The Parflange F37 flanged connector system is utilising the orbital tube forming technology for tubing assemblies from 16 to 273 mm (1/2" to 10" Flanges) outside diameter. It is intended for tube wall thickness up to 9 mm and pressure ratings up to 420 bar. For those connections without the 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 1/2" to 10" and as a newly developed SAE 1000 (50-70 bar) version. The Parflange F37 system corresponds to hole patterns according to ISO 6162-1; SAE J518; bore pattern 3000 (code 61), ISO 6162-2; bore pattern 6000 (code 62) and also ISO 6164 bore pattern. It is type approved by DNV, ABS and other major classification companies.

Innovative Sealing Solutions The F37 seal was developed especially for use with SAE flanges. These special seals guarantee high stability of form. Compared to standard O-Rings, their mechanical properties prevent gap extrusion, even when the flanges ”breathe” under pressure. The special profile of the F37 seal is ideally adapted to higher pressures or unsuitable surface finish of the flanges. As an alternative, connectors can be equipped with bonded seal rings.

Complete range for virtually all diameters The F37 system complements the EO-2 soft sealing technology for small tube diameters; it also complements the proven Parflange programme for the SAE product range. It offers the complete range of connectors, flange-to-flange, L-and T-Block connectors, flange-to-port, male and female thread flanges, flange bends, reducer flanges, ball valves, bulkhead flanges and manifolds on request.
