Designed to test the pull and push force of springs, insert these testers into your quality control line right out of the box. Unlike force gauges, they measure both the compression and extension distance of the spring. Use the display to set your upper and lower limits. A green light means the spring is good to go. If it’s not, you’ll hear an alarm and see a red light. Activate the peak-hold setting to keep the highest reading on the display. With the automatic release, you can prevent the tester from applying force after it has recorded a peak. The built-in printer makes it easy to print results.

Stainless steel construction provides corrosion resistance for use in damp environments. These gas springs have a ball socket end fitting and ball stud on each end for mounting. Ball socket end fittings rotate in any direction on the ball stud to compensate for misalignment.

These gas springs have a bleed valve so you can release gas to permanently reduce the force to meet your requirements. They come charged to their maximum force. Use the included tool to open the valve and bleed off the gas—there's no disassembly required. Release gas in very small increments and then test your application. Once gas is released, the force is permanently reduced. Gas springs have an eyelet end fitting on each end; requires an eyelet mounting bracket (sold separately) for mounting.

Rod Protectors—Rod protectors (sold separately) prevent impact damage.

Mount one end to the frame and the other end to the door to prevent it from opening too far.

These gas springs have threaded ends so you can use them with any combination of end fittings, studs, and mounting brackets. Select end fittings with a thread size that matches the rod and end thread sizes of your gas spring.
