Types of Hydraulic Seals The most commonly used material is acrylonitrile or nitrile butadiene rubber (NBR). If using wear rings, please consult Engineering Section (Section 2) of Parker's Fluid Power Seal Design Guide, Catalog EPS5370. 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. Rod seals are radial seals. There are also a variety of variants, including the use of bronze coated with polytetrafluoroethylene, and so on. When seals harden, they crack and lose elasticity, leading to seal failure. Hydraulic Seals. Applications: Polyurethane oil seals are used in high-stress hydraulic applications, in which highly pressured compounds are exposed to wear. Durability and fit are key, so you need to purchase these seals from a reliable distributor. Standard product orders take about a week to deliver and custom product orders take slightly longer (about four to six weeks). Results of physical and chemical reactions: Discoloration of the seal material Swelling (change in seal material volume - increase) Shrinking (change in seal material volume - decrease) Duralast materials are specially formulated elastomers developed to offer targeted media compatibility, high functionability in extreme operating conditions, or simply extend service life of critical equipment, all while maintaining the excellent flexibility and ductile properties that make elastomers such good sealing materials. Seal material particularly resistant to abrasion and extrusion. Hydraulic sealing solutions for fluid power applications have become a priority in our continued product offering.
