Component Type Bottom O-Ring
Housing Compatibility Double O-Ring Housing Systems
Position Bottom Seal (Sump Connection)

INSTALLATION & USE

Replacement Procedure

  1. Shut off water supply and depressurize the filter housing completely before opening
  2. Remove the housing sump and clean the o-ring groove thoroughly, removing any debris or old lubricant
  3. Position the new HOR-04-2 o-ring in the bottom groove, ensuring it sits evenly without twisting or pinching
  4. Apply food-grade silicone lubricant to the o-ring surface before reassembling the housing
  5. Hand-tighten the sump firmly, then pressurize slowly while checking for leaks at the seal point
COMPATIBILITY

System Requirements

The HOR-04-2 is designed for PureT double o-ring filter housings that feature a two-seal design with separate top and bottom o-rings. This bottom position o-ring secures the sump to the housing cap and is the primary pressure seal. Confirm your housing uses the double o-ring configuration before ordering, as single o-ring housings require different components. Not compatible with slim-line or standard single-seal housing designs.

🔧 Pro Tip: Replace both top and bottom o-rings at the same time, even if only one appears worn. O-rings age at similar rates, and replacing both prevents a second leak repair within months.
