Stainless Steel 304H Tube Fittings


Arrow Piping Solutions is one of the prominent manufacturers and exporters of SS 304H Compression Tube Fittings. SS 304H has a higher carbon content which makes it more suitable for high-temperature applications. Known as UNS S30409 and DIN 1.4948, this grade provides superior tensile strength, yield strength, and improved short- and long-term creep resistance.


Our SS 304H Compression Tube Fittings offer leak-proof connections and are highly durable in corrosive environments. These fittings are ideal for industries like oil refining, chemical processing, power plants, and instrumentation systems. We manufacture these products in-house under strict quality checks using high-end tools and premium raw materials.
