3/4-16 RH Tube End 1-3/4in x .120

The 3/4-16 RH tube end 1-3/4in x .120 from Meziere is a precision-engineered threaded fitting designed for high-performance cooling system fabrication and custom radiator hose applications. Built for serious engine builders, fabricators, and mechanics who demand OEM-quality results when constructing custom coolant lines, this right-hand thread component integrates seamlessly into modular cooling system designs where off-the-shelf hose configurations won't suffice. Whether you're assembling a vintage hot rod, fabricating a LS-swap cooling system, or engineering a custom water-cooling setup, this tube end provides the structural integrity and sealing reliability required in high-temperature, high-pressure environments.

Manufactured with precision 3/4-16 RH threading, this tube end accepts standard -16 AN hose barbs and compression fittings, ensuring compatibility with industry-standard cooling components. The 1-3/4-inch outer dimension and .120-inch wall thickness deliver robust structural performance under thermal cycling and vibration stress while maintaining a compact footprint ideal for tight engine bay installations. Meziere's attention to dimensional consistency—confirmed by the compact 2.15 x 1.8 x 3.6-inch package—ensures that tube ends seat flush against custom-fabricated tubing without requiring secondary machining or rework, saving fabrication time and reducing assembly errors during final system integration.

This component is ideal for mechanics and fabricators building custom radiator hose assemblies, nitrous systems, or modified cooling circuits where production hoses interfere with high-rise intake manifolds, turbocharger piping, or transmission oil coolers. The right-hand thread design ensures intuitive assembly without cross-threading during installation—critical when working in confined spaces where feel-based threading is your only reference. Weighing just 0.845 pounds, this lightweight fitting won't add unnecessary mass to your system while maintaining full pressure ratings up to 30+ PSI, making it equally suitable for street-driven restorations, track-focused builds, and daily-driver engine swaps that demand reliability without compromise.
