yes same thing happen to me, and since I am stubborn I try every brand seal available, that was about 7 times had to change that seal, guess what nothing worked eventually they all leaked few weeks later. Now the solution, just take the spring from another same size seal and overlapped over the spring on the seal your going to install. that solved for me, finally no more leak. I think that finally installed one from oringsandmore that had the highest psi rating over others they sell. that one has the strongest spring, then overlapped a weaker spring from other of the sames size seals I had bought. hasn't leak since that.
