SST: Subsea Stud Tensioner

SST STUD TENSIONER

Product Type: SUBSEA
Features quick reaction nut, visible piston stroke indication and anti-slip cylinder surface for improved handling.

‘D’ includes an allowance for tool removal after bolt tightening with 30mm tool stroke
Product development is constantly taking place and dimensions may change without notice

SST: Subsea Stud Tensioner Our incorporating the quick reaction nut feature reduces diver fatigue, improving diver safety and productivity.
