It boasts an 18-inch flex hose extension, making it suitable for hard-to-reach fittings, and offers universal fitting compatibility, which enhances its versatility across different tasks. The convenience of one-hand operation allows for easier and more efficient greasing, particularly beneficial in tight spaces or when operating machinery single-handedly.

The heavy-duty cast-alloy head with reinforced wall thickness ensures durability and strength, capable of withstanding rigorous use. It can develop pressure up to 7,000 PSI, making it suitable for high-pressure applications, which is a significant advantage for challenging greasing tasks.

Manufactured by Lumax, this grease gun weighs 2.5 pounds and has dimensions of 15 x 5 x 2.8 inches, making it relatively compact and easy to handle. Given its strengths and minor drawbacks, this grease gun is a solid choice for mechanics, DIY enthusiasts, and anyone in need of a durable and efficient greasing tool.

The LUMAX LX-1406 grease coupler is designed to work with most hand-operated grease guns, making it a versatile choice for general maintenance tasks. It features a 1/8 inch NPT female thread size, a common fitting type, so it fits many standard grease guns easily. One of its main strengths is the 360-degree swivel function that locks in place, allowing you to move the fitting freely around grease points without disconnecting. Additionally, the 45-degree angled tip helps reach grease fittings in tight or awkward spaces, adding convenience especially for hard-to-access areas.

With a pressure rating of up to 4,500 PSI, this fitting handles the pressure of most routine lubrication jobs without trouble. It is lightweight and compact, making it easy to handle during use. While it fits most hand grease guns, it may not be compatible with specialized or high-end models that require different thread sizes or types.

This grease coupler is a strong candidate for anyone looking for a reliable, flexible fitting that simplifies greasing tasks on vehicles or machinery. It is especially helpful for users needing better access to grease points with its swivel and angled design. For general automotive or light industrial maintenance, the LUMAX LX-1406 offers a practical and effective solution, though those needing fittings for very high-pressure industrial use or specific material qualities might consider other options.

The LUMAX LX-1400-6 grease coupler is a solid choice for anyone needing a reliable fitting that connects easily to standard grease guns with 1/8" NPT female threads. It is designed with four hardened steel jaws, which means it’s durable and can withstand repeated use without wearing out quickly. The spring-loaded ball check valve is a handy feature that helps prevent grease leakage, keeping your workspace cleaner and reducing waste. Its small outside diameter and knurled body make it easier to install and remove, especially in tight or recessed areas where access may be limited.

With a maximum operating pressure of 4500 PSI (310 Bar), it is well-suited for most automotive and machinery greasing needs, offering enough strength for heavy-duty use without being overkill for standard applications. The fitting's compatibility with all 1/8" NPT threads ensures it will connect smoothly with many grease guns and equipment. However, the product is made in China and is painted rather than stainless steel, so while it holds up well, it may not have the same corrosion resistance as more expensive metal options.

Customers have rated it positively, averaging 4.4 out of 5 stars, reflecting satisfaction with its performance and value.
