Why This O-Ring Matters
Choosing the correct seal ensures optimal system performance and prevents leaks or downtime in fluid handling systems:
- Superior sealing integrity: Designed for the specific assembly where leakage could compromise system operation.
- Genuine OEM quality: Ensures fit, durability and compatibility when replacing the original component.
- Suitable for high-stress environments: Engineered for use in assemblies where fluid pressure and return flows demand specific sealing geometry.
Installation & Maintenance Tips
Follow these recommendations to get long service life and avoid issues:
- Shut down and depressurize the system before opening any fluid-carry components.
- Inspect surrounding sealing surfaces and grooves—replace the 104444 if signs of wear or distortion are present.
- Ensure the O-ring is seated properly and the groove is clean and free of debris or damage.
- Keep a spare 104444 part on hand if you regularly service the assembly it belongs to—reduces downtime.
Frequently Asked Questions
The 104444 part is specified for particular Graco assemblies as listed in the parts manual. Using it elsewhere may require checking dimensions, groove fit and pressure rating. :contentReference[oaicite:6]{index=6}
Replacement depends on usage, fluid type and operating pressure. Inspect each time the assembly is opened; if you notice deformation or fluid seepage around the seal, install a new 104444 part.
Improper installation (twisted seal, mis-seated groove or damaged surface) can lead to fluid bypass or leaks, which can degrade system performance and increase maintenance. Always follow OEM guidance.
