134pcs Car Air Conditioner Valve Core R134a Kit, AC Valve Core Automotive Air Conditioning Refrigeration A/C Valve Stem Cores, sliver

This is a good assortment of automotive air conditioning valve cores. My vehicle’s air conditioning system has a leak and it needs a replacement hose part so I’m going to replace the valve cores while the system is fully evacuated of freon. These valve cores can be a source of refrigerant leaks as the o-rings can become degraded over time. My only critique is that this kit would’ve been more complete if they would’ve included a torque driver for properly installing the new valve cores at the proper torque rating to prevent over tightening or under tightening. I would recommend.
