What Parker Hannifin makes for data centers
public · HQ Cleveland, United States · parker.com
Parker Hannifin makes quick-disconnect couplings for liquid-cooled racks under its UQD and blind-mate UQDB lines, which follow the Open Compute Project's UQD specification, as well as hoses, fittings and filtration used in coolant loops. Data-center liquid cooling is a narrow slice of its broader motion-and-control portfolio.

Where Parker Hannifin sits in the stack
Parker Hannifin's placements in this catalog cover 5 parts, from layer 5 (liquid cooling (it-side: chip to cdu)) to layer 6 (facility cooling & hvac). None of them currently carries a sourced supply constraint tag. Across these parts it overlaps with other companies most often on the lines below.
What these parts are
- Rack manifolds — The manifold (sometimes called a CDM) that distributes coolant from the CDU supply line to each cold plate in a rack and collects the return flow, usually mounted vertically at the rear or side of the rack.
- Quick disconnects — Blind-mate connectors (UQD or UQDB) that let a compute tray or cold plate be connected to or disconnected from the coolant manifold without draining or spilling the loop.
- Hoses, tubing, fittings, valves — The flexible hoses, rigid tubing, compression and push-fit fittings, and shutoff or balancing valves that carry coolant between manifolds, quick disconnects, and the CDU.
- Filtration — Filtration inside or ahead of the CDU that removes particulates from the technology-side coolant loop before it reaches the narrow channels of manifolds and cold plates.
- Air handling, economizers, filtration — Air-handling units, outside-air economizers, and filtration equipment that condition and clean the air supplied to air-cooled data center halls.
