Pentax ring adapter sizes

I recently purchased a Pentax af160 ring flash.
Im sure your aware, included in the pack were 4 adapters to mount the flash on the lens.
I have one lens with a 55mm filter size and there is no adapter that size in the kit.
Do Pentax make additional adapter sizes such as 55mm?......its a Sigma lens that came with the ISDs.
Could you advise on availability and approx cost

Pentax does not make a 55mm ring. This adapter enables a lens accessory with an attachment size of 58mm to be used with a lens with an attachment size of 55mm.
