Everything a service port needs
Caps, cores & ports
Service caps, valve cores, and service-port fittings/seals together — the three things you touch on a port job.
R-134a & R-12
Covers both refrigerants, including R-12 flare caps and R-134a metric and retrofit caps.
Retrofit styles
Aeroquip, Eaton SSV, and JRA cap styles are all covered for OEM and retrofit fittings.
GM/Ford port rebuild
GM high- and low-side port fittings, adapters, and GM/Ford primary seals to rebuild a leaking service port.
Tool included
A universal valve-core removal tool (M8, M10, JRA, standard) is in the box.
