Harry Fittings, based in Houston, USA, is a well-respected manufacturer and supplier of top-quality Monel K500 Forged Fittings, crafted for outstanding performance in tough, corrosive, and high-pressure settings. Monel K500 is a nickel-copper alloy that gains extra strength and hardness through age-hardening, making it perfect for demanding tasks. Harry Fittings offers a full lineup of forged fittings—like elbows, tees, couplings, unions, and plugs—that meet ASTM B564, ASME B16.11, and other global standards. These fittings are commonly found in marine, chemical, oil & gas, and aerospace industries, where top-notch corrosion resistance and mechanical strength are essential.

Monel K500 Forged Fittings from Harry Fittings are primarily made up of nickel (63%) and copper (27–33%), with small amounts of aluminum (0.3–0.8%) and titanium (0.35–0.85%) added for age-hardening. This combination results in impressive tensile strength (~965 MPa) and yield strength (~690 MPa), which are significantly higher than standard Monel 400, while still offering excellent corrosion resistance in seawater, acidic, and alkaline conditions. These fittings hold their strength at temperatures up to 480°C and are resistant to stress-corrosion cracking and pitting. Each fitting is manufactured with precision and rigorously tested for hardness, pressure resistance, and dimensional accuracy.
