Compact Shear & Seal – CSS

south

CSS Overview

Unity’s innovative CSS forms an integral part of our advanced pressure control offering offering. It provides a safe and reliable shear and seal mechanism for our Surface Intervention System rods, coiled tubing, slickline and wireline. Its ultra-compact form reduces heavy lifting, access hatch restrictions and stack-up height, significantly improving operational safety.

The industry standard shear and seal method provides high shear load capacity, easy maintenance and ram replacement, and reliable performance.
