1 inch x 3/4 inch Stainless Steel Reducing Coupling Female x Female

1" x 3/4" Stainless Steel Reducing Coupling – Industrial-Grade Transition Fitting

The 1" x 3/4" Stainless Steel Reducing Coupling is manufactured to provide a secure, corrosion-resistant solution for reducing pipe diameter in pressurized or mechanical systems. Its full-threaded female connections ensure a tight seal between dissimilar pipe sizes in both commercial and industrial plumbing applications.

Performance-Driven Features

• ✅ Material Grade: Fabricated from 304 or 316 stainless steel, providing excellent resistance to rust, chemical corrosion, and thermal variation.
• ✅ Connection Profile: Female National Pipe Thread (NPT) on both ends, allowing for secure threaded joints without welding or soldering.
• ✅ Reduced Coupling Body – Allows direct connection between 1" and 3/4" nominal pipes, eliminating the need for multiple fittings.
• ✅ Pressure Rating: Suitable for use in systems up to 150 psi, depending on piping layout and fluid type.

Technical Specifications

• Connection Size: 1" Female NPT x 3/4" Female NPT
• Material: 304/316 Stainless Steel
• Operating Temperature Range: Up to 400°F depending on pressure and media
• Compliant Standards: Meets ASME B16.11 and ASTM A182 requirements

Installation Notes

Apply PTFE thread sealant or approved pipe dope to male threads before assembly. Hand-tighten followed by an appropriate number of wrench turns per torque specifications to prevent thread galling and maintain joint integrity. Avoid over-tightening to reduce the risk of cracking the fitting under load.

Application Areas

• • Process piping in food-grade or pharmaceutical production
• • Potable water distribution systems
• • HVAC hydronic loops and pressure-regulated lines
• • Chemical and oil transfer systems where corrosion resistance is critical

Did You Know?

Stainless steel fittings outperform brass or galvanized alternatives in aggressive environments, especially where exposure to chlorides or temperature cycling is a concern.

The 1" x 3/4" Stainless Steel Reducing Coupling is a high-performance solution for reducing line size while preserving pressure integrity. Its precision machining and robust construction make it an essential component for contractors requiring long-lasting, code-compliant fittings in demanding environments.
