Danner AP20 Extension Tubing — 5/8 in × 20 ft

More reach between your AP20 and its manifold

Danner 12158 is a 20-foot roll of thick-wall, kink-resistant black vinyl tubing with a 5/8-inch inside diameter. It is the manufacturer-specified optional main-hose extension for the Danner AP20 air pump.

• One 20-foot roll; cut to your required length.
• For the AP20 pump-to-manifold connection only.
• The AP20 already includes a short coupling hose, clamps and manifold; this roll is optional when you need additional reach.

Choose the right connection

This is not small branch airline, is not the AP60 main hose, and is not confirmed to connect directly to our skeleton ornament. Small manifold outlets, air stones and ornaments need separately matched airline and accessories.

Pair it with the Danner AP20 pump. Follow the pump manual for installation and airflow adjustment.
