A head seal is a durable, static seal designed to replace the O-ring and its back-up at the top of a hydraulic cylinder. Its symmetrical one-piece construction addresses two specific failures common in cylinder heads with high misalignments or large extrusion gaps: O-ring back-up 'blowout' and pinched back-ups. These advantages stem from its unitary design, which reduces the potential for damage during installation and simplifies the installation process. Made from durable materials, the head seal provides exceptional resistance to wear, temperature fluctuations, and chemical corrosion. Ideal for automotive, aerospace, and industrial applications, the head seal ensures reliable, leak-proof performance while minimizing maintenance requirements and enhancing the overall efficiency of hydraulic systems.
