Manually-operated sealers for steel strapping are used for low-volume applications or where access to an external power source is limited. They can be carried to the work location. The operator squeezes a lever to crimp and press the seal in place.

Pneumatic sealers for steel strapping, also called air-powered sealers, connect to a compressed air system to automatically apply seals to steel strapping in medium-to-high volume applications. Strapping is used to bundle and secure items together for shipment and storage. They can be used on flat and round surfaces, such as pallets and pipe, and are compatible with all seal sizes and strapping strengths.

Battery-powered sealers for steel strapping have a rechargeable battery that allows the tool to be easily moved around a worksite, and reduces hand fatigue that can be encountered when using manually-operated sealers. They do not require attachments, can be used on flat or round surfaces, and are compatible with all seal sizes and strapping strengths.
