Barrow G1/4 inch Extension Straight MF 30 — black, G1/4 inch male-to-female straight extension, 30 mm

Barrow G1/4" Extension Straight MF 30 is a 30 mm straight male-to-female G1/4" extension in black finish designed for water-cooling and PC loop assemblies. It provides a compact solution to extend existing G1/4" threaded fittings while preserving thread compatibility. The straight MF configuration maintains alignment and allows easier connection in confined spaces without changing tubing routing.

Advantages

The extension offers a reliable female-to-male transition that keeps standard G1/4" threading intact, enabling quick installation and replacement of fittings. Its 30 mm length gives consistent spacing to improve access to tight radiator, pump or reservoir ports. Finished in black, the extension blends with typical water-cooling components and reduces visible metal contrast while keeping a stable, leak-resistant connection when installed correctly.

Suitable for

• Extending G1/4" ports on radiators, pumps, reservoirs and distribution blocks
• Improving access to fittings in compact PC cases and tight build areas
• Maintaining tubing layout while swapping or repositioning components
• Temporary or permanent thread extension where a straight male-to-female spacer is needed

Key specifications

• Thread type: G1/4" male-to-female straight coupling
• Overall extension length: 30 mm
• Finish: black coating
• Material: metal construction suitable for liquid-cooling use
• Connection orientation: straight, inline alignment

How to use

Hand-start the male thread into the existing G1/4" female port to ensure correct alignment, then tighten using an appropriate wrench until snug; avoid over-tightening to prevent thread damage. After fitting the extension, attach the corresponding G1/4" fitting or component to the female end and verify the seal. For leak-sensitive assemblies, use an appropriate sealing method such as PTFE tape or a compatible gasket according to the rest of the loop's assembly conventions. Perform a pressure or leak test of the loop before powering the system.

Recommendations

Use the extension in combinations with compatible G1/4" fittings and verify material compatibility with coolants. Ensure all connections are clean and free of debris before installation, and follow a controlled leak test procedure after assembly.
