Replacement SPX's SRT Bolt Tensioners

The Spring Return design dramatically increases productivity and safety on the job site when compared to older technology manual return tensioners.

• Piston overstroke prevention

• Piston stroke indication

• Compatible with MRT Tensioner range

• Unique quick-release bridge adaptation

• Piston/cylinder misalignment compensation

• Bolt coverage from 20 to 115 mm (3/4" to 4") with just 8 tools

• Designed to fit BS1560/ANSI B16.5/API flanges

• Fully enclosed load cell design eliminates the entry of debris into the piston retraction mechanism

• Piston over-stroke eliminator to prevent over-stroking and blowing a seal

• Twin hydraulic couplings for multiple tool connections

• Requires stud to protrude above nut by 1 x bolt diameter

• Application-specific tooling available. Contact factory for details.
