Aqua-Computer cooling system part 41078 — compatible with Eheim 1046 and AquaStream

Aqua-Computer part 41078 is a set of two adapters designed to integrate pumps with non-standard ports into standard water-cooling loops. These adapters provide mechanical compatibility for pumps of the Eheim 1046 and AquaStream 12V types, converting their specific outlet/inlet geometry to conventional G1/4 tapered thread and sealing with an integrated O-ring gasket. The component is intended for use as a replacement part or extension within liquid cooling systems, facilitating repairs, upgrades or custom builds that require standard G1/4 fittings.

Advantages

The adapters are supplied as a matched pair to allow connection of both inlet and outlet ports using widely available G1/4 fittings. Built-in O-ring gaskets ensure a reliable seal without additional sealing materials, while the tapered G1/4 interface provides compatibility with common water-cooling hoses, rotary unions and fittings. The design simplifies maintenance and reduces the need for pump-specific or custom adapters when integrating Eheim 1046 or AquaStream-type pumps into standard cooling loops.

Suitable for

• Replacing worn or damaged pump ports on Eheim 1046 and AquaStream 12V style pumps
• Converting pump connections to standard G1/4 fittings for custom water-cooling builds
• Maintenance tasks where quick, compatible fittings are required
• Integrating legacy pumps into modern liquid-cooling systems

Key specifications

• Set contains two adapters for pump inlet and outlet
• Thread conversion to standard G1/4 tapered thread
• Integrated O-ring gasket for leak-resistant seal
• Designed for mechanical compatibility with Eheim 1046 and AquaStream 12V type pump ports
• Material: metal construction for durable mounting and repeated use

How to use

Turn off and drain the cooling loop before replacing or installing the adapters. Remove the original fittings or caps from the pump ports, verify port orientation and thread engagement, then insert the adapter into the pump port so the O-ring seats correctly. Hand-start the adapter and tighten with appropriate tools to the manufacturer's recommended torque for G1/4 fittings; avoid over-tightening to prevent damage to the pump housing or O-ring. Once both adapters are installed, connect standard G1/4 fittings or hoses and refill the loop, then perform a leak test at low power before normal operation.

Usage recommendations

Use compatible G1/4 fittings and check O-ring condition during routine maintenance. Replace the O-ring if it shows wear, flattening, or damage. Ensure the pump housing is free of debris before installation and use moderate torque to avoid threading or housing damage. After installation, perform a controlled leak test and monitor for any signs of seepage during the first operating hours.
