Specialty Sealing Technologies takes pride in designing and manufacturing innovative hydraulic seals made from the highest grade materials. We offer the standard size seals along with non-standard sizes supplied both in English and Metric sizes. When we mold non-standard sizes, we do not charge any mold or set-up charges. All of our molds are manufactured from steel and we do not use any temporary molds. that ensures the correct tolerances are the same if it’s the first seal or the 1000th seal. All of our molds are manufactured at our facilities so that we can keep the correct procedures the same. We can mold endless seals up to 110″.
We carry a full range of materials and compounds such as NBR (nitrile Buna rubber), HNBR (hydrogenated nitrile buna rubber), Viton (DuPont) fluoroelastomer, EPDM, Neoprene, XNBR, and more of the elastomers. We also have a wide range of Thermoplastics PU (Polyurethane), Cast Polyurethane, Teflon (PTFE), BFT (Bronze loaded Teflon), GLT (Glass loaded Teflon), GRT (Graphite loaded Teflon), PE, Delrin, Peek, UP (Polyester Resin Bonded Fabric) and more. All of these are milled in house.
SST supplies a multitude of industries across the globe including forging, steel mills, hydroelectric, extrusion, and injection molding. Plus, we supply distributors, OEM’s, cylinder manufacturers, cylinder rebuilders, and machine rebuilders. We have hands-on experience in all of these markets and industries. We understand the effort and time it takes in working on all this machinery, so it’s important to supply the right product for the job and application to remove any added stress to the customer. That is why we want to provide the customer with a wide range of quality products to ensure that the equipment works properly.
SST supplies a robust style of packing for the forging and extrusion industries which needs these types of seals because of all the extra lateral movement of the rams. We have seals for all the smaller applications such as pullback, container, and die cylinders. For the steel mills, we have dozens of different styles of bearing/oil seals depending on the applications for the hot & cold mills, continuous caster, and other applications. The wood industry has different mills like plywood, OSB, Particleboard, LVL, and Hardboard. SST has supplied seals & wipers for Washington Iron, Motalla, Dieffenbacher, Williams White, Simplekamp, Fjellman, and Globe pre-presses with a free-floating style of packing.
We’ve supplied seals for the main rams, jack rams, and loaders & unloaders. The hydroelectric industry is a major user of our products. SST has supplied seals for Kaplan, Francis, Bulb, and Pelton units. The main applications are for the Kaplan blade seals, Wicket gates, servo-motors, and brakes. We have supplied end-users, OEM’s and rebuilders in this industry.
