Is is possible to order the G1/2" (British Standard Pipe Parallel Thread (BSPP)) variant of this sold overseas? Caleffi part number 508041. My issue is that I have already bought, installed, and begun to utilize my European made radiators that utilize G1/2" (BSPP) threads and I would love to utilize this hygroscopic vent for my high point radiators. However, as you can imagine, it is difficult to convert BSPP to NPT - or find another comparable air eliminator/vent. My other question would be that if I am able to solidify the G1/2" BSPP variant of this vent, are the hygroscopic discs interchangeable between the 1/8" NPT model sold here in North America and the G1/2" BSPP variant sold in Europe?
