The type-tested refillable WAECO bottle for R134a refrigerant has successfully proven itself in daily workshop use for decades. Naturally, we now also offer a version for the new refrigerant R1234yf – clearly recognisable by the signal red colour of the stand-up collar. Avoiding any risk of confusion! All refrigerant bottles come with a refill safety device to protect you and your service tools. Also, since the bottles don't have a riser tube, it's possible to extract the refrigerant in gas or liquid form. Suitable for all charging units in mobile or stationary use.
