A hydraulic system is only as capable as the fluid conveyance technologies it consists of. Among the most important components of any hydraulic system are the seals, wipers and O-rings that contain the fluid. Given the pressure and temperature extremes that the systems experience, utilizing the right kind of material for sealing can be the difference between years of successful operation and frequent failures and breakdowns.
One of the most significant advances in fluid conveyance technologies is Parker's Resilon® 4300 polyurethane. Based on PPDI (p-phenylenediisocyanate) chemistry, Resilon is a thermoplastic polyurethane that is in some ways similar to other PPDIs. However, its performance represents a combination of the best characteristics of many different compounds, all combined into a single polyurethane:
All of these technical benefits mean that, for extreme applications, Resilon is the only suitable choice. In less demanding applications, Resilon seals and o-rings still have longer service lives than components made of alternate materials. They also resist extrusion and can be set under compression while still maintaining contact to keep seals intact.
Resilon 4300 polyurethane is utilized for a range of products in many standard sizes and shapes, such as o-ring and wiper formats, to fit most applications. Parker also offers D-rings made of Resilon 4300 polyurethane. This shape offers the performance of a traditional multi-component seal but with longer life. In addition, its unique shape makes it easier to install and reduces the risk that the seal will be cut or otherwise damaged as a part of the installation process.
