Barrow G1/4" D-Plug Fitting

This Barrow Mods fitting connects two female G1/4" ports in a custom water-cooling loop. The nickel-plated brass body is finished in black and measures 15 mm in overall length. It is designed for DIY builders who need a secure, leak-free joint between rigid or flexible tubing components.

1.5 mm adjustable extension

The detachable centre section provides 1.5 mm of axial extension for micro-adjustment and rotational alignment during assembly. Two thick gaskets seal the moving joint to maintain a leak-free connection. The manufacturer specifies that the extension must not exceed 1.5 mm.

Suits single-plane alignment tweaks

Builders who need a small amount of play to line up hard-tube runs or to rotate a block will find this fitting useful. It is not intended for loops that require larger axial movement, angled offsets or quick-disconnect functionality.

Questions about this item

How does the 15 mm length affect loop planning?

The 15 mm body gives a compact connection point between two female G1/4" ports, keeping tubing runs tight in small cases.

What does the G1/4" thread cap in practice?

G1/4" is the standard PC water-cooling thread, so the fitting mates with any G1/4" female port on blocks, radiators, reservoirs or pumps.

How much clearance is needed to install the D-plug?

Allow at least 15 mm straight clearance plus room for a wrench on the hex; the centre section separates for micro-adjustment up to 1.5 mm.
