Wedges For Series 647 Hydraulic Wedge Grips
Wedges for Series 647 Wedge Grips come in a variety of surfaces to meet requirements. They employ a unique wedge design that significantly reduces the stress concentration on the specimen, enabling even very brittle composites to be gripped securely without grip-induced failure.

Full Product Information
Wedges for Series 647 Wedge Grips come in a variety of surfaces to meet requirements. They employ a unique wedge design that significantly reduces the stress concentration on the specimen, enabling even very brittle composites to be gripped securely without grip-induced failure.
MTS 647 Wedges can be ordered with a water-cooled option. These wedges are used with a Water Cooling Kit that is purchased separately.
Model 647 All-Temperature Wedges are available for the all-temperature grips. Contact MTS for additional information.
Water Cooling Kit
There are two versions of the Water Cooling Kit. Both versions include hoses, fittings, metering valves and a manifold that attaches magnetically to your load frame or other flat, steel surface. One version also includes water flow switches. Some MTS products, such as the Model 653 furnace, support integration with the flow switches, enabling protection of the equipment in the event of a water supply failure. Please check with an MTS Applications Engineer to determine if your equipment is compatible with the flow switch protection circuit.
