This is a 12 oz can of straight R134a refrigerant from B'laster, sold as a refill for automotive air conditioning systems. It contains no additives, dyes or seal conditioners, so it is plain gas for topping up a system that is already set up for R134a. That makes it a fit for DIYers who own a manifold gauge set or recharge kit and want to add refrigerant without extra chemicals. Against rivals, it is the bare-bones option: cans with leak sealer or UV dye cost more and add ingredients some technicians avoid, while this one keeps the system chemistry unchanged.
