Stainless Steel Female Run Tee – 3/8" Tube x 1/4" FNPT (SFRT 6-4N)
The SFRT 6-4N is a stainless steel female run tee designed for precise, leak-tight integration of tube and pipe thread connections. This tee features two 3/8" compression tube ends and one 1/4" FNPT threaded run, allowing engineers to merge tubing with pipe-threaded instruments, valves, or sensors without needing thread adapters.
Machined from solid 316 stainless steel, this fitting delivers corrosion resistance, high pressure tolerance, and long-term performance in both sanitary and rugged industrial systems. It’s built for engineers who need reliable transitions between compression and NPT systems—without sacrificing cleanliness or mechanical strength.
The SFRT 6-4N supports clean-in-place (CIP) cycles, vibration-prone environments, and rapid system servicing. It’s fully reusable, with consistent sealing and torque repeatability across maintenance cycles.
Key Benefits
- Converts compression tubing to a female NPT outlet in a tee format
- Made from 316 stainless steel for sanitary and industrial durability
- Handles high pressure and frequent thermal cycling
- Compression ends offer leak-tight, sealant-free installation
- FNPT port accepts standard 1/4" threaded instrumentation or flow control
- Polished finish minimizes fluid contamination risk in hygienic systems
- Reusable for system upgrades or maintenance without degrading seal integrity
