TSA Bayonet Fluid Connectors for Liquid Cooling, 3 to 20 mm
Bayonet · 3–20 mm bores · 1000 cycles · low spillage
LTK-T Push-Pull Fluid Connectors for Liquid Cooling, to +175 °C
Push-pull bayonet · double seal · 20 bar · −55 to +175 °C
LTK-T fluid connectors connect and disconnect liquid-cooling modules and pipework with one hand. A bayonet push-pull lock and a double seal keep the joint tight during mating and unmating. The aluminum body has the wear-resistant nickel-fluorocarbon (T) finish, and the optimized flow path keeps pressure drop low.

Frequently asked questions
Does LTK-T leak when disconnected?
LTK-T uses a double seal that keeps the joint sealed during connection and disconnection. Tell us your fluid and allowed spillage and we will confirm the configuration.
