High-Purity Stainless Steel 304/316L Reducer Tee Press Fittings for Fluid Systems

Overview

The High-Purity Stainless Steel 304/316L Reducer Tee Press Fittings are precision-engineered pipe components designed to connect pipes of different diameters in press-fit systems while maintaining flow integrity and cleanliness. Constructed from 304 or 316L stainless steel, these tees feature a press-fit design (ISO 6122 compliant) and a smooth bore, ideal for high-purity and corrosive fluid applications.

Features

Premium Material & Finish:

304L (low carbon) or 316L (extra low carbon) stainless steel, with a passivated surface (Ra ≤0.8μm) for high-purity systems, reducing metal ion leaching in pharmaceutical and semiconductor processes.

Seamless construction (no welds) minimizes particle entrapment, critical for ultra-pure water and gas applications.

Press-Fit Technology Advantages:

ISO 6122-compliant press ends create permanent, leak-free joints in 3 seconds using a hydraulic press tool, reducing installation time by 50% compared to threaded reducers.

Compatible with stainless steel, copper, and PEX pipes (OD: 15mm-63mm), with visual indicators (deformed press ring) to confirm proper seating.

Flow-Optimized Design:

Reducer tee design (e.g., 54mm x 42mm) ensures smooth transition between pipe sizes, with a 45° inlet angle minimizing turbulence and pressure loss by 20% compared to sharp reducers.

Reinforced branch connection (1.5x wall thickness) withstands pressure surges in multi-line systems, suitable for up to 16 bar (232 PSI) at 20°C.

Compliance & Certification:

Meet EN 10226-1, NSF/ANSI 61, and 3-A Sanitary Standards, with material traceability reports and mill certificates available for critical applications.

316L variant offers superior intergranular corrosion resistance, ideal for welding in high-purity systems without post-weld annealing.

Application

Perfect for high-purity and corrosive fluid systems:

Pharmaceutical Manufacturing: Connecting clean steam lines and purified water (PW) systems, with 316L stainless steel meeting USP Class VI and FDA 21 CFR Part 177.

Semiconductor Fabrication: Ultra-pure water (UPW) and chemical mechanical planarization (CMP) lines, with passivated surfaces preventing particle contamination.

Food & Beverage: Beverage blending systems and dairy pasteurization lines, compliant with 3-A Sanitary Standards for direct food contact.

Biotech & Research: Laboratory fluid transfer lines for cell culture media and reagents, with press-fit connections eliminating the risk of thread contamination.

FAQ

Q: Can these reducers be used with plastic pipes?

A: Yes, compatible with PEX and PB pipes with the correct OD, but avoid using with rigid plastic pipes under high pressure.

Q: What is the temperature range for 316L stainless steel?

A: -250°C to 450°C, suitable for cryogenic ethanol lines and hot water sanitization systems.

Q: How to clean the fitting for high-purity applications?

A: Use deionized water flushing or steam sterilization; avoid abrasive cleaners that may scratch the passivated surface.

Q: Can the press-fit connection be used in vacuum systems?

A: Yes, the mechanical interlock provides reliable sealing in vacuum conditions (down to 29" Hg), but metal-to-metal seals are recommended for extreme vacuums.
