Description

The Mastercool 82934 Low-Side Manual R134a Quick Coupler delivers a reliable connection to low-side service ports on automotive air conditioning systems using R134a refrigerant. Because it uses a manual locking design, technicians maintain positive control during connection and disconnection, which supports safe and accurate service work.

This coupler features a 14 mm female inlet paired with a 13 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 procedures. In addition, the durable construction helps maintain a tight seal under pressure, reducing the risk of leaks during service.

Designed for professional shop and mobile environments, the Mastercool 82934 provides dependable performance wherever R134a systems are serviced.
