Concerned by what o-ring you will need for your vehicle’s air conditioning system? Don’t know which one you may need? Each kit is manufactured for a specific application, it has all the o-rings and seals you need for the entire system. All O-Rings are made from NHPR, universal to both R12, R134a and R1234YF systems.
TIP: Always coat your o-rings with mineral oil for a better seal and ease of removal later, never use old or used o-rings, they tend to leak when the system is recharged.
