5/8" ID Tubing Adapter
The Atlantic Water Gardens fountain pump 525 5/8-inch inner diameter tubing adapter is the mid-size outlet adapter for the Oase 525 Fountain Pump, bridging between the compact 1/2-inch and larger 3/4-inch adapter options. The 5/8-inch adapter is the right choice when the tubing or plumbing fittings in a particular installation are specified at 5/8-inch ID — common in some older fountain basin plumbing kits and certain flexible pond supply tubing formats.
Adapter Selection Context
The 5/8-inch adapter occupies the practical midpoint: it handles more flow than the 1/2-inch adapter without the bulk of the 3/4-inch connection — useful for medium-length single-outlet runs or for matching the exact tubing size already in an existing installation rather than replacing all tubing to accommodate a different adapter size. When selecting, measure the inner diameter of the tubing in your installation with a vernier or fit-check before ordering.
Installation
Connects to the Oase 525 pump outlet port via press-fit or twist mechanism. Secure the tubing joint with a hose clamp for a permanent, watertight installation.
