ZSPEC represents the future: a better way of doing business.

Our founder, Steve Chin, created ZSPEC after spending 16 years working in the oil and gas industry. He witnessed the slowdowns that happen when too much time is spent having to search for the right valve or fitting.

ZSPEC, has ready to ship inventory from all MPI Warehouse locations and Houston. We have the ZSPEC item you need, when you need it.

ZSPEC supplies top-quality valves and fittings. Like MPI, ZSPEC is guided by a singular determination to do whatever it takes to be a reliable supplier for our customers.
