1-1/2" x 1-1/2" x 1/2" Carbon Steel Press Reducing Tee – For Sealed Mechanical Piping Systems

The 1-1/2" x 1-1/2" x 1/2" Carbon Steel Press Reducing Tee is a mechanically pressed fitting designed for use in sealed piping systems conveying water, air, inert gases, or other compatible fluids. This reducing tee allows for a branch connection of smaller diameter while maintaining full flow through the main line. It is manufactured to support mechanical system layout flexibility and consistent sealing under rated pressure conditions.

Constructed from corrosion-resistant carbon steel with a zinc-nickel coating, this press tee is compatible with industry-standard press tools and jaws. The fitting includes factory-installed sealing elements (typically EPDM) and is engineered for use in applications requiring flame-free, permanent joints that meet performance and safety criteria under pressure.

Technical Specifications

• Main Run Size: 1-1/2" x 1-1/2"
• Branch Size: 1/2"
• Material: Carbon Steel (zinc-nickel coated)
• Connection Type: Press x Press x Press
• Sealing Element: EPDM (factory-installed)
• Pressure Rating: Up to 200 PSI (dependent on system type and temperature)
• Applicable Standards: ASTM A420, ASME B16.51, NSF/ANSI 61 and 372 for potable water applications

Installation Requirements

Install using approved press tools and compatible jaw profiles specific to carbon steel systems. Ensure pipe is properly deburred and marked before pressing. Verify sealing element is undamaged and seated correctly in the bead. Perform pressure testing per system specifications once pressing is complete. Do not use for steam or fuel gas systems unless explicitly approved.

Common Applications

This reducing tee is typically used in closed-loop hydronic systems, chilled water distribution, domestic water supply lines (where approved), and compressed air or inert gas piping. It provides a compact solution for line reductions without the need for additional couplings or reducers.

Material Performance Insight

Carbon steel press fittings are selected for their mechanical strength, corrosion protection, and suitability for flame-free installation. The zinc-nickel coating enhances external corrosion resistance in exposed or high-humidity environments, and the EPDM sealing elements ensure leak-tight performance within specified temperature ranges.
