Also called double-lip U-cups and lip seals, they have nitrile lips and a urethane base to provide good stability and support large loads. Vee Packs: These are seals designed with multiple vee rings. The negative lip forms of normal seals allow dirt and foreign particles to be trapped between the seal lips and the cylinder. Sealing materials designed for life science and medical applications must demonstrate excellent resistance to the aggressive organic and inorganic chemicals and media associated with surgical and laboratorial procedures, including intensive cleaning regimes. We supply Hydraulic & Pneumatic seals for single and double acting cylinders, composite piston seals, compact seals, independent wear rings, bonded seals, static seals ( Rings), and symmetrical seals. Rod seals are key in preventing corrosion. A static hydraulic seal is located in a groove and sees no movement – only sealing within its confined space, acting like a gasket To achieve this the gasket should be under pressure. The material we choose for each hydraulic seal is determined by the operating requirements of each application. Style WK Rod Wipers Double lip design provides the ultimate in wiper action to remove foreign material from the exposed rod while still maintaining an adequate lubricating film. Scrapers & Wipers – Scrapers and wipers are components which prevent the build up of dirt, foreign particles and moisture from the piston rods by scraping or wiping it away. Rod seal kits include a rod assembly, rod wiper seal, U-cup rod seal, and -ring for repairing hydraulic cylinders. A hydraulic seal, at the end of the day, must prevent leakage of fluids from cylinders. Other products offered are mechanical, magnetic, non-contacting, and lip seals. Wear bands or wear rings are used to prevent metal-to-metal contact. Seals are divided into three main classes: packings, gaskets, and wipers. V-ring packings (AN6225) are one-way seals and are always installed with the open end of the V facing the pressure. Sometimes however you can use two single acting seals in a ‘back to back’ arrangement in order to create a double acting seal system. This seal is recommended when the coupling clearance between the head and the rod cannot be reduced and in the event of pressure peaks (500 bar). Hydraulic seals are also subdivided into seals, which have symmetrical or asymmetric cross-sections. Piston seal is a type of hydraulic seal where the sealing lip has contact with the entire housing bore. Quad rings can be used in both static and dynamic sealing applications. Rod Seal failure could result in fluid leakage. Rod Seals are affected by changes to the rod surface and fluid temperatures. Suitable for hydraulic applications that anticipate abrasive contaminations and shock loads.
High pressure, medium used, extreme temperatures, aggressive chemicals, working environment and legislation standards will all have an impact on the chosen material of seal. A hydraulic sealing product is actually a family of products used to seal reciprocating, oscillating or slow rotational movements caused by hydraulic equipment. As system pressure increases, the -ring is energized and forces the lips outward, changing its behavior from a squeeze type seal, to a traditional leap seal. Imperfect mating parts require some type of sealing device to be inserted between them to seal against loss of liquid, gas or solid fluids or particles. Chesterton’s broad range of high-performance hydraulic seals are made from exclusive polymer materials for use in a wide range of demanding industrial sealing applications. Over four million seals in a variety of case and lip styles. PTFE is the chemically inert of the -ring materials. Wear Rings are guiding elements that snap onto a shaft, both piston and rod, to keep metal from contacting metal that will damage and score the surface of a cylinder.

