Loop Extension Fittings

These male-to-female extenders add 40 mm of spacing to a G1/4" liquid cooling loop, letting builders bridge larger gaps between blocks, radiators and reservoirs. The six-piece pack suits custom loops that need extra reach without adding angled adapters.

Sustained Thermal Load

Chrome-plated brass construction maintains structural integrity and corrosion resistance during continuous coolant circulation, while the concealed O-ring groove preserves a leak-free seal over long operating periods. Heat dissipation through the metal body remains consistent as loop temperatures stabilise.

Tool-Free Installation

Each fitting threads by hand into standard G1/4" ports, and the included O-rings seat automatically when tightened, eliminating the need for wrenches or sealant. The only common issue is cross-threading if the first turn is forced, so start every connection gently.

Questions about this item

Do these 40 mm extender fittings add noticeable heat to a loop running all day?

Chrome-plated brass construction helps dissipate heat from the coolant, so the fittings themselves do not become a thermal bottleneck during continuous operation.

What thread standard must my existing blocks and radiators use for these G1/4″ male-to-female extenders to connect?

Every component in the loop needs G1/4″ threads; the extenders mate directly with that standard on both sides.

Will the 18 mm outer diameter clear the ports on my older water blocks and radiators?

The 18 mm OD matches the common G1/4″ form factor, so it fits legacy blocks and radiators that use the same thread spacing.
