adaptor is necessary to integrate pumps produced by Eheim into a water-cooling
loop. It adapts the pump’s thread to the G1/4” threads commonly used in
water-cooling setups. This way, any G1/4” fittings may be used with the pump.
notice that different Eheim pumps utilise different thread sizes, and even on
one pump inlet and outlet threads might differ. Be careful to choose the
adaptor fitting your pump.
adaptor is only needed, when no add-on reservoir (e.g. AB-K) is used.

Strong tightening of the Adaptor may damage the pump. To prevent fractures,
only tighten finger-tight. An O-ring provides sealing.
