Built from heavy-gauge cast iron, the Raypak 006731F Return Header is manufactured to satisfy the rigorous requirements of ASME-rated heating systems. This robust header directs heated water through the return circuit with minimal flow resistance, promoting efficient heat distribution and steady system output. Cast iron's inherent strength and thermal stability make the 006731F highly resistant to cracking and deformation, even under the sustained temperatures and pressures found in commercial and high-demand residential applications. Whether you are performing a scheduled component refresh or addressing a failing header, the 006731F delivers the heavy-duty performance ASME installations demand.

Key Benefits

• Heavy-Gauge Cast Iron Construction: Delivers outstanding structural integrity and thermal stability, standing up to the demanding conditions of ASME-rated heating systems.
• Meets ASME Compliance Standards: Manufactured to satisfy strict ASME quality and safety requirements, giving you confidence in both performance and code adherence.
• Low-Restriction Water Flow: Optimized internal passages minimize flow resistance, enabling efficient heat distribution and consistent system output.
• Exceptional Resistance to Wear: Cast iron's natural durability resists cracking, corrosion, and deformation, reducing the need for premature replacement.
