This elegant PCIE Slot Cover with Fill Port equips with an automatically closing tube connection to the outside of the computer. This connection has a valve that only opens when a tube is inserted and closes again when removed. On the inside, a G1/4 thread is available for connection to the cooling circuit. In a liquid cooling system equipped with LEAKSHIELD, coolant refills are very easy. After activating the filling mode on the LEAKSHIELD, the tube plugs in while the free tube end holds in the coolant bottle/canister. The coolant is sucked into the cooling system by negative pressure. After reaching the desired level, the tube is pulled out of the coolant bottle/canister again, the remaining amount of liquid still contained in the tube also sucks in. The tube then disconnects from the slot cover, which locks the connection again. Scope of delivery: A stainless steel slot cover Acetal feedthrough and automatically closing tube connection Two meters suitable filling tube Please note: Internal connection for connection to the cooling system is not included in the scope of delivery, please order a connection suitable for your tube system separately. **LEAKSHIELD not included.** Model: 34143
