2 inch x 1-1/2 inch Brass Reducing Coupling Female x Female

2 Inch x 1-1/2 Inch Brass Reducing Coupling – Threaded FIP x FIP Adapter

This brass reducing coupling is designed for applications requiring a transition between two nominal pipe sizes using female threaded connections. Featuring a 2-inch FIP inlet and a 1-1/2 inch FIP outlet, this fitting enables secure, corrosion-resistant connections in water distribution, mechanical, and process piping systems.

Fabricated from lead-free brass, it complies with current potable water system requirements and provides long service life in both hot and cold water installations. The uniform threading ensures compatibility with standard NPT pipe fittings in commercial, industrial, and residential plumbing systems.

Key Product Attributes

• ✅ Lead-Free Brass Composition – Meets NSF/ANSI 61 and 372 standards for use in potable water applications.
• ✅ Threaded FIP x FIP Ends – Precision-machined threads deliver consistent sealing with NPT-standard fittings.
• ✅ Corrosion-Resistant Alloy – Suitable for environments with fluctuating pressure and temperature conditions.
• ✅ High Mechanical Strength – Withstands service pressures common in domestic and light commercial piping systems.

Installation Guidelines

Install using thread sealant or PTFE tape to ensure proper hydraulic sealing. Avoid overtightening, as excessive torque may damage threads or compromise system performance. Proper alignment and support of connected pipework is essential to maintain joint integrity under load or thermal expansion.

Typical Use Cases

• Reducing connections between dissimilar pipe sizes in threaded supply or return lines.
• Used in retrofit installations, equipment hookups, or piping system modifications.
• Applicable in water supply, hydronic heating, and non-potable utility piping.

Material Performance Note

Brass fittings are widely used in the industry for their ability to resist dezincification and scale formation. Their compatibility with a range of fluids and piping materials makes them a preferred choice for transition fittings in mixed-material systems.
