Product Introduction

Description

The Double Delta Hydraulic Piston Seal is a double-acting low-friction piston seal for tiny o-ring grooves that expands the service range beyond what one o-ring alone can support. It's made for light-duty use and is especially well-suited to small-diameter installations. The high-performance materials offer excellent wear and extrusion resistance, as well as a wide temperature and medium compatibility range. Furthermore, Hydraulic Piston Seals Double Delta gives great dry running and stick-slip-free startup. In the thin, flexible middle region, it preloads the seal cap. Even at low pressures, this provides good leakage control.
