LTK-T Push-Pull Fluid Connectors for Liquid Cooling, to +175 °C
Push-pull bayonet · double seal · 20 bar · −55 to +175 °C
Liquid-Cooling Fluid Connectors
Push-pull bayonet fluid connectors that connect liquid-cooling modules and pipework in rugged electronics, with double seals and low spillage.
Liquid-cooled electronics need fluid connectors that couple with one hand, seal while connecting and disconnecting, and keep pressure drop low.
LTK-T connectors (−55 to +175 °C, nickel-fluorocarbon finish) and TSA connectors (anodized aluminum or stainless steel, 1000 mating cycles) cover bores from 3 to 20 mm, 20 bar working pressure and flows up to 94 L/min. Both are shock and vibration tested with pressurized fluid.
Compare series
| Series | Bore | Max. pressure | Max. flow | Temperature | Mating cycles |
|---|---|---|---|---|---|
| LTK-T | 3 to 16 mm | 20 bar | 2–60 L/min | −55 to +175 °C | 500 |
| TSA | 3 to 20 mm | 20 bar | 2–94.2 L/min | −55 to +95 °C (FVMQ to +155 °C) | 1000 |
