[APPLICATION]: Grease fittings, sometimes known as Zerks or grease nipples, are small hydraulic check valves used on bearings and similar mechanical assemblies to supply lubricant to internal working parts.
[HYDRAULIC GREASING]: These grease zerks feed lubricant into a bearing instead of having to disassemble parts to apply the lubricant, which makes for effective work efficiency when using a grease gun.
[COMPATIBILITY]: This assortment kit is perfect for use on cars or vehicles and solves OEM incompatibility issues with straight, 90-degree and 45-degree angled fittings to allow a pressure-resistant connection.
[CONVENIENT]: The plastic storage case contains each SAE grease zerk fitting in the kit in different compartments with an organization chart to neatly stay organized in your tool collection.
[INCLUDES]: Sizes - 30 straight 1/4-28, 20 straight 1/8" pipe grease, 15 45-degree, 1/4-28 and 15 90-degree 1/4-28 for angled grease guns and more.
