Purpose & Audience

The Alphacool G1/4" bulkhead connector fitting in Deep Black lets custom-loop builders pass tubing through a panel wall using two standard fittings. It suits enthusiasts assembling open or closed liquid-cooling circuits who need a clean, sealed pass-through for soft tubing such as PVC, silicone or neoprene.

Installation Notes

Drill a 21 mm mounting hole in the chassis panel, insert the brass body and secure it with the supplied lock-nut before threading the two G1/4" fittings into the inner threads. The short version leaves minimal protrusion, so verify panel thickness allows full thread engagement; over-tightening can strip the brass threads.

Decisive Specification

The fitting presents a G1/4" inner thread on both sides of the bulkhead, so it only works with fittings and tubing matched to that thread standard. Builders using hard-line tubing or proprietary quick-connect systems will need a different connector.

Highlights

  • G1/4" thread fits standard water-cooling loops
  • Brass body resists corrosion for long service life
  • Deep Black chromatised finish prevents peeling
  • 21 mm mounting hole suits common panel cut-outs

FeaturesThis bulkhead connector is perfect for applications such as looping through of tubing through the back or side of an enclosure with the help of two fittings. The bulkhead connector itself is safely fixated with the counter-nut and the 1/4“ inner threads can then be used to connect two fittings of your choice.
