greenDracaena D-G-Extender G1/4" 7.5mm Extender Fittings 6 Pack White

G1/4" Extender Fittings for Tight Loops

These chrome-plated brass extenders add 7.5mm of clearance between components in a custom liquid cooling loop. The male-to-female G1/4" threading fits standard water cooling hardware and the white finish suits light themed builds. Six fittings are included, each with a pre-seated O-ring in a concealed groove. They are intended for builders who need a little extra spacing without adding bulk.

Tool-Free Install with Concealed O-Rings

Each fitting threads by hand into a G1/4" port and the matching female end accepts any standard G1/4" compression or barb fitting. The O-ring sits inside a machined groove so it cannot roll out during assembly. Over-tightening with tools can strip the brass threads, so finger tight plus a slight nip is enough. No special tools or sealants are required.

Check Thread Depth and Clearance First

Verify that your blocks, radiators, reservoirs and pump tops all use G1/4" threads before ordering. Measure the available gap between adjacent ports; the 18mm outer diameter and 7.5mm height need that much space side to side and vertically. If your loop uses proprietary thread sizes or the ports are recessed deeper than the male thread length, these extenders will not seal.
