UB20 series pneumatic quick couplings are a variant of the UA20 series and conforms to ISO6150-B standard and can be compatible with ARO210, industrial interchange 1/4” and Tru-Flate nipples. One female coupler can be interchanged with IN20, TR20 and AR20 plugs freely. It is usually made of carbon steel with nickel plated or brass with acid pickling.
The maximum working pressure is 2.0MPa. If it is replaced with fluorine rubber FKM, it can also work under high temperature conditions. Compared with the UA20 series, the UB20 series has smaller size, lighter weight, lower cost, and simple operation, safe and reliable, but its flow rate is less than that of the UA series. The push-to-connect structure is easy for one hand operation. UA20 series is available for 1/4" flow rate body only. If you need a larger flow rate, it is recommended to choose EU20, or IN30, IN40 series.
