@SidTheKing If it is not the same SMC part number, then it is not identical. The SMC fitting is available from a variety of sources, for example, MSC has them here: http://www.mscdirect.com/product/details/51433498?rItem=51433498
Zoro has them at a good price as well (and free shipping over $50): Smc Union Tee, 5/32 in., TubexTube KQ2T03-00A | Zoro
Robotics is very concerned with safety, especially with pneumatics, which is why “identical” is required in this case, even if the alternate is fully functional. It makes the inspectors job easier, too.
