service bay.

Loading Options: Modern grease guns typically offer two-way or three-way loading capabilities. Cartridge loading provides clean, convenient operation with pre-packaged grease. Bulk loading allows shops to use more economical drum grease. Suction loading enables filling directly from bulk containers. Consider your shop's grease purchasing and storage practices when selecting a loading method.

Pressure Output: Different lubrication points require varying pressure levels. Standard automotive fittings generally work well with guns producing 3,600-7,500 PSI, while heavy equipment and industrial applications may require higher pressures. Ensure your selected gun provides adequate pressure for your specific equipment without exceeding fitting or component ratings.

Hoses and Extensions: Grease guns are commonly equipped with rigid pipes (typically 3.5-5 inches), flexible whip hoses (generally 18-30 inches), or combinations of both. Flexible hoses provide better access to awkward angles, while rigid pipes offer more control for precise fitting engagement. High-pressure hoses with dual spring guards help prevent kinking and extend service life.

Air Bleeders and Priming: Quality grease guns incorporate air bleeder valves, quick-vent features, or combination filler nipple/bleeder designs to purge trapped air from the system. Proper priming ensures consistent grease flow and prevents air pockets that can cause incomplete lubrication or fitting damage.

Construction Quality: Professional-grade guns feature rugged cast pump heads, heavy follower springs for positive priming, and durable follower seals designed to handle both cartridge and bulk grease. These construction elements contribute to long-term reliability in demanding shop environments.

Important: Specifications vary by model. Always check individual product listings and manufacturer documentation for exact details regarding pressure ratings, capacity, dimensions, and compatibility before purchase.
