Stainless steel fittings connect, redirect, or change flow in pipe systems. Engineers value them for corrosion resistance, durability, and high-pressure tolerance. Common types include elbows, tees, and couplings. Industries such as food, chemical, and pharmaceutical widely use these fittings. They provide strength, longevity, and minimal maintenance requirements. Grades 304 and 316 stainless steel remain the most popular choices for applications.
