Description
The Mastercool 82834 High-Side Manual R134a Quick Coupler is designed for reliable connection to high-side service ports on automotive air conditioning systems using R134a refrigerant. Because it uses a manual locking design, technicians can maintain positive control during connection and disconnection, which helps support safe and accurate service procedures.
This coupler features a 14 mm female inlet and a 16 mm quick-connect interface, allowing seamless integration with standard R134a service hoses and manifold gauge sets. As a result, it supports common charging, recovery, evacuation, and diagnostic workflows. In addition, the durable construction helps maintain a tight seal under pressure, reducing the risk of leaks during service.
