What it is
This is a Navien O-ring manufactured in EPDM rubber to a V32 profile, sized 31.5 x 4T and supplied in black. It is a sealing component used within the hydraulic assemblies of Navien LCB 700 series boilers, where it prevents water loss at a mating joint. The NSF designation indicates the material is listed for use in contact with water.
Signs this part needs replacing
- Water weeping or dripping from the joint the O-ring seals
- Visible cracking, splitting or flattening of the ring
- The rubber has hardened or lost its elasticity
- Scale or corrosion debris sitting in the seal groove
- A leak that returns shortly after the joint is re-tightened
Before you order
- Confirm your boiler model and serial number against the fitment list above
- Check the profile and dimensions of the O-ring removed from the appliance
- Inspect the seal groove and mating face for damage or debris before fitting
- Confirm how many O-rings the joint requires
