Parker is the inventor of the Parflange system and knows well how to deal with flared tubes and flanged connectors. The excellent sealing performance and the high mechanical strength of Parflange technology are achieve by continuous orbital tube forming. The Parflange system belongs to Parkers’s leak-free Dry Technology programme. Dry Technology stands for leak-free systems with soft sealing at every connection point.

The Parflange F37 flanged connector system is utilising this orbital tube forming technology for tubing assemblies from 16 to 165mm (1/2” to 6” Flanges) outside diameter. It is intended for tube wall thickness up to 9mm and pressure ratings up to 420 bar. For those connections, where there is no possibility to assemble a pre-flared tube or where manufacturing is limited, Parker provides the F37 Retaining Ring System. This System utilizes a Retaining Ring for flange retention along with a highly-engineered seal carrier for leak free performance. It is available as a high pressure version from 1 ½” to 10”.
