1/2 inch Stainless Steel Tee Female x Female x Female

1/2 Inch Stainless Steel Tee – FIP x FIP x FIP, Schedule 40

The 1/2 inch stainless steel tee features three female NPT threaded ends and is used for branching pipe systems in potable water, industrial, or hydronic applications. Constructed from corrosion-resistant stainless steel, this fitting supports high-pressure service and is suitable for installation in both residential and commercial environments where reliability and material compatibility are critical.

Material Properties and Compliance

This tee is manufactured from 304 or 316 stainless steel (depending on specification) and meets applicable industry standards for pressure fittings. It conforms to ASME B16.11 for forged fittings and ASME B1.20.1 for NPT thread dimensions. Suitable for use in potable water systems when certified to NSF/ANSI 61 and 372.

• ✅ Material: Stainless Steel 304 or 316 (ASTM A182 or A351)
• ✅ Threads: NPT per ASME B1.20.1
• ✅ Service Rating: Up to 150 psi for water at ambient temperatures (varies by grade and wall thickness)
• ✅ Compliance: NSF/ANSI 61 and 372 compliant for potable applications (if specified)

Technical Specifications

• Nominal Size: 1/2 inch
• Connection Type: FIP x FIP x FIP (Female Iron Pipe Thread)
• Wall Rating: Schedule 40 (standard for threaded stainless fittings)
• Temperature Range: Up to 400°F for non-potable systems (consult material-specific limits)

Installation Considerations

Use PTFE tape or pipe thread compound on male threads to ensure leak-tight connections. Avoid overtightening to preserve thread integrity and prevent cracking. Tighten using appropriate hand tools on the fitting body, not the branches, to reduce mechanical stress. Compatible with stainless steel, brass, or galvanized pipe systems when galvanic corrosion is addressed through dielectric separation or appropriate materials selection.

Applications

This fitting is used in closed-loop hydronic heating systems, domestic water supply branches, compressed air lines, and chemical distribution systems where corrosion resistance and mechanical strength are required. Suitable for use in both vertical and horizontal configurations, and approved for use in above-ground and exposed service environments.

Note on Corrosion Resistance

Stainless steel provides superior resistance to oxidation, scale, and most water-borne contaminants. Type 316 offers enhanced performance in chloride-rich or marine environments. Ensure compatibility with system media and adjacent piping materials to prevent galvanic reaction.
