Safe, reliable and repeatable, the use of hydraulic tensioners
offers many advantages over other less accurate tightening
methods. Hydratight’s Aquajack ® subsea tensioners
allow divers to perform the tensioning process with tools
designed specifically for their unique requirements.

Easily positioned in poor visibility conditions, Aquajack ®
tensioners feature a compact design and long piston
stroke. The unique Split Nut ® design of these tools
allows rapid application to long bolts and damaged
threads, and rapid tool removal.
