A machine shop
that ships product
Rigid Hardware is a product line of Rigid Concepts, LLC, a precision CNC machine shop in Van Alstyne, Texas. We make parts on our own machining and turning centers and have spent years cutting 316 stainless for customers who reject parts over half a thousandth. Turned-and-milled stainless work is what this shop was built on.
We started making data center liquid cooling hardware because we watched the direct-to-chip buildout stall on the small stuff. Commissioning teams with racks staged and CDUs on the pad were waiting 12-plus weeks for a stainless adapter or a manifold fitting, then paying panic pricing to expedite it. These are parts we can machine in an afternoon. So we built a standard line around the ORV3 and OCP ecosystem, UQD and UQDB interfaces, and PG25 loop hardware, and we keep it moving.
Everything ships from the same building in Van Alstyne where it was machined, passivated, pressure tested, and bagged. No import lead times, no broker markups. When you call about an order, you are talking to the shop that cut it.
Every part is inspected by a machinist before it's bagged, not sampled by a percentage. If anything we ship doesn't meet print, we replace it or refund it.
