#VAC4 All-Models Shop Vac Adapter

The shape of this adapter should allow it to fit most tractors. Its smaller tip and wide sealing surface will accommodate a range of fill-port sizes.

Validated on a range of New Holland models including WorkMaster and PowerStar tractors. Please check your tractor before ordering. 22mm or 7/8" tip, 1 3/4" sealing surface. 

This adapter allows you to connect a shop vac to the hydraulic reservoir fill port to apply slight vacuum pressure.  By applying this controlled vacuum, the internal fluid level is held under tension, effectively preventing hydraulic fluid from draining out of open lines, fittings, or filter housings when components are disconnected for maintenance. Always ensure vacuum pressure is applied gently—too much suction could damage seals or draw contaminants into the system. This adapter provides a safe, effective method for performing clean and efficient hydraulic maintenance.

Key Benefits:

• Minimizes hydraulic fluid loss during service
• Helps prevent air from entering the system
• Reduces cleanup time and environmental waste
• Compatible with standard shop vac hoses
• Simple and reusable tool
