Thermaltake 30 mm G 1/4 Extender Fitting

This brass extender joins two G 1/4 male threads in a custom liquid-cooling loop. The 30 mm length adds spacing between components such as radiators, blocks or reservoirs. Black chrome plating protects the copper alloy body from corrosion. It suits builders who need a rigid, fixed-length connector rather than a flexible tube run.

Installation and common issues

Each end carries a G 1/4 female thread that screws onto standard male fittings by hand, then snugs with a spanner on the 22 mm hex flats. Over-tightening can strip the brass threads, so stop when the O-ring seats. The rigid body does not bend; mis-aligned ports will stress adjacent seals. Ensure both mating surfaces are clean and the O-rings are seated before final torque.

Capacity and headroom

The 30 mm extension bridges modest gaps between fixed components without adding flow restriction. The straight-through bore maintains high flow rates typical of G 1/4 loops. It cannot compensate for large offsets or angular misalignment; those situations require rotary or angled fittings instead. Weight is 63 g, adding minimal load to the mounting points.
