  • Product colorBlack
  • Key featuresThis bulkhead connector is perfect for applications such as

Color Black

  • 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
  • Works with soft PVC, silicone or neoprene tubing

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.
