STS 25 & 32 PLUS 4

Pneumatic Strapping Tool for Steel Strap with Seal

It is a powerful and reliable strapping tool. It is designed to use in heavy duty industrial applications, particularly in low pressure air plants. Thanks to the new design (smaller, reinforced and lighter body compared with the previous HT model), the tool can work perfectly even with low air pressure (from 4.5 bars) and can offer a constant and superior seal notch integrity. The body is smaller and lighter than the previous STSR 32 HT allowing for easier handling. The lower air pressure function (from 4.5 bar) is also available for 25 mm steel strap.
