This three-piece O-ring set is engineered for standard 10-inch water filter housings commonly found in residential systems, RV filtration units, and point-of-entry setups. Each seal is molded to the same dimensional profile as OR4 and OR-38, with updated EPDM designed for durability and consistent compression under pressure.
Key Features:
- 3 3/8″ inner diameter sized for most standard 10″ housings
- EPDM suitable for potable water and filtration environments
- Improved sealing resilience for hard water, vibration, and temperature cycling
- Made in the USA with direct-fit aftermarket dimensions
Functional Advantages:
- Helps maintain proper pressure integrity in whole-house and RV systems
- Supports leak-free operation after cartridge replacement or routine service
- Provides a reliable refresh for aging or flattened O-rings
- Optimized for filtration housings using round-profile seals rather than proprietary shapes
Compatibility Highlights:
Designed to match a wide range of common 10-inch housings, including models used in home filtration, RV water lines, and marine fresh-water systems. Cross-references multiple part numbers for brands that utilize OR4-style seals.
Installation Notes:
- Clean the groove before seating the new O-ring to ensure a proper seal
- Apply manufacturer-approved lubricant if required for easier closure
- Verify the housing is a “standard” 10-inch model—specialty housings may differ in profile
- Follow filtration system instructions to avoid pinching or uneven compression
Use Cases:
- Whole-house sediment and carbon filter housings
- RV and motorhome water treatment systems
- Marine and boat fresh-water housings
