LockNLube® Grease Coupler XL - incl spare rebuild kit

Overview

The LockNLube® Grease Coupler XL (GC81032) is designed for hardware and tool applications requiring a secure, leak-free connection to standard grease fittings across all grease gun types.

Technical Features

• Locks onto grease fittings and does not release under pressure — eliminates coupler pop-off mid-application, preventing grease loss and mess on the machine surface.
• Zero-leak seal once locked on — ensures all grease is directed into the fitting rather than escaping at the coupler joint, reducing waste and contamination.
• No-hands alignment required — the coupler locks and holds its own position, freeing both hands to operate the grease gun for improved control and efficiency.
• Extended XL body length — provides additional reach compared to the standard original coupler, enabling access to fittings recessed behind shields, guards, or tight enclosures.
• Compatible with all grease guns and grease fittings — offers broad interchangeability across equipment brands and fitting types without requiring adapters.
• Includes a spare rebuild kit — extends service life of the coupler by allowing internal components to be replaced rather than discarding the entire unit.

Applications

• U-Joints — the XL length reaches fittings on universal joints that may be partially obstructed by surrounding driveline components.
• Harvester heads — suits the dense, shielded lubrication points common on agricultural harvesting machinery.
• Shielded PTO shafts — accesses grease fittings located behind or within PTO shaft guards without requiring shield removal.
• Fittings buried deep behind shields or guards — the extended body bridges the gap between the grease gun nozzle and hard-to-reach lubrication points on any machine type.
• General equipment maintenance — compatible with all machines requiring standard zerk fitting lubrication.
