• ✅ Corrosion-Resistant Alloy Offers long-term reliability even in aggressive water conditions or dissimilar metal systems.
• ✅ Thread Integrity Precision-machined NPT threads provide a consistent seal with reduced risk of thread deformation during installation.
• ✅ Robust Wall Thickness Designed to handle pressure variations in water distribution systems.
• ✅ Service Versatility Compatible with both hot and cold water lines, as well as air and inert gas applications.

Technical Specifications

• Material: Lead-Free Brass (compliant with NSF/ANSI 61 & 372)
• Size: 1-1/4 inch nominal pipe size
• Connection Type: Female National Pipe Taper (FNPT) both ends
• Application Rating: Suitable for potable water, air, and low-pressure hydraulic systems

Application Use

This coupling is suited for new construction and retrofit work in domestic water systems, mechanical piping layouts, and distribution manifolds where a secure, leak-resistant joint is needed. It’s regularly installed where two male-threaded brass, copper, or steel lines require reliable joining without soldering.

Installation Note

Apply approved thread sealant or PTFE tape during installation to ensure optimal sealing performance. Thread engagement should follow manufacturer torque guidelines to prevent overtightening and preserve thread form.
