Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Grease Application: Delivers high-pressure (4,500 PSI) lubrication for heavy-duty machinery and equipment, ensuring optimal performance in demanding environments.
  • Precision Delivery: Equipped with interchangeable nozzles (straight and bent) for targeted grease application in tight spaces or hard-to-reach areas.
  • Ergonomic Design: Steel lever grip provides comfort and control during prolonged use, reducing user fatigue.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a stainless steel and steel body, ensure long-lasting durability in harsh industrial environments*. The corrosion-resistant construction outperforms traditional plastic-based grease guns prone to wear and deformation.

  • 2. Ergonomic Interactive Design

    • With an ergonomic steel lever grip, reduce hand fatigue during prolonged use*. The reinforced steel handle provides superior comfort compared to non-ergonomic designs, ideal for repetitive lubrication tasks.

  • 3. High-Pressure Performance

    • With 4,500 PSI working pressure, deliver powerful grease application for heavy machinery*. This exceeds standard consumer-grade grease guns (typically 2,000–3,000 PSI), ensuring efficient lubrication in demanding industrial settings.

  • 4. Multi-Scenario Adaptability

    • With multi-nozzle adaptability (straight/bent), access tight spaces and diverse lubrication needs efficiently*. The versatile nozzle system and professional-grade build cater to both precision tasks and commercial-scale operations.

  • 5. Eco-Friendly Compliance

    • With EC1907/2006 certification, meet stringent EU eco-friendly standards for professional environments*. This ensures safe disposal and compliance with regulations, unlike uncertified alternatives.
