Product Details

The Navien 20011438A is a genuine OEM replacement O-ring designed for use in Navien tankless water heater systems. This precision-engineered sealing component ensures leak-free operation in critical waterway assemblies.

Key Features:

  • EPDM (Ethylene Propylene Diene Monomer) rubber construction for superior durability
  • Excellent resistance to heat, ozone, and weathering for long-term reliability
  • P14 size designation for precise fitment in Navien systems
  • Forms a tight, reliable seal between plumbing components to prevent leaks
  • NSF certified for potable water applications (EWK270 rating)
  • Genuine Navien factory part ensuring exact specifications and quality

This O-ring is commonly used in waterway assemblies and water adjustment valve (WAV) installations on various Navien NPE series tankless water heaters. Regular replacement of O-rings during maintenance helps maintain optimal system performance and prevents costly water damage from leaks.

Very good service

easy purchase and in stock items

Every thing was good just taking longer to ship then expected

The product was in stock as advertised and received promptly; as compared to other that advertise but do have the item available at all.

I ordered a part for my RV furnace. You shipped it out in a reasonable time, but the part was delayed by the USPS and I received it almost a week after I ordered it. Since it was delayed & I could not wait for it, I got the same part from another place. After I received your part late, I called and requested a return. I was very satisfied with the return process & received notice yesterday that a refund had been issued. All in all, I was very satisfied with your service, but not with USPS.

Ordered the tailgate Diamond Plate DeeZee 2123 for my 1997 F350 and your site has the best prices on the internet. Thanks for making it easy to get truck parts. Have a great day.
