The Raypak 010057F Tube Bundle is a full ASME-certified copper heat exchanger kit, designed for Raypak 336A (Atmospheric) and 337A (Low-NOx Digital) metal-header pool heaters. This OEM bundle includes nine copper tubes, mounting studs and bolts, baffle plate, and header gasket, crafted to restore thermal performance, efficient flow, and full sealing integrity in the firebox. When original bundles corrode, scale, or fail, replacing them with this complete kit helps ensure safe heat exchange, proper sensor operation, and long-term durability under rigorous operating conditions.
-
Complete OEM Replacement Kit: Includes all necessary parts—nine copper tubes, baffle plate, header gasket, and all hardware—for a full drop-in installation that restores the heater’s integrity.
-
ASME Certified Copper Design: Metal headers and copper tubes comply with ASME standards to withstand high heat, pressure, and harsh pool water conditions, reducing risk of warping or leaks.
-
Specifically Made for 336A & 337A Models: Engineered to align perfectly with Raypak 336A (atmospheric) and 337A (Low-NOx) heaters—ensuring correct sensor fit, header connection, and firebox dimensions.
-
Restores Thermal Efficiency & Flow: Fresh copper tubes and clean internal pathways help improve heat transfer, reduce resistance, and improve overall performance, especially after aging or scaled bundles.
-
Built for Durability Under Heat & Corrosion: Designed to endure repeated thermal cycling, exposure to combustion heat, and corrosive pool water, helping extend heater life and minimize downtime.