For designs of medium to high pressure, it is recommended that fabric reinforced -rings be utilized. Piston seals are used in both pneumatic and hydraulic seals. The wiper seal needs to fit both the rod (dynamic) and also to the housing (static). Piston seals specifically work by preventing leakage or fluid flow across the piston. HydraPak stocks a substantial selection of hydraulic and pneumatic seals. Daemar’s line up of hydraulic seal products has been developed to provide exceptional value by combining the quality and performance that design engineers require with the total cost of ownership savings that today’s businesses demand. Wear rings or guide bands serve no sealing function. Shaft seals are tools that help to prevent the contamination of hydraulic shafts. 10. Wear-resistant: Typical hydraulic seals are wear-resistant and thus can be used in mining and extraction of minerals. When pressure is applied, it tends to force the -ring across the groove, causing the ring to further deform and flow up to the fluid passage and seal it against leakage. The U-ring and U-cup seals pressure in only one direction; therefore, the lip of the packings must face toward the pressure. These Parker seals and Parker -rings are offered in a variety of materials and lip geometries for the best possible solution for a given application. Hydraulic Rod seals prevent leakage of fluid from within the cylinder to the outside while hydraulic piston seals prevent fluid from flowing across the cylinder head. Misapplication or use of non-compatible materials can lead to chemical attack by fluid additives, hydrolysis and oxidation reduction of seal elements. They prevent the leakage of fluid from within a hydraulic cylinder to the outside as the rod cycles back and forth (dynamic pressure sealing). Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. Whether you’re looking for standard sizes or need a full set of custom hydraulic seals, we have the ability to provide any shaft seal type with our cutting-edge machining services. WDA Wiper Seals: These double-function seals use the lip to prevent contaminants from building up, yet also have an additional element that prevents scoring on a seal.

This reduction in squeeze means less friction and improved seal life, and because parting lines are between the lobes, away from the sealing surface, problems of leakage associated with -rings is virtually eliminated. WRB Wiper Seals: These Medium Duty scraper seals have a special lip that help prevent moisture and dirt from accumulating on the rod. If the clearance gap between the sealing surface and the groove corners is too large or if the pressure exceeds the deformation limits of the -ring material (compound) , the -ring will extrude into the clearance gap, reducing the effective life of the seal. Manufacturer of standard and custom hydraulic seals. GUARNITEC use very high quality polyurethane compounds and other materials in their production. Many hydraulic seal suppliers have the same exact seals that are used in most hydraulic cylinders and can easily cross reference or match up a replacement. When the wiper seals are not secured or fail, it can cause component failure in a fluid power system that leaves other pieces of the operation open to serious damage. For heavy-duty hydraulic cylinders. You’ve discovered -Rings, Inc. Despite the greatest of care, conventional seals are highly vulnerable to damage of the sensitive sealing faces during installation. 3. Leakage control: The use of hydraulic seals can prevent any leakage, thus reducing any chances of downtime or repair. The specific operations of a hydraulic seal differ slightly depending on where the seal is located with regard to the hydraulic cylinder. Hydraulic seals should be a fairly high priority for checkups by your maintenance team. T-seals are composed of a sealing element with two split back-up rings. Industries hydraulic seals serve include aerospace manufacturing, agriculture, automotive manufacturing, chemical processing, defense contracting, food processing, marine products manufacturing, medical and pharmaceutical products development, nuclear power, pulp and paper, and waste disposal. Rods seals, piston seals, wipers, guiding rings and statics seals on stock. Rod Seals: These hydraulic seals are used to prevent fluid leakage within cylinder. Static seals that installed directly into the housing or glands of a system, rod seals are designed to provide dynamic sealing pressure while the piston rod is in dynamic motion. The external lip scrapes foreign matter from the rod, and the other lips act as an effective pressure seal in low pressure applications. Furthermore, purchasers of hydraulic seals should take note of vacuum rating, working temperatures, chemical compatibility (between the seal and the hydraulic fluid), highest and lowest working speed, and minimum and maximum pressure. Because System Seals specializes in custom designs and sizes, the company is a perfect fit for the cylinder repair industry, and it continues to save its customers millions of dollars each year. Asymmetrical seals are so designed that in the installed state they contact the static surface with an initial stress over the whole axial width in order to achieve a sufficiently firm seating in the groove. Wipers are designed to prevent any contamination to the system by external media during stroke movement of the cylinder. We will work with you to ensure our rod seal designs meet your application requirements. U-ring packings (AN6226) and U-cup packings are used in brake assemblies and brake master cylinders. FKM – When applications that require better chemical resistance and higher temperatures up to 400°F (FKM seal elements) with two PTFE or PEEK back-ups are recommended. Hydraulic rod seals are installed in a groove that has been machined in the cylinder housing to provide a tight seal against the piston shaft. These anti-extrusion rings are available in various extrusion-resistant materials and are located on the back-side or low pressure side of the sealing element they are supporting.
