Design
The HET series of standard external tensioners is a light weight, compact and versatile line of tensioners. The HET bolt tensioner series operates at a maximum pressure of 20,000 psi and utilizes high strength AISI 4340 steel components for long lasting performance unless distorted. The HET series was designed with the aid of 3-D solid modeling and finite element analysis.

Features
The HET series of standard external tensioners is a modular design which provides the widest range of flexibility possible. Different stud sizes can be accommodated by simply changing the Puller Screw, Bridge and Socket, while utilizing the same Load Cell. The Load Cell is provided with either one or two quick disconnects nipples to allow fast and easy connections. Whether simply connecting to the oil supply or connecting multiple tensioners in series, the HET is fast and user friendly. All exterior surfaces are knurled to allow for easy handling and larger sizes include eye bolts for additional support.
