High Temperature Nuts

Hydraulic Nuts For High Temperature

Hydraulic tensioning with hydraulic tensioners and nuts is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical fasteners. At HTI, we’ve been building hydraulic tensioners and nuts since 1986. 

HTI’s standard hydraulic nuts are suitable for most applications. We also provide hydraulic nuts suitable for high-temperature applications. High-temperature hydraulic nuts require a different seal than standard hydraulic nuts.

  • HTI standard hydraulic nuts are rated for continuous operation in temperatures up to 200°F (95°C)
  • HTI high-temperature hydraulic nuts are rated for continuous operation in temperatures up to 250°F (120°C)
