Pneumatic strapping tool STS 25 & 32 PLUS 4

for steel straps

Product overview
Pneumatic strapping tool for steel strap designed for heavy-duty industrial applications and low-pressure air systems. The updated design features a smaller, reinforced and lighter body compared with the previous HT model, enabling reliable operation from 4.5 bar while maintaining superior seal notch integrity. The reduced size and weight improve handling and ergonomics for continuous use. The lower-pressure function (from 4.5 bar) is available for both 25 mm and 32 mm steel strap.
