Hello,
So looking for a cheaper alternative to the SMC Tee-Fitting offered by VEX, I found this Link: goo.gl/j0CnTZ, does this Tee-Fitting count as an identical part. It has the same specs as the SMC Tee-Fitting if not better ratings.
No, since this part is different than the one that’s part of the VEX EDR product line, it is not considered identical, thus it is not legal.
