H-Style Wiper

Overview

This versatile rod wiper, featuring a one-piece snap-in design, is ideal for light-duty tasks and also functions as a secondary rod seal. The innovative U-Cup lip not only minimizes visible rod seal leakage but also maintains robust ingression resistance comparable to sharp lip wipers. Additionally, its easy installation and reliable performance make it a top choice for various applications.
