(Hi-Well ® is a registered trade mark)

 

U series of the nitrogen gas springs are the super force type. Because has used the piston seal structure, they can therefore provide in the smaller space, express ultra formidable strength and may cause the mold volume more reduction. This type can be used independently, also can be joined with many pieces to compose the system. Their strength also can be adjusted by a system. This product widely applies in the metal stamping, formation, automobile manufacture, injection mold, mechanical device.

If to use them in a hose system, please mark the “- G ” after the model number when to place an order.
