Six-ball grip design with integral safety sleeve protection

Professional-grade high side service coupler designed for R-134A automotive air conditioning systems. The 6-ball grip design provides 50% more contact points than standard couplers, ensuring secure connections during refrigerant service. Integral safety sleeve prevents injury and refrigerant loss if disconnected under pressure.

Key Features

Six-Ball Grip Design

Provides 50% more contact points than traditional four-ball couplers, delivering superior grip stability and reducing the risk of accidental disconnections during service operations.

Integral Safety Sleeve

Automatically seals the connection if accidentally disconnected under pressure, protecting against personal injury and preventing costly refrigerant loss on systems exceeding 200 PSI.

90-Degree Angle Design

Allows easy access to service ports in tight engine compartments where straight couplers won't fit, reducing strain on hoses and service ports during retrofit work.

Red-Coded for High Side

Color-coded identification prevents connection errors. Fits R-134A 1/4" SAE high-side service ports and works with Robinair Enviro-Guard hoses.
