You need to use imperial to metric compressions.
Not with 15mm. ½" imperial is only very slightly bigger and will fit inside a 15mm olive. ¾" imperial is however significantly smaller (0.5mm) than 22mm, so the gap is too big to be reliably taken up by compressing the 22mm olive. Fitting a ¾" olive instead is the simplest solution.
