ProTeam Twist Cap Gasket Super Coach P620B and a failing left-hand blockThis twist cap gasket (part #104998) is a compatible replacement seal for the ProTeam Super Coach and MegaVac 10 qt. backpack vacuums. The gasket sits under the twist cap and keeps that connection airtight. A gasket that has flattened or hardened lets air leak past the cap, and even a small leak here bleeds off suction at the cleaning head. Swapping in a fresh gasket is an inexpensive fix that brings suction back to full. Fits: ProTeam Super Coach and
