1. Specifications
-
Material
Stainless Steel Grades:
304/304L stainless steel provides good corrosion resistance for pipe coupling.
316/316L stainless steel decay resistance properties are better than ss 304 couplings.
-
Standards
We manufacture ASTM A865 coupling, ASME B1.20.1, DIN2986, EN10241, and more.
-
Size
Except with a nominal diameter of 1/2 inch coupling, we also produce 1/8 to 12-inch pipe coupling to satisfy different needs.
-
Coupling Type
Typically available in various types, including:
NPT coupling, BSPT coupling, BSPP coupling.
And socket weld coupling and butt weld coupling are suitable for high-pressure applications.
-
Threaded Couplings
Thread Type:
The threaded coupling connects pipes with female threads.
NPT pipe thread, BSPT thread standard, BSPP thread.
Thread Standards:
DIN2999, ISO 7-1 or BS21.
-
Pressure Ratings
Pipe coupling usually can withstand 20.7 bar, typically up to 300 psi.
2. Applications

1/2 coupling is suitable in industrial applications where corrosion resistance is crucial.
1/2 stainless steel pipe coupling is used widely in multiple industries and environments due to its small size and superior decay resistance, including:
Plumbing
HVAC systems
Both water, oil, and gas lines
Chemical and Pharmaceutical Industry
Industrial manufacturing equipment
Residential and commercial buildings, etc.
3. Features

The 1/2 coupling uses high-quality material, 304 and 316 stainless steel, which is durable and resistant to rust and corrosion.
A pipe coupling is easy to install and remove.
NPT, BSP thread coupling, and socket weld can chosen.
1/2 coupler leakproof, hygienic.
4. Finish
Polished, let pipe coupling safety when used in medical applications and food processing.
5. Where to Buy Stainless Steel Coupling
In our factory, we are a Hebei SANVO pipes and fittings supplier, and we can manufacture a series of couplings and other fittings, not only 1/2 inch coupling. You can contact us to customize the size to ensure compatibility with your existing piping system or project.
