Reliable Industrial Connections for Precision Lubrication
The Hydraulic Coupler series offers professional solutions for connecting grease guns to standard hydraulic-type grease nipples. Whether you need a cost-effective everyday tool or a high-performance leak-free connection, these 4-jaw couplers provide the durability required for industrial maintenance. Both models feature a slim 15 mm diameter, allowing them to fit into tight spaces where larger connectors might struggle.
Standard 4-Jaw System
Is the industry-standard choice for general lubrication tasks. It features a reliable stamped-metal jaw system that provides a firm grip on standard nipples. While highly effective for routine maintenance, this model is best suited for applications where back-pressure is moderate. If a grease nipple is slightly damaged or chipped, the stamped jaws may allow a small amount of grease to “weep” or spray from the connection point under extreme pressure.
Precision 4-Jaw System
For professionals who demand a “leak-free” experience, the Precision Coupler is the superior option. The internal 4-jaw mechanism and the high-grade rubber seal are precision-machined to much tighter tolerances than the standard version. This ensures a much tighter seal and a more secure grip, even when dealing with high back-pressure. It effectively prevents grease from squirting out the sides, ensuring every gram of lubricant reaches the bearing, keeping your machinery and workspace cleaner.
