Product Overview

The Raypak 018155F Water Union and O-Ring Kit provides replacement plumbing connection components for compatible Crosswind pool and spa heaters. The unions create serviceable connections between the heater and pool plumbing, allowing the heater to be disconnected for maintenance without requiring extensive modification of the surrounding plumbing.

The included O-rings provide the sealing surfaces required at the union connections and should be properly seated during installation to help prevent water leaks. The 018155F is a practical OEM replacement when existing unions or seals become damaged, worn, or lost during heater service. Always verify compatibility with the specific Crosswind heater model before installation.
