A low-leakage seal system for a pivot door type thrust reverser comprises a forward seal, an aft seal, and a pair of seal stops. The forward seal is attached to a forward portion of a thrust reverser. The aft seal is attached to an aft portion of the pivot door. The seal stops are attached to opposing sides of the pivot door and each seal stop couples with a pivot door hinge pin. Each seal stop includes a forward tab and an aft tab. The forward tabs of the seal stops make flush contact with the forward seal and the aft tabs make flush contact with the aft seal such that a continuous seal is formed between the pivot door and the fixed structure of the thrust reverser when the pivot door is stowed.
