Tensioners - Topside

The Tensioners - Topside offer an integrated solution for piping problems with a coverage range from 3/4” to 4” bolt diameters using just 8 tools. These spring return bolt tensioners are designed to dramatically increase productivity and safety on the job site compared to older manual return tensioners. They feature piston overstroke prevention, piston stroke indication, and are compatible with the MRT Tensioner range. The unique quick-release bridge adaptation and piston/cylinder misalignment compensation ensure reliable and trouble-free operation. The fully enclosed load cell design eliminates debris entry, enhancing durability and performance. Designed to fit BS1560 / ANSI B16.5 / API flanges, these tensioners are perfect for various industrial applications.
