Piston Seal 659 "Hallite"
Twin lip, asymmetric single-acting piston seals provide a dry sealing solution through precisely trimmed sealing lips.
Hallite 659 is designed to interfere with the piston seal groove diameter and features a secondary lip. The secondary seal lip, positioned behind the primary seal lip, enhances the stability of the seal within the piston. The outer dynamic lip is shorter and is designed more robustly to improve sealing performance and compression set characteristics compared to conventional symmetrical U-rings. The 659 is molded from Hallite's high-performance polyurethane, Hythane 181, making it easy to install and providing excellent low-temperature performance. 【Features】 ■ Robust design ■ Excellent wear resistance ■ Improved seal stability ■ Functions properly over a wide temperature range, highly effective even at low temperatures ■ Protection of the primary seal lip ■ Easy assembly Hallite is a group company of Michelin. *For more details, please refer to the PDF document or feel free to contact us.
