Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these fittings in a low-pressure pipe line.

Straight Connectors

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.

Premium Low-Pressure Stainless Steel Threaded Pipe Fittings

Unlike other stainless steel fittings, these are cast in the U.S. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition. All fittings except plugs adhere to ANSI/MSS SP-114 standards for heat treating, material thickness, and marking. It’s the highest quality standard for Pressure Class 150 low-pressure stainless steel fittings. They also meet either ASTM A351 or A479 requirements for parts that will be used in pressure systems. These stainless steel fittings are more corrosion resistant than steel fittings, and almost as strong.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
