Creative design - An anti-slip strip on the grip and a double-grip design provide enhanced palm grip and reduce hand fatigue. Simple press on both grips enables effortless locking or unlocking of the grease gun coupler at the nozzle. Durable strength - Made from high-quality alloy steel for long-term use with a strong, deformation-resistant structure. The design offers good spring elasticity and high toughness to withstand demanding work. Wide compatibility and applications - Fits all types of lubricators and is professionally engineered for a variety of machines. Its flexibility makes it suitable for use with excavators, bulldozers, tractors, harvesters, and more. Easy to use - Features a user-friendly clamping locking mechanism and a nozzle that extends outward and locks firmly, greatly simplifying the lubrication process. The extended design prevents axial bending, and the improved joint facilitates easy maintenance. Use scenarios - Maintenance on heavy construction equipment such as excavators and bulldozers during routine lubrication. - Agricultural servicing for tractors and harvesters to ensure efficient, leak-free lubrication points. - General machine maintenance across industrial equipment that uses standard lubricators.
