Low-Pressure Stainless Steel Threaded Pipe Fittings

Use these fittings in a low-pressure pipe line.

Hex-Drive Plugs

Magnetic—Plugs with magnet attract metal debris that could otherwise damage your system.

NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.

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 Medium-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 adhere to ANSI/MSS SP-114 standards for heat treating, material thickness, and marking. It’s the highest quality standard for Pressure Class 1000 medium-pressure stainless steel fittings. 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.

Low-Pressure Galvanized Iron and Steel Threaded Pipe Fittings with Sealant

The male threads on these fittings have a sealant applied for extra leak protection. Fittings are made of galvanized iron or steel, which have fair corrosion resistance. Also known as Pressure Class 125 or 150 fittings, they are for use in low-pressure applications.

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.

Universal-Thread Medium-Pressure Brass and Bronze Threaded Pipe Fittings

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT). Made of nickel-plated brass, they resist corrosion better than plain brass fittings. A reusable Buna-N O-ring protects against leaks. Connectors, adapters, and reducers all have a hex-shaped body, so you can tighten them with a wrench.

High-Pressure Iron and Steel Threaded Pipe Fittings

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

Note: The maximum pressure listed for Class 3000 fittings is for conditions where there are no sudden changes in pressure or velocity. Please refer to ASME B16.11 to determine the specific maximum operating pressure for your application.
