Claron Polyseal Static Flange Seal CFS

Design:

Claron style CFS flange seal is designed to suit the SAE J518 range of flanges, and common metric flange sizes.

The seal is manufactured in Claron’s high performance grade of Polyurethane with excellent resistance to extrusion and compression set over a wide temperature range. The design offers many performance advantages over common o-ring, or rubber based flange seals, including the elimination of the ‘pumping effect’.

Operating conditions:

Max. Pressure	Temp Range
400 Bar	-40 to 110°C

These range perameters are Maximum simultaneous conditions. Optimum service conditions are affected by temperature, pressure, surface finish and extrusion gaps.

Refer to Appendix 1 for further information.

Housing:

For surface finish and recommended lead in chamfers refer to the illustration below. For housing dimensions and machining tolerances refer to the catalogue page of selected seal.

Fitting:

For the seal to function correctly, it is important that care be taken in fitting the seal within its housing.

For a detailed checklist, refer to Appendix 3.
