    SCS offers material advantages of with our family of urethanes in standard o-ring sizes. The high extrusion resistance and related compounds eliminates the need for a back-up in many hydraulic applications, thereby simplifying installation and reducing groove width. Our unmatched temperature rating makes it suitable in applications where other urethanes fail. In addition, Our O-rings provides superior water resistance and compression set resistance in water-based fluids. Premium urethane o-rings are much less prone to spiral failure and installation damage compared with rubber o-rings. Dimensions and tolerances of our o-rings match up with AS568B specifications for diameter and cross-section and are used in the same grooves. 90D = 90 Durometer B = Bulk (Min Quantities) V = Viton (Fluorocarbon) T = 55-58 Shore D PTFE U = 90A Urethane V-BLACK = Black Viton (Fluorocarbon) EP = Ethylene Propylene S = Silicone

    To obtain best results from any style of piston cup, it is recommended that the piston properly support the heel of the cup. Recommended diametral clearance between the piston and cylinder wall are as follows:
    1" to 2-1/4" .005"
    2-1/2" to 4-3/4" .008"
    5" to 10" .010"

    The height of the machined shoulder most frequently used to control squeeze on the heel of the cup is as follows:
    Cups 1/8" thick .116/.119"
    Cups 5/32" thick .146/.149"
    Cups 3/16" thick .178/.181"
    The follower plate should be approximately .110" smaller than the ID of the cup. To reduce any tendency of the cup to extrude under pressure a phonograph finish may be machined on the surface of the follower plate.

    INSTALLATION OF PTFE PISTON SEALS
    Installing PTFE piston seals is not always an easy task. The use of installation tools (Designated by a 'CTC-' product code prefix) is recommended but often not convenient when working with a wide variety of sizes and applications. Finger installations are practical with rings of smaller cross-sections. Using fingers or a rounded plastic stick, knead the ring over the piston into the groove. With rings of larger cross-sections it may be necessary to heat the ring. Warming the ring in water or oil at 130° F or 140° F for about 5 minutes will soften the material for easier installation. Always avoid inconsistent stretching or overstretching of the PTFE seal.

    To prevent the PTFE ring from snapping into the wrong groove, cover wear ring grooves with plastic tape.

    After seal installation, assembly of the cylinder may be difficult if the piston seal is loose on the piston or the cylinder has an inadequate leading edge chamfer. In such cases, compress the piston seal with belting or a suitable hose clamp. If the piston seal must pass threads or any other sharp edges during the cylinder assembly, cover the edges with plastic tape or wrap. Note: Caterpillar part number are used as a refernce only.
