Replacement O‑ring designed for Wilkins model 375 backflow assemblies with a 1" housing inlet. This part corresponds to part number 227N and provides a tight sealing surface at the housing inlet to help protect the assembly from leaks and maintain reliable performance during routine operation.

  • Exact fit: Intended for the Wilkins 375 series housing inlet with a 1" connection; confirm part number 227N before installation.
  • Function: Creates a pressure-tight seal at the inlet to prevent water bypass and maintain correct backflow prevention operation.
  • Installation guidance: Replace any worn or cracked O‑ring during routine service intervals; inspect the housing seat and groove for debris or damage before installing.
  • Service considerations: Use a compatible lubricant (silicone-based recommended) to ease installation and avoid damage; do not use petroleum-based lubricants unless manufacturer approves.
  • Compatibility check: Verify match by comparing the part number and the 1" housing inlet measurement to your existing component.

Material composition and manufacturer warranty details are set by the original equipment manufacturer; if you require confirmation of elastomer type, shelf life, or OEM warranty coverage, contact the Wilkins/Zurn technical support or consult the product catalog before ordering. For safe replacement: shut off and depressurize the system, carefully disassemble the housing, remove the old O‑ring, clean the sealing surfaces, fit the new O‑ring with appropriate lubricant, and reassemble. If you are unsure about any step, consult a licensed plumber or certified backflow technician.
