STXE wipers are designed to retrofit the standard ST wiper groove while providing superior performance. The o-ring energizer limits dirt intrusion around the O.D. of the wiper. The energizer also makes this wiper more effective in applications with severe side deflections.

Style ST-XL wipers are molded from premium urethane and are direct replacements for Style 'ST' or 'D' wipers. The outside diameter of the ring has a crush lip providing extra interference in the groove. A bead on the shoulder stops contaminants from entering through the groove. The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal.

Style RU9 seals are molded from MDI based Zurcon® Z25 urethane. This seal offers good elasticity with low compression set while maintaining a high level of tribological characteristics. The dynamic seal lip incorporates slide segments that will increase back-pumping capabilities while reducing friction. The RU9 style rod seal is ideal for hydraulic applications where high temperature and high pressure performance is required.SEAL INFORMATION MATERIAL 95A URETHANE TEMPERATURE RANGE -31° to +270° F PRESSURE RANGE 0 to 5,800 PSI SPEED 1.65 FT/SEC PART NUMBER (Prefix)(CS) - (ID) - (Height) MAXIMUM EXTRUSION GAP PRESSURE 1000 PSI 3000 PSI 5000 PSI 6000 PSI MAX DIAM.

Totally interchangeable with Style PS1400 PTFE piston seals, Style PS1500 piston seals are molded from tough 60 shore D durometer polyurethane. During the molding process, a .002 in. thick band of molybdenum is molded into the outside diameter of the seal ring for reduced friction. PS1500 piston seals are easily stretched over the piston and recover rapidly with the elimination of the 'cold flow' characteristics found in PTFE seals. Piston diameter 'F' dimensions are given for pistons without wear rings.

INSTALLATION OF PTFE PISTON SEALS
Installing PTFE piston seals is not always an easy task. The use of installation tools 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.

SCS Powerbands®
SCS Sealing Products is pleased to introduce our new line of Powerband® tight tolerance premium wear-rings. Manufactured from a highly engineered blend of premium nylon, glass fiber, and PTFE, Powerbands® offer a high strength wear-ring for all cylinder applications, including those with minimal lubrication. And, with a coefficient of friction nearly 50% lower than our standard product, your cylinders will run smoother and more efficiently than ever.All Powerbands® are fully machined with cross-section tolerances of only ±0.001 in, chamfered corners, and scarf or angle-cut end gaps. Compared to standard tolerances of ±0.0025 in., this tightened tolerance improves the alignment and concentric operation of cylinder rods and pistons. The fully machined chamfered corners will better accommodate cylinder housing grooves, further improving piston and rod alignment. Lastly, the scarf-cut end gap reduces the loss of bearing support that may occur during cylinder side-loading. When combined, these features reduce the tolerance stack-up within the components of the cylinder. As a result, your cylinders will operate more consistently and be capable of operating at higher pressures and higher side loads than with standard wear-ring products. Furthermore, with this improved cylinder operation, your seals will last longer and the life of your cylinder will be extended. Powerbands® are currently available in our most popular wear-ring dimensions, as shown here. If you do not see your size or would like more information on this innovative product, please contact SCS.

Style DRTU-BHT rod seals are molded in Freudenberg® AU 30000 urethane. These seals are specifically designed with a second lip on their inside diameter and engineered to attain maximum life and reliability in dynamic rod sealing. This feature results in reduced leakage, less friction, increased stability, and prevents air and contaminants from entering the cylinder. This high tear-resistant urethane demonstrates stability throughout a wide range of temperatures. In addition, this material is well suited to mineral and biodegradable hydraulic fluids as well as being resistant to hydrolysis.SEAL INFORMATION MATERIAL 94A URETHANE TEMPERATURE RANGE -31° to +250° F PRESSURE RANGE 0 to 7,250 PSI SPEED 1.5 FT/SEC PART NUMBER (Prefix)(CS) - (ID) - (Height) MAXIMUM EXTRUSION GAP PRESSURE 1000 PSI 3000 PSI 5000 PSI 6000 PSI MAX DIAM.
