Honeywell 14026 Siphon Loop

As a seasoned technician, you know that protecting high-precision controllers from the destructive force of live steam is non-negotiable. The Honeywell 14026 Siphon Loop, also known as a pigtail siphon, is a critical steam trap accessory engineered to provide a thermal buffer between your steam pressure controls and the boiler main. This 180-degree loop is constructed from heavy-duty black iron to withstand the rigorous demands of industrial and commercial steam-heated HVACR systems. By allowing condensate to collect and cool within the loop, it creates a reliable water seal that prevents high-temperature vapor from reaching the sensitive bellows of your Honeywell L404, L604, or L91 series Pressuretrols. Featuring a standard 1/4 inch NPT external thread, this 180-degree siphon loop ensures a seamless, leak-resistant connection to your main or high-pressure steam line. For any contractor managing condensate drainage and pressure regulation, the Honeywell 14026 is the industry standard for maintaining operational efficiency and preventing premature component failure in harsh boiler environments.

• Thermal Protection: Rapidly drops steam temperature to form a protective condensate seal, shielding vaporstat and pressuretrol internals.
• Extreme Durability: Forged from black iron to resist corrosion and handle high-pressure fluctuations in commercial steam loops.
• Universal Compatibility: Specifically designed for Honeywell L404, L408, L91, and P7810A/B series controllers.
• Simplified Installation: Standard 1/4 inch NPT threading allows for fast, secure mounting directly onto the steam tap inlet.
• Compact Header Design: The 180-degree configuration provides essential cooling in tight mechanical room footprints.

How does a pigtail siphon prevent controller damage?
In steam-heated HVAC systems, the loop traps water (condensate). This "slug" of cool water acts as a physical barrier, ensuring the Honeywell 14026 allows pressure to transmit to the sensor while blocking the 212?F+ steam from melting or warping the control's internal components.

Can this siphon be used on high-pressure steam boilers?
Yes, the black iron construction and 1/4" NPT threads are rated for main or high-pressure steam applications, making it suitable for most commercial boiler headers where Honeywell pressure components are utilized.

What is the proper orientation for installing the 14026 loop?
It must be installed vertically above the steam tap. This ensures gravity holds the condensate in the 180-degree bend, maintaining the necessary water seal between the boiler and the steam trap siphon loop.
