The legendary first-generation Air Leak Viewer, the "MK-750," will unfortunately cease production as of June 30, 2023 (Friday). Therefore, starting in July 2023, we will offer it at a clearance price. Although it is an older model, it has the same applications and equivalent performance as the current new model "MK-750ST," and we believe it can meet your needs. For more details, please refer to the related products and catalogs.
