PRY‑type piston rod seal is an asymmetric single‑acting rod seal specially developed for hydraulic cylinder rod applications. Optimized Y‑shaped cross‑section provides excellent pressure resistance and wear resistance. It maintains stable sealing performance under high‑pressure, heavy‑load and long‑reciprocating‑cycle working conditions, effectively reduces hydraulic oil leakage. Mainly made of high‑strength polyurethane, fits standard seal grooves for easy installation, widely used in construction machinery, hydraulic equipment and industrial cylinders。
