Introduction
Connection technology
The Parflange® F37 Programme consists of two flange connection technologies:
The 37° Flare Flange Connection and the Retaining Ring Connection.
Parflange® F37 Flare Flanges
– In this configuration, the deburred tube end is flared orbitally to 37° by Parflange®
technology. An insert, soft sealed by an O-Ring, is located into each pipe end. In between a F37 Seal (optionally Bonded
Seal or O-Ring) is placed. By tightening the flanges together, a soft sealed, high pressure tube connection is made.
Available as tube-to-tube connection or tube-to-port connection.
Retaining Ring Connection
– The retaining ring used in this connection is a stainless steel segmented ring covered
by a stainless steel spring. It is assembled in a machined groove on the tube end or adapter. When tightening this
system, the flange is pushed against the retaining ring, thus giving a form tight connection. Retaining ring connections
complete the Parflange® F37 range with bulkhead, male, female, weld and tube bend connections.
