Stainless Steel Male Run Tee – 3/8 in. Tube OD x 1/4 in. MNPT (SMRT 6-4N) (SMRT 6-4N)
The SMRT 6-4N is a compact, 3-way run tee engineered for high-integrity tube and threaded connections in pressure-rated and sanitary fluid systems. With a 3/8" tube OD, 1/4" Male NPT run, and a 1/4" Female NPT branch, this tee is built for performance where space is limited and sealing can’t be compromised.
Manufactured from corrosion-resistant 316 stainless steel, the SMRT 6-4N handles aggressive media, high pressures, and vibration-prone conditions commonly found in clean-in-place (CIP) setups, fuel lines, and analytical skids. Its dual-function layout allows for seamless integration between tube and NPT-threaded components, offering flexibility without sacrificing durability.
Fully compatible with Swagelok® style compression systems, this fitting is ideal for OEM builds, process instrumentation, and hygienic fluid distribution.
Key Benefits
- Multi-Connection: Mixed end types for easy tube-to-thread integration
- Seal Integrity: Compression and thread connections deliver secure, leak-tight performance
- Strength: Holds up under system cycling, vibration, and harsh media
- Precision: Machined to ANSI specs for reliable fit and repeatable installs
- Compatibility: Fits 3/8" tube and 1/4" NPT ports in high-spec assemblies
Typical Applications
- Sanitary stainless steel tubing systems
- Pressure instrumentation and gas distribution loops
- OEM process skids and analyzer panels
- Clean-in-place (CIP) fluid systems
- Fuel and chemical process control lines
