Why is there a small gap between my Clik core and valve stem?

A small visible gap can occur because valve stems differ slightly in how their internal threads position the core. The seal forms inside the stem, so a flush-looking outer joint is not the test for correct sealing.

If the valve holds air, a small gap can be normal. If it leaks or the fit looks unusual, contact us with the stem model and a close-up photo so we can check it. Do not treat a leak as normal just because a gap can be acceptable.
