FITTINGS 1/4"-28 THD SHRT - Lincoln Industrial

The Lincoln Industrial G630 Grease Fitting is a robust 1/4"-28 short, straight fitting engineered for reliable lubrication in demanding professional environments. Designed for efficiency and durability, this component ensures critical bearings receive consistent grease delivery, essential for maintaining optimal equipment performance and extending service life. It is an indispensable part for automotive and industrial maintenance professionals.

Key Features

• Precision 1/4"-28 Thread: Features a standard 1/4"-28 UNF thread, ensuring compatibility with a wide range of existing equipment and lubrication systems.
• Durable Construction: Manufactured from high-quality materials, typically zinc-plated steel, to resist corrosion and withstand the rigors of industrial and automotive use.
• Integrated Ball Check: A specially designed ball check in the head of the fitting prevents the ingress of dirt and grit, protecting bearings from contamination.
• Optimal Lubricant Flow: The internal spring is tempered and coiled to prevent compression that could restrict the flow of heavy lubricants, even under high pressure.
• Secure Connection: Features a true spherical contour on the fitting head, providing a natural ball-and-socket joint for a tight, metal-to-metal seal with commercial hydraulic grease couplers.
• Compact Design: The "short" designation allows for installation in tight or confined spaces where standard fittings may not fit.

Applications

The Lincoln Industrial G630 grease fitting is vital for routine maintenance across various sectors. It is commonly used for chassis lubrication on cars and light trucks, as well as in demanding heavy equipment applications such as construction machinery, agricultural equipment, and large industrial machinery. This fitting provides essential lubrication points to minimize friction and wear, preventing costly downtime and extending the operational lifespan of mechanical systems.
