What It Does
The Graco 100483 is a pipe tee fitting used to split or combine fluid paths in a pressure line. It is commonly found in drain/return branches, priming lines, or auxiliary take-offs in Graco pump and sprayer plumbing.
Features & Benefits
- OEM geometry for correct thread engagement and alignment
- 3/8 NPT threads for common Graco fluid circuits
- Branching made simple: add drain/return or auxiliary line without re-plumbing the system
Fit & Installation Tips
- Confirm your model’s parts diagram lists 100483 and verify the required 3/8 NPT size.
- Use PTFE tape or a Graco-approved thread sealant on NPT threads; avoid over-tightening to prevent cracks or leaks.
- After installation, pressure-test and check all joints for seepage before returning to service.
