Replacement Seal Pad for the VacMaster® VP112 Series Chamber Vacuum Sealers. The seal pad will press the vacuum packaging bag against the seal bar, which completely forms around the sealing wiring creating a tight seal on the bag. Overtime the seal pad may show signs of wearing, keep a replacement handy so your vacuum packaging process never slows down. Easy installation. Direct replacement part, compatible with VacMaster VP112 and VP112S.
