SUREPHON R1234YF Adapter – R1234yf to R134a Quick Coupler, High/Low Side Car AC Kit

Overview

The SUREPHON R1234YF Adapter is a compact, purpose built tool for automotive air conditioning work. It bridges R1234YF and R134A systems with an upgraded sealing design that combines a six-ball lock and a rubber seal to create an automatic closing connection. This design helps minimize leaks during conversion, recovery, and evacuation tasks, letting you focus on the service rather than fiddling with fittings. The brass body feels solid in hand, and the knurled grip makes secure handling easy even in a crowded engine bay. Its thoughtful design also makes it a practical companion for road trips or mobile technicians who need reliable, on the go cooling system service.

Dual color coded high and low side connectors

The red high side adapter and blue low side adapter are engineered for quick, secure hookups on both sides of the system. The high side part is a 17 mm female to 1/4 inch SAE male, paired with a 16 mm R134A quick coupler. The low side uses a 14 mm female to 1/4 inch SAE male with a 13 mm low pressure R134A quick coupler. Color coding helps you orient fittings at a glance, reducing mix ups during busy service sessions and speeding up your workflow when you’re working with manifold gauges or diagnostic tools.

Premium build for durable service

• Brass construction delivers lasting durability and reliable performance in typical workshop conditions.
