Specialised Flange Seal Outperforms O-Rings in SAE J518 Flanges.
Specialised seals to suit SAE J518 Flanges have now been introduced
by Claron Hydraulic Seals Ltd.
Called style CFS, the seals are manufactured from a high performance
grade of Polyurethane which has been developed specifically for
arduous sealing applications. The material provides excellent
resistance to gap extrusion and compression set over a wide temperature
range of -40°C to +110°C at up to 400 Bar.
SAE J518 standard was introduced by the American Society of Automotive
Engineers to cover hydraulic flanged tube, pipe, and hose connections,
including four-bolt split flange types used in the design and
maintenance of self-propelled vehicles for use on land, sea, air
or in space. The SAE J518 flanges, which have been designed to
avoid the use of threaded connections, also have a wide range
of general hydraulic applications and are being used on earth
moving machines, and power steering systems manufactured around
common O-Rings, Claron CFS style seals are specifically designed
to fit the SAE J518 location groove. With their rectangular cross
section and point contact sealing lips, they are formed and sized
to accurately locate within the machined housing.
Their design provides superior performance to both O-Rings and
rubber flange seals, while eliminating the 'pumping effect' which
is common to close fitting O-Rings.
seals are available in six standard SAE J518 sizes from 0.500"
to 2.000", together with two metric sizes of 33.5x26.3 and
Claron for further information on CFS style seals.
