Filling hose adapter 5/16" M to 1/4" F
The filling hose adapter is used when the existing connection of the filling hose is not compatible with the connection to be connected.
The connection of your filling hose is 5/16" SAE (female/internal thread). However, you need a 1/4" (female/internal thread) connection that you want to screw onto the 1/4" SAE (male/external thread) connection.
Then this is the appropriate adapter.
• 5/16" SAE male (external thread), with Schrader valve
• 1/4" SAE female (internal thread), with valve depressor
• suitable for R407c / R22 (TR422ABCD) refrigerants
• 500 PSI - 45 bar (maximum operating pressure for R407c / R22 (TR422ABCD))
• 1x straight filling hose adapter, 5/16" SAE male (external thread) with Schrader valve to 1/4" SAE female (internal thread) with valve depressor
