Mastercool 83735 R1234yf Adapter – 12mm-M × 14mm-F

Description

The Mastercool 83735 R1234yf Adapter (12mm-M × 14mm-F) delivers a reliable solution for connecting R1234yf service components with differing thread sizes. Because modern A/C systems often require mixed-size fittings, this adapter helps technicians complete service work without changing hoses or manifolds.

This adapter supports common R1234yf service workflows, including charging, recovery, evacuation, and diagnostics. As a result, technicians can maintain proper connections while reducing setup time. In addition, the precision-machined design helps ensure a tight seal under pressure, which supports clean, accurate service.

Designed for daily professional use, the Mastercool 83735 integrates seamlessly with R1234yf manifolds, hoses, couplers, and recovery equipment used in automotive A/C applications.
