This fully enclosed, air-powered grip is ideal for seal strength testing of packaging, elongation testing of various materials, and other tensile testing requirements, per ASTM F88 / D1876. Serrated interlocking jaws effectively grip samples for up to 100 lbF (500 N) of force.The grip features an industry-unique integrated open/close valve for quick sample engagement and disengagement, an added benefit for repetitive applications. An air connection kit, consisting of air tubing and fittings, is available as an option. Use a pair of these pneumatic grips with a force gauge and a test stand to create a complete testing system.
