Spring Return Hydraulic Stud Tensioners
The MTT SPX SRT Spring Return Hydraulic Stud Tensioners are the quickest and most efficient stud tensioners available. Our hydraulic stud tensioners include a spring return load cell to expedite ram retraction. The SPX SRT’s are lighter in weight and offer a host of safety and fail-safe features such as the safety relief valve to eliminate over stroking the ram and having to change the seal.
