Parker offers series of quick couplings with a British standard profile according to BSI. These British quick couplings are easy to use and, thanks to the one-handed operation, a quick and easy connection is possible. These quick couplings are equipped with an UltraFlo valve for optimum flow and low pressure drop. The quick couplings with interchangeable British industrial profile have a large insertion depth guaranteed by an optimised plug guide, making them a robust coupling with a slim design mainly for pneumatic applications.
