Holyoke Fittings 41fpsw-6 3/8 Inches Swivel Forged Flare Nut

Product Description

The Holyoke Fittings 41fpsw-6 is a 3/8 inches swivel forged flare nut designed for use across a wide range of trade and industrial applications. This fitting is built for professionals who need a reliable, leak-free connection at refrigerant lines, fuel gas lines, or fluid transfer tubing. The swivel design allows the nut to rotate freely during installation, which reduces torque stress on the connected tubing and makes it easier to achieve a clean, tight seal without twisting the line itself. This is especially useful in tight spaces where conventional fixed flare nuts are difficult to seat properly.

Forged construction sets this nut apart from cast alternatives. The forging process aligns the metal grain structure, resulting in greater tensile strength and resistance to pressure cycling, vibration, and temperature swings. For HVAC technicians working with refrigerant lines, plumbers handling LP gas connections, or mechanics routing fuel lines, that added durability matters over the long service life of a system.

The 41fpsw-6 is compatible with 3/8 inches outside diameter tubing and fits standard flare fittings used throughout the air conditioning, refrigeration, plumbing, heating, automotive, and industrial sectors. It is a genuine OEM product, new and ready to install. Holyoke Fittings has a long-standing reputation in the fluid and gas fitting market, and this part reflects that quality. Whether you are replacing a worn nut on a refrigeration unit, completing a new LP gas installation, or making a repair on an automotive fuel system, this forged swivel flare nut delivers the performance and fit that trade professionals depend on.

• Swivel design rotates freely to reduce installation torque and protect tubing from twist damage
• Forged construction provides superior strength and durability compared to cast fittings
