The Lumatic HC5 is a professional-grade, 4-jaw hydraulic connector ideal for technicians and mechanics who require a consistent, leak-free grease application. Designed specifically for heavy-duty grease guns and hydraulic grease nipples, this tool provides a highly secure connection that prevents waste during high-pressure lubrication tasks, though it requires users to ensure their existing equipment utilizes a standard 1/8in BSP thread for proper compatibility.

The HC5 is designed for standard hydraulic grease nipples. It may not be compatible with button-head or flush-type fittings.
Yes, the HC5 is built for heavy-duty use and can handle the pressures generated by most pneumatic grease guns.
BSP stands for British Standard Pipe. It is the thread standard used to ensure the connector screws correctly into your grease gun hose.
Replace the connector when you notice the jaws failing to lock onto nipples or when excessive grease leakage occurs despite a clean, functional nipple.
No, the Lumatic HC5 is a fixed, standard hydraulic connector.
Check the grease nipple for excessive dirt or damage; clean the nipple or replace it if the head is deformed.
Ensure the coupler is pushed firmly onto the nipple. If leaking persists, check the 4 jaws for wear and replace the connector if they no longer grip securely.
Verify that your grease gun hose uses a 1/8in BSP thread. If it uses a different thread type, a thread adapter will be required.
To install the Lumatic HC5, simply unscrew your existing coupler from the grease gun hose and thread the HC5 onto the 1/8in BSP fitting. Ensure the connection is tightened securely with a wrench, but avoid overtightening which may damage the threads. The unit is compatible with any standard manual or pneumatic grease gun featuring a 1/8in BSP outlet. For maintenance, regularly wipe the jaw area with a clean shop rag to remove grit. If grease begins to leak from the connector during use, inspect the internal jaws for wear or debris buildup that may be preventing a proper seal.
