Tech Team #788 350-Count Zerk Grease Fitting Cap Assortment – Dust Covers for Grease Nipples, Brake Bleeder Screws & Hydraulic Fittings – Multi-Size Rubber Caps for All Equipment Types

When you’re working with vehicles, heavy equipment, farm machinery, or industrial tools, keeping your grease fittings clean is essential for preventing wear and costly repairs. The Tech Team #788 Zerk Grease Fitting Dust Cap Assortment gives you the perfect all-in-one solution. With 350 total pieces across 6mm, 8mm, and 10mm sizes, this kit covers almost every lubrication point you’ll encounter—making it a must-have for mechanics, fleet service shops, farmers, and DIY maintenance users. Zerk caps act as a protective barrier for grease nipples and brake bleeder screws, preventing dirt, grit, moisture, road salt, and debris from entering the lubrication system. When left uncovered, fittings can corrode, clog, or fail—leading to seized bearings, premature wear, and expensive downtime. These dust caps help you avoid all that by maintaining a clean lubrication point at all times. Each cap is built from durable, flexible pvc designed to resist cracking, UV damage, oil exposure, and extreme temperature fluctuations. Whether you’re maintaining an ATV, a tractor, a piece of construction equipment, or an industrial machine, these caps hold up in harsh conditions. The interior rib design grips tightly onto the fitting for a dependable, vibration-resistant hold, so the caps stay where you put them—even on equipment used daily. The assortment includes all three common metric sizes—6mm, 8mm, and 10mm—to ensure compatibility with a wide range of vehicles and machinery. Perfect for automotive shops that service multiple models, agricultural maintenance facilities that work with tractors and implements, and construction crews handling loaders, excavators, and skid steers. Whether you're performing routine lubrication or replacing old, cracked dust caps, this set gives you plenty of spares and replacements. A compact storage case keeps all 350 pieces neatly organized, making it easy to carry the kit between job sites or store it in your toolbox. With the Tech Team #788 Grease Fitting Dust Cap Assortment, you get a reliable, affordable way to protect critical lubrication points and keep your equipment lasting longer with less maintenance.
