ISTA Hose Adaptor

• Applied to 12mm and 16mm diameter hose.
• Hose fastening nodes prevent hose from loosing.

Specifications

What it is. A push-fit adaptor for stepping between 12mm and 16mm aquarium hose, so equipment built for one hose size can be connected to tubing of the other.

Fitting. Ribbed fastening nodes on the barb grip the inside of the hose, which is what keeps the hose from working loose under water pressure: a plain smooth barb wouldn’t hold as well over time.

Where it’s used. Canister filter inlet/outlet runs, external pump plumbing, or anywhere two hose diameters need to meet.
