L190H insert is a Hytrel jaw-coupling insert with fair flexibility and hard torsional stiffness. L190H inserts are also called L190H spiders and are used within L190 coupling hubs. The insert is the critical component allowing flexibility and is placed between the jaw hubs, preventing metal-on-metal contact. More specifically, the L190H coupling insert is made from high-quality Hytrel, which is a thermoplastic polyester elastomer material that is white in color. The material can operate in temperatures ranging from -60F to +250F and has excellent oil and chemical resistance; for more information on jaw coupling inserts, visit our main Jaw Coupling page or contact our customer support team.
