IronGrip grease nipple coupler with dual-handle lock

The coupler slips off and the grease ends up everywhere except in the bearing.

Anyone working on tight bolts with a conventional one-handed coupler knows the result: scraped knuckles, grease on the frame, and half the cartridge wasted. The IronGrip Dual-Handle Locking Coupler locks onto the grease nipple, holds securely without needing to be held, and frees both hands for pumping. The grease goes directly into the bearing – not on the machine, not on the floor, not on you.

Benefits

• No more scraped knuckles: The dual-handle locking mechanism holds the coupler firmly on the grease nipple even under full pressure – no more annoying slipping or having to reposition in tight spaces.
• No more wasted grease: The 12,000 PSI internal seal presses every drop directly into the bearing, so you won’t lose half cartridges or have to repeat the greasing process constantly.
• No replacement after one season: The hardened steel housing with a high-strength spring withstands years of daily use – you won’t have to worry whether the coupler will still work on your next job.

Specifications

• Pressure resistance: Up to 12,000 PSI
• Thread type: 1/8" NPT
• Compatibility: Standard & metric grease nipples (90°, 45°, and straight)
• Material: Hardened steel
• Locking system: Double spring jaws
• Drive: Pneumatic, battery-powered, or manual

Usage

1. Screw on: Hand-tighten the IronGrip onto the 1/8" NPT thread of the grease gun – hand-tight is sufficient.
2. Lock in place: Press both handles, place the head on the grease nipple, and release – the jaws automatically grip and lock securely.
3. Pump & release: Pump with both hands, then squeeze the handles, pull off, and move on to the next fitting.

Pro tip: For deeply recessed or hard-to-reach grease nipples on tractor joints, use a 90° adapter between the gun and the IronGrip – this lets you reach every fitting without having to angle the gun awkwardly.
