Replacement Kit Includes: (2) 2.7mm wide heating element, (2) 1/2" PTFE adhesive, 1ft. long roll of PTFE cover, and (1) blade. Choose the replacement kit that is compatible with WN-900C
We recommend replacing the bottom PTFE adhesive strip (1/2" wide sticky backed-remove the liner) every time the element is replaced. Place the PTFE adhesive strip under the element on the base of sealer.
