Phobya Eheim 1046/48 G1/8 to G1/4 Adaptor Black Nickel 52087

Direct pump-to-loop connection

The Phobya Eheim 1046/48 adaptor replaces the stock outlet on compatible Eheim pumps so any standard G1/4 fitting can be used. It bridges the proprietary G1/8 port to the wider G1/4 thread found on most water-cooling components. The single-piece brass construction keeps the flow path short and unrestricted. This fitting is aimed at builders who want to integrate an Eheim pump into a custom loop without proprietary hose barbs.

Thermally neutral passive component

As a solid brass fitting it adds no active heat, noise or power draw to the system. Fluid passes through the straight bore without restriction that would raise pump workload. The black nickel plating resists corrosion and does not degrade coolant chemistry over time. No electrical connection or control signal is involved.

Knurled grip and captive O-ring

External knurls allow hand-tight installation without tools while still achieving a reliable seal. A captive O-ring sits in a machined groove; the manufacturer advises moistening it before insertion to prevent twisting and ensure a leak-free joint. The 52087 model ships as a single adaptor ready to thread directly into the pump outlet. Builders who need multiple pump connections or a different thread standard will require additional fittings not included here.
