Phobya G1/4 Knurled Extension Fitting MSV 64085

SKU CH-XQ6V-11ZJD MPN 64085

G1/4 male-to-female extension adds thread length so angled fittings line up cleanly

  • Extends G1/4 threads for easier angled-fitting installation
  • Knurled surface gives secure hand-tightening grip
  • Matches input and output hose directions at different heights
  • Brass construction resists corrosion in liquid-cooling loops
  • Single extension fitting included for immediate use

Purpose and fit

The Phobya G1/4 knurled extension fitting adapts a male G1/4 thread to a female G1/4 thread, adding length between components in a custom liquid-cooling loop. It suits builders who need extra clearance to align angled fittings or to route tubing without sharp bends.

Behaviour under load

The brass body resists deformation and corrosion during continuous coolant circulation, maintaining a reliable seal at typical loop pressures. The knurled surface allows secure hand tightening so joints stay sealed through thermal cycling and vibration.

Build and connections

Each package contains one extension fitting with G1/4 outer and inner threads finished in nickel-plated brass. The added thread length lets mismatched port heights line up, simplifying tube routing and reducing stress on adjacent fittings.

Questions about this item

Does the knurled MSV extension add audible vibration or heat when coolant circulates continuously?

The brass extension is a passive thread adapter with no moving parts, so it generates no noise or heat of its own during continuous flow.

Which thread standard must my existing blocks and radiators already use for this G1/4 extender to seal correctly?

Every connected component must provide a matching G1/4″ (BSPP) port — outer thread on one side, inner thread on the other — for the extender to engage properly.

Will the 64085 extender align correctly with older Phobya angled fittings that sit at a different height?

Yes, the extender raises the connection point so hoses on mismatched-height angled fittings can run parallel in the same direction.
