Thank you for your question.
The ABB01 is a 1/8 IPS female-threaded ball armback, and the PIAL48 is a 48-inch long 1/8 IPS threaded pipe stem with male threads on both ends.
Since 1/8 IPS male threads are designed to thread into 1/8 IPS female threads, the PIAL48 stem is compatible with the ABB01 and will thread directly into it.
For a better understanding of lamp thread sizes and IPS threading standards, please refer to our help desk article:
