LANNIU Grease Gun Coupler Kit 12000 PSI — 0.53" Low-Profile Head with 90° Adapter & 2mm Needle

Whether you work on farm equipment, construction machinery, or everyday vehicles, this kit is built to make greasing fast, clean, and reliable. The kit combines a patented 6-jaw coupler with aviation-grade gaskets, a compact profile for cramped fittings, and accessories that let you reach recessed grease points without mess. It fits all standard 1/8" NPT grease guns and is made from nickel-plated carbon steel for long service life.

How does the 6-jaw design prevent grease leakage?

The patented 6-jaw arrangement clamps uniformly around fittings to create a tight seal and minimize blowback during grease injection. Aviation-grade gaskets add a secondary seal so you get a mess-free connection even at high pressure. The assembly was pressure-tested to 12,000 PSI for dependability under demanding conditions.

• US-patented 6-reinforced jaws for even grip
• Aviation-grade gasket seals against blowback
• Tested to 12,000 PSI for industrial reliability

What makes this kit useful for tight or recessed fittings?

The coupler head is just 0.53 inches in diameter, allowing one-handed attachment in cramped areas where standard couplers won't fit. The 90° adapter pivots grease flow into hard-to-reach angles, while the precision 2mm needle tip feeds lubricant into tiny holes and pin joints. A cleaning tool is included to keep the needle clear for repeatable accuracy.

• 0.53" low-profile coupler for narrow access
• 90° adapter for angled or obstructed fittings
• 2mm needle tip for precision lubrication of small parts
• Cleaning tool to maintain needle performance

Is this coupler kit compatible with my grease gun and fittings?

Yes — the kit uses a universal 1/8" NPT thread that fits most manual, pneumatic, and electric grease guns. It also works across standard SAE and Metric zerk fittings, reducing the need for multiple adapters. This compatibility makes it a practical addition to any mechanic’s toolkit.

• Standard 1/8" NPT thread fits most grease guns
• Works with both SAE and Metric grease fittings
• Suitable for manual, pneumatic, and electric guns

How durable is the LANNIU kit in everyday workshop use?

Every component is made from nickel-plated carbon steel to resist wear, corrosion, and impact in rugged environments. The reinforced jaws and high-pressure testing mean the kit holds up during heavy and repetitive use. It’s intended for automotive repair, agricultural machinery, construction equipment, and home garages where reliability matters.

• Nickel-plated carbon steel resists rust and wear
• Reinforced parts for longer service life
• Designed for frequent use in demanding settings

Who is this for: The LANNIU Grease Gun Coupler Kit is for mechanics, farm operators, fleet maintenance teams, and serious DIYers who need precise, leak-resistant lubrication in confined or awkward locations. If you want a compact coupler that locks securely, reaches tight fittings, and endures frequent use, this kit is tailored for those needs.
