Drilling & Completions

When you own a

Since 1968 and take the recommendation of ASME, DIN, ISO and

EN into consideration to place a washer underneath the nut to eliminate galling and great frictional variation… here is what your hytorC will do for you: * Supreme Safety: You fnally operate your HYTORC without a hazardous reaction arm and backup wrench and without holding the tool on vertical or inverted applications * Top Joint Reliability: You avoid joint-failure and leakage with precise and even, circumferential joint compression, which we guaranty * Top Tool Reliability: You drastically improve your

HYTORC’s longevity and warranty * Always on Time: You cut the number of passes in half to avoid delayed startups * Better Handling: You simplify tool handling to reduce human error

Being # 1… is no coincidence!
