Professional Dual-Piston Grease Gun, 500ml Capacity

Brief Overview

This is a rugged, purpose-built transfer gun engineered specifically for gear oils and fluid management in automotive drivetrain maintenance. The dual-piston design delivers consistent pressure for extracting and injecting fluids into gear boxes, transfer cases, and differentials—critical tasks in professional service shops and fleet maintenance operations. If you're stocking hand-operated lubrication tools, pair this with complementary manual grease dispensers or consider upgrading your shop with pneumatic grease delivery systems for higher-volume operations.

Key Features

• Dual-Piston Mechanism: Engineered for consistent, controlled fluid delivery in both directions (intake and output)
• Deluxe Lip Seal: Maximizes suction capability, reducing air leakage and ensuring reliable priming
• Extended Suction Hose: 300mm vinyl hose for accessing deep reservoir fill points and distant fluid sources
• Non-Slip Operating Surface: Textured grip and ribbed rubber handle provide secure purchase under wet or oily conditions
• Metal Construction: Zinc-plated steel components resist corrosion from mineral oils and industrial fluids
• Professional Lever Linkage: Riveted dual-piston guide rods and sturdy lever assembly built for repeated daily use
• 500ml Working Capacity: Sized for single-service fluid transfers without constant refilling

Ideal Applications

• Gear box fluid extraction and refilling (manual transmissions, automatic housings)
• Transfer case servicing (4WD and AWD vehicles)
• Differential fluid management (front and rear axle units)
• Non-corrosive liquid transfer (gear oils, ATF, synthetic fluids)
• Workshops and fleet maintenance where controlled fluid handling is essential

Business Advantages for Resellers

• High Turnover Item: Essential tool in any professional service shop; mechanics need reliable fluid transfer equipment
• Durable Build: Dual-piston design and riveted construction ensure long service life, reducing warranty claims
• Competitive Positioning: Fills a specific niche between basic grease guns and expensive pneumatic systems—strong margin potential
• Bulk Order Friendly: Lightweight, compact design makes shipping economical for case quantities
• Upsell Opportunity: Pair with adapter kits and complementary manual or pneumatic systems for larger shop orders

Why This Gun Matters to Your Customers

Professionals working on gear boxes and transfer cases face a critical challenge: controlled, mess-free fluid extraction and refilling in confined spaces. This dual-piston gun eliminates the guesswork. The extended 300mm suction hose reaches deep into reservoirs without removing overflow plugs, and the lip seal prevents the air pockets that undermine cheaper single-piston designs. The textured, non-slip surface ensures confident handling when working beneath vehicles or in damp environments.

At 500ml capacity, it's the right size for precision work—large enough to reduce refilling frequency on most service calls, yet compact enough for technicians to maneuver in tight engine bays or suspension mounting areas.

Recommendation for Shop Orders

Stock this alongside manual grease dispensing tools for comprehensive drivetrain service coverage. For shops handling high fluid volumes, consider also offering air-powered alternatives to your larger fleet customers—the hand gun serves as an excellent entry-level option and backup for pneumatic systems.

Professional-grade durability. Straightforward design. Reliable performance. This is the fluid transfer gun that pays for itself on the first transmission service.
