These stainless ball lock posts fit the gas (in) side of old Cornelius brand kegs, as well as newer A.E.B. Italian-made kegs, Chinese Kegs, and Italian-made Spartanburg VI Kegs that have a number (P/N) stamped on the front ending in PS. These have the same threading as Cornelius plugs, 19/32-18.
Note these do not include needed Universal Poppets (our item L92) or needed Ball Lock O Rings (item D12). You will need one L92 and one D12 in addition to this post to complete your male in gas fitting. These do not accept the Cornelius specific poppet (our item D85) are designed to fit the universal poppet valve L92.
