U-Seal, 1-1/4"X1-1/2"X0.19"

U-Seal, 1-1/4"X1.491"X0.19"

The RTU12-1.25-19 U-Seal is a high-performance twin-lip rod seal designed to handle demanding hydraulic applications with lower friction, increased stability, and strong dynamic sealing force. Its twin lip design helps prevent air intrusion from outside the cylinder while maintaining consistent sealing under pressure. Manufactured from durable 94A urethane, this seal is built to perform in high-pressure systems while keeping wear and drag under control—because leaks belong in plumbing, not hydraulics.
