Hydril Pressure Control GX* Annular BOP
Drilling contractors have called the Hydril Pressure Control GX*, "the best darn annular in the business" for one reason: exceptional uptime. Its single packing unit has provided continuous service for as long as a year, and it has continued to hold pressure after exposure to extreme temperatures and extensive stripping.
