Alphacool HF 17225 Quick-Release Bulkhead

This G1/4" quick-release bulkhead fitting lets builders pass tubing through a panel and disconnect the loop without draining. The nut-locked coupling prevents accidental release while maintaining full flow. It suits custom water-cooling loops that need a secure, serviceable pass-through.

For builders who need a locked bulkhead disconnect

The bolted nut design adds security for vibration-prone or transport-heavy systems. Installers who prefer tool-free push-to-connect couplings or who do not require a bulkhead mount should choose a different style.

Nut-locked G1/4" bulkhead with dual internal threads

The 60.3 mm length and 261 mm diameter define the space needed on each side of the panel. Both sides accept standard G1/4" fittings so the loop configuration stays flexible. Brass construction with a Deep Black finish matches dark-themed builds.

FeaturesAlphacool's new quick-release coupling sets have been newly developed to offer extra security. For this reason, these couplings do not use a "click" mechanism but are bolted with a nut. The couplings can be no longer accidentally unlocked.

Questions about this item

Should I pick the bulkhead version or a straight quick-release for my loop?

The bulkhead design lets you mount the coupling through a panel or reservoir wall, sealing on both sides when disconnected, while a straight version would sit inline without panel mounting.

What does the 60.3 mm length mean once the fitting is installed in my case?

It measures 60.3 mm from face to face, so allow at least that much clearance between the bulkhead panel and any neighbouring component or tubing bend.

How does the G1/4" thread affect which fittings I can use?

Both ends accept standard G1/4" male fittings, letting you choose any compression, barb or rotary adapter that matches that thread.
