Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Low-Pressure Stainless Steel Threaded Pipe Fittings
Straight Adapters
 |
Female × Butt Weld |
Threaded Fitting Connection—Threaded female x butt weld straight adapters are also known as half couplings.
304 Stainless Steel—Fittings hold up in humid, damp, and washdown environments but will corrode if exposed to salt water or chemicals.
316 Stainless Steel—Fittings are the most corrosion resistant. They stand up to wet environments, just like 304 stainless steel fittings, but unlike 304 stainless steel, they will not corrode from salt water, chlorine solutions, and chemicals.
