Description
Overview:
The G-Coupler Lock n Lube Type Grease Gun Connector is a robust, all‐metal lock‐on coupler designed to make greasing quicker, cleaner, and more secure. Its spring‐loaded mechanism grips the grease nipple firmly for hands‐free operation, helping to prevent blow‐off at high pressure. The connector has a 1/8" BSP thread (approx. 3.2 mm nominal) to suit most grease hoses and rigid pipes on manual, air, and battery grease guns. Rated to 10,000 psi (approx. 689.5 bar), it is suited to demanding workshop and site use on construction and garden machinery. Ideal for routine servicing on compact excavators and similar plant, including popular models such as the 18Z-1 and 19C-1, it delivers reliable performance for everyday maintenance tasks.
Key Features:
- 1/8" BSP thread (approx. 3.2 mm nominal) for broad grease gun compatibility
- High-pressure rating: 10,000 psi (approx. 689.5 bar) for tough applications
- Spring-loaded, lock-on jaws for secure, hands-free greasing and reduced leakage
- All-metal construction with a grippy knurled sleeve for easy attachment and release
- Compact head helps access confined fittings on crowded linkages and frames
- Works with standard grease nipples (zerk fittings) commonly found on plant and garden machinery
- Smooth release reduces back-pressure and minimises mess around seals and joints
- Suitable for manual, pneumatic, and cordless grease guns used in workshops and on site
- Brand: G-Coupler; Manufacturer Part Number (MPN): 115
- Built for durability and repeat use in high-duty maintenance schedules
Typical Applications:
Daily and scheduled greasing of pins, bushes, bearings, linkages, U‐joints, and pivot points on excavators, compact loaders, backhoes, trailers, agricultural implements, and commercial mowers. Ideal for plant hire, construction sites, service vans, and farm workshops where fast, clean, and reliable lubrication is required under high pressure.
