Description

90-Degree Stainless Steel Elbow – 1/4" Tube x 1/4" Male NPT (SME 4-4N)

The SME 4-4N is a 90-degree male elbow fitting built for 1/4" tubing and 1/4" Male NPT connections. It’s designed for tight fluid routing in hygienic and industrial systems, delivering reliable, leak-free performance in compact layouts where space is limited and cleanliness is critical.

Made from 316 stainless steel, this fitting resists corrosion and holds up under repeated clean-in-place cycles. It’s a solid choice for pharmaceutical production, biotech manufacturing, and other high-purity environments where hygienic valves and sterile operation are required.

Engineers choose the SME 4-4N for its simple installation, long-term reliability, and ability to maintain precise fluid control under pressure.

Key Benefits

  • Seal: Metal-to-metal connection with leak-tight NPT threads
  • Durability: Withstands pressure, vibration, and frequent CIP procedures
  • Maintenance: Easily reinstalled with no loss in sealing performance
  • Compatibility: Fits standard stainless process tubing and components
  • Material: 316 stainless steel meets hygienic and industrial specs

Typical Applications

  • Sanitary fluid processing systems
  • Hygienic valve and piping layouts
  • Pharmaceutical and biotech production
  • Gas lines and clean fluid transfer
  • Clean-in-place (CIP) instrumentation
