Welcome to JOF. Is it a rubber liner connected to the “t” connector that’s leaking? If so, head to the local auto parts store for a couple small 1/4” hose clamps. Cut the hose off the “t” and replace it using the hose clamp in place of the PEX clamp originally used. The old PEX clamp will take a bit of effort to loosen and remove but it cam be done by wedging a small screw driver into the opening and twisting to open further. If it’s a PEX line clamp leaking, you can use a ceramic tile nipper tool to close the tighter.
