Mastercool Valve Core Depressor Tool

The Mastercool Valve Core Depressor Tool line offers replacement valve core depressors (also called hose depressors or charging hose depressors) for A/C and refrigeration service hoses. The depressor sits inside the hose fitting. It pushes open the Schrader valve core in a service port when the hose is connected, so refrigerant can flow during charging, recovery, and evacuation.

Key Features:

• Replacement part for Mastercool-style A/C charging and service hoses
• Restores proper service port valve actuation when an old depressor is worn, damaged, or missing
• Made for professional A/C service work
• Simple to install in the hose end fitting
• Backed by Mastercool, a supplier of A/C and refrigeration service tools and equipment

Keeping fresh depressors in your service kit helps your hoses seal and connect reliably to service ports. Choose the variant that matches your hose fitting.
