Zeeline NPT Straight Grease Fitting

Zeeline NPT straight grease fittings, also called grease nipples or Zerk fittings, give you a dependable point to deliver lubricant into bearings, joints and other moving parts with a standard grease gun. Zeeline by Milton designed them for fleet and plant maintenance.

Key Features:

• Straight (0 degree) body style for direct, in-line access with a grease gun coupler
• NPT tapered threads that seal as they are tightened into a threaded port
• Brass construction that resists wear from constant use
• Built-in check ball that opens under grease gun pressure and closes afterward. This helps keep grease in and dirt out.
• Standard-style head that works with common grease gun couplers

Replacing worn or damaged fittings helps keep lubrication reaching critical components. That supports longer component life and less downtime in automotive, equipment and industrial maintenance. Select the child item that matches the thread size you need.
