0707 Gasket Replacement Kit – Fits Motive 1108 & 1118 Adapters

The Motive Products 0707 gasket replacement kit restores the sealing surface on the 1108 and 1118 GM brake bleeder adapters. These adapters cover late-model GM trucks, SUVs, and performance vehicles with the three-tab round master-cylinder cap — keeping the seal fresh means consistent 15–20 psi bleeding pressure every time.
