Low pressure gauge group D80 R134a/1234yf

This set covers both R134a and R1234yf, so you can handle the two most common refrigerants in modern vehicle air conditioning without switching tools. The low-pressure gauge gives you a clear read on the suction side, which is where you spot the early signs of a weak compressor or a blocked system. Whether you are diagnosing a slow leak or checking performance after a recharge, having the right manifold readings makes the job straightforward.
