Black quick-release coupling set with two G1/4 male threads and lock nuts for bulkhead mounting

Alphacool

Alphacool ES Quick Release Coupling Set IT/IT Black 17598

SKU CH-YD8S-FMMSM

Quick-release bulkhead fitting set for permanent case mounting, enabling fast connection of external radiators with 18 mm cut-outs and G1/4" threads

  • TypeFittings
  • Permanent bulkhead mounting secures external radiator links
  • Quick-disconnect design allows tool-free tubing changes
  • Locking ring prevents accidental uncoupling under vibration
  • Dual G1/4" internal threads connect internal loop
  • 18 mm panel cut-out fits standard case openings

Quick-release bulkhead fittings

The Alphacool ES coupling set mounts permanently in two 18 mm case openings and acts as a bulkhead connector for liquid-cooling loops. Male and female halves thread through the panel from opposite sides and secure with the supplied lock nuts. Internal G1/4" threads accept standard fittings for the internal circuit.

Sustained leak-free operation

The quick-disconnect mechanism is rated for permanent installation and allows repeated connection of external radiators without draining the loop. A locking ring snaps into the release sleeve to prevent accidental uncoupling under vibration or pressure cycles. An included opening tool eases separation when tubing runs are tight.

Nylon construction with G1/4" threads

Black nylon bodies resist corrosion and keep weight low for panel mounting. The set mates with Alphacool quick-release couplings 17537 and 17569 for a complete external-loop interface. No additional adapters are required when using standard G1/4" components inside the chassis.

商品問答

Does the 17598 coupling set generate any noise, heat or draw power when it stays connected all day?

The Alphacool ES quick release coupling set is a passive mechanical fitting with no moving parts, fans or electronics, so it produces no noise, no heat and consumes no power during continuous operation.

What existing fittings or tubing must I already have to use the 17598 set in my loop?

You need two G1/4" internal-thread connections inside the case for the water circuit and matching quick-release counterparts such as article 17537 or 17569 on the external radiator side.

Will the 17598 bulkhead fitting work alongside older G1/4" components I want to keep in the same loop?

Yes, the set uses standard G1/4" threads on both the internal and external faces, so it connects directly to any legacy G1/4" blocks, radiators or tubing fittings already in your system.
