Resideo 392877 Fitting

The Resideo 392877 is a mission-critical 1/4" Barbed Vent Fitting engineered for field-proven reliability in gas manifold configurations. Designed to facilitate a secure, leak-free connection between the vent port and the external atmosphere or combustion chamber, this component is a direct replacement for the Resideo 392877/U. It is essential for ensuring proper pressure regulation and preventing hazardous gas accumulation within the pilot or regulator assembly. This Resideo vent fitting is fully compatible with a wide range of industry-standard gas valves, including the VR8200, VR8300, VR8204, and SV9501 series. Constructed from high-durability materials to withstand cyclic thermal stress, the 1/4 inch barb design provides a positive grip for tubing, ensuring an airtight seal during high-demand operation. For technicians servicing commercial or residential boilers and furnaces, this Honeywell Resideo gas valve accessory ensures system safety remains within factory parameters by maintaining a stable reference to atmospheric pressure.

• Universal Compatibility: Seamlessly integrates with VR8200, VR8300, VR4200, and SV9501 gas control valves.
• Airtight Seal: The precision-engineered 1/4" barbed profile prevents vacuum leaks and pressure fluctuations.
• Identical Utility: The 392877 and 392877/U are functionally interchangeable, allowing for simplified truck stock management.
• Rugged Construction: Built for high-heat environments to prevent material fatigue and cracking over long-term service cycles.

Is the 392877 compatible with smart gas valves?
Yes, it is designed for use with several SmartValve series, such as the SV9501 and SV9502, ensuring accurate venting for integrated igniter and valve controls.

What is the difference between the 392877 and the 392877/U?
Technically, there is no performance difference. The "/U" suffix typically denotes universal packaging, but both part numbers refer to the exact same 1/4" barb vent fitting.

Can I use this for propane (LP) applications?
This fitting is compatible with both natural gas and liquid propane systems, provided it is matched with the appropriate gas valve model and pressure regulator setting.
