Confirm the tube before ordering

This listing identifies Pentair part R172023 as a replacement tube for Rainbow automatic chlorine/bromine feeder models 300 and 302. The listed size is 3/8-inch outside diameter by 1/4-inch inside diameter by 8 feet.

Useful check: compare the old tube’s inner/outer diameters and length, then match your feeder model to the listing.
