Steel Pneumatic Strapping Sealers

Pneumatic sealers let compressed air do most of the work. They are used to achieve high production on heavy strapping, especially when seals are in awkward positions or whenever productivity must be maximized.

Steel Pneumatic Strapping Sealers come in two basic styles:

Pistol Grips - lightweight for easy one-hand operation
Diaphragm Types - for heavy duty applications

Snap-on seals - placed over the overlapping strap ends either during or after tensioning. Eliminates pre-threading.
Thread-on seals - must be threaded over the overlapping strap ends before tensioning tool is applied. Generally used on bales, bundles and the larger strap sizes.
Open-flange seals - heavy duty version of the snap-on. Requires no pre-threading.
Push-type seal - used where strap is tensioned by butting the nose of the tensioner against the seal. Overlapping flanges withstand the higher stress.
Nestack® seals - held together by interlocking nibs. This Signode development permits loading partial stacks into magazines of seal feed combination tools and power strapping machines.
