Typically, a 3/8 IPS threaded pipe measures approximately 5/8in outside diameter. Tubing with an inside diameter larger than 5/8in should slip over it.
Thanks for the question! For a better understanding of lamp thread sizes and their actual outside diameters, please refer to our Thread Size Chart.
Something like TU0-34SM would work and leave you a little extra room if needed.
