Pentair Rainbow 5/8" x 18" Chlorinator Hose Tube | R172253Z
The Pentair Rainbow 5/8" x 18" Chlorinator Hose Tube (R172253Z) is a replacement vinyl hose designed for automatic chlorinator systems and chemical feeders in pools and spas. Sized at 5/8" inside diameter and 18" long, this hose tube helps deliver chemical feed from the chlorinator to your pool plumbing or equipment, ensuring a smooth, controlled flow of sanitizer where it’s needed.
What This Part Is For
This chlorinator hose tube is used with Pentair Rainbow chlorinators and similar automatic chemical feed devices that rely on flexible tubing to route chemicals into the pool circulation system. Replace this hose when it becomes brittle, cracked, clogged, or discolored to maintain proper chemical delivery and prevent leaks or flow restrictions.

- Ideal replacement hose tube for chlorinators, feeders, or similar low-pressure chemical lines
Installation Notes
- Turn off the chlorinator and pool pump before servicing

- Push hose fully onto barbed fittings and secure with clamps if recommended
Maintenance Tips
- Check the hose periodically for cracking, stiffness, or discoloration
