PrimoChill Male to Female G 1/4in 25mm SX Extension Coupler diy cooling

Clearance Extension Coupler

This PrimoChill Male to Female G 1/4in coupler adds 25mm of reach between fittings so builders can route tubing around tight component layouts. The coated brass body threads directly into any standard G 1/4in port without adapters. An installed O-ring on the male side seals the joint before the loop is filled. It suits custom-loop builders who need a little extra spacing in a crowded chassis.

Sustained Loop Integrity

Under continuous coolant pressure the brass construction resists deformation and the single O-ring maintains a steady seal throughout long gaming or rendering sessions. No additional sealing compound is required because the factory-fitted ring seats against the female port on tightening. The fixed 30mm overall height keeps the assembly predictable when planning tube runs. The coupler does not restrict flow because its internal bore matches the G 1/4in thread standard.

Thermal Neutral Component

The coupler adds no active cooling surface so it contributes negligible heat to the loop and draws zero power. Coated brass resists corrosion from common coolants, keeping fluid chemistry stable over months of operation. With no moving parts it produces no audible noise under any load condition. Builders should verify clearance allowances in their case before ordering because the fixed length cannot be adjusted after installation.
