LEADING METAL GASKETS MANUFACTURER, EXPORTER & SUPPLIER
Manufacturer, Exporter & Supplier of Premium Industrial Gaskets
Precision manufacturers of industrial gaskets in Cupro-Nickel, Stainless Steel, Copper, Brass, Inconel, Monel & Hastelloy — trusted by engineers across oil & gas, marine, petrochemical, and process industries worldwide.
Sunflex Metalloy is a specialized manufacturer of high-performance industrial gaskets, committed to delivering sealing solutions that perform without compromise. Founded with a vision to serve industries where failure is not an option, we have built our reputation on metallurgical expertise, dimensional accuracy, and consistent quality across every product we manufacture.
From small-bore flanged connections to large-diameter pressure vessel assemblies, our gaskets are engineered to meet international standards and the exacting demands of our customers. We work closely with procurement teams, project engineers, and maintenance professionals to ensure the right material, right dimension, and right delivery — every time.
At Sunflex Metalloy, we specialize in the fabrication of industrial gaskets across four key metal families — each selected and processed for its unique mechanical and chemical properties. Whether your application demands corrosion resistance in aggressive marine environments, high-temperature strength, or reliable sealing under cyclic pressure loads, we have the material expertise and manufacturing capability to deliver.
Cupro-Nickel (Cu-Ni): The marine engineer's first choice. Cupro-Nickel gaskets offer superior resistance to seawater corrosion, biofouling, and stress corrosion cracking — making them the preferred choice for offshore platforms, shipbuilding, desalination plants, and coastal process facilities.
Stainless Steel: Strength where it matters most. Our stainless steel gaskets are engineered for high-pressure, high-temperature, and chemically aggressive environments. Available in SS 304, SS 316, SS 321, and duplex grades, they deliver long service life across petrochemical, pharmaceutical, and power generation applications.
Copper: Proven performance in heat-critical systems. Copper gaskets provide excellent thermal conductivity and malleability, creating reliable seals in heat exchangers, engine components, and flanged connections where a soft, conformable metal is essential for leak-free performance.
Brass: Dependable sealing for general industrial use. Brass gaskets combine good corrosion resistance with ease of machining, making them a cost-effective and reliable sealing solution for plumbing, water systems, HVAC, and general industrial assemblies.
Inconel: Built for the harshest environments, our Inconel gaskets are engineered to withstand extreme temperatures, oxidation, and high-pressure applications. Available in grades like Inconel 600, 625, and 718, they offer exceptional strength and corrosion resistance. Ideal for aerospace, chemical processing, and power generation industries, Inconel gaskets ensure reliability where failure is not an option.
Monel: Superior Resistance in Marine & Chemical Environments. Designed for durability in highly corrosive conditions, our Monel gaskets provide outstanding resistance to seawater, acids, and alkalis. Manufactured in grades such as Monel 400 and K500, they combine high strength with excellent corrosion resistance. Perfect for marine, oil & gas, and chemical processing industries, Monel gaskets deliver consistent performance and extended service life.
Hastelloy: Ultimate Protection Against Corrosion. Engineered for the most aggressive chemical environments, our Hastelloy gaskets offer unmatched resistance to oxidation, pitting, and stress corrosion cracking. Available in grades like Hastelloy C276, C22, and B2, they perform exceptionally well under high temperatures and extreme chemical exposure. Widely used in chemical processing, pharmaceuticals, and pollution control systems, Hastelloy gaskets ensure maximum safety and longevity.
When you source gaskets from Sunflex, you're not just buying a metal ring — you're partnering with a manufacturer who understands what's at stake in your application.
Precision Manufacturing: Precision at Every Dimension Every gasket we produce is manufactured to exact specifications with tight dimensional tolerances. Our production processes are built around accuracy — from inner bore to outer diameter to thickness — because in sealing applications, a fraction of a millimeter matters.
Multi-Material Expertise: Deep Material Knowledge We don't just cut metal — we understand it. With hands-on experience across Cupro-Nickel, Stainless Steel, Copper, Brass, Inconel, Monel and Hastelloy, we guide customers in selecting the right alloy for their operating conditions, ensuring maximum service life and sealing integrity.
Custom Fabrication: Made to Your Specification No two projects are identical. We offer fully custom gasket fabrication — any size, any thickness, any bore configuration — to match your flange standards, whether ANSI, DIN, BS, or non-standard OEM dimensions.
Reliable Supply: Consistent Quality, On-Time Delivery We understand that project timelines don't wait. Our manufacturing setup is designed for reliable, on-schedule dispatch, with thorough quality checks and material traceability on every order — from a single piece to a bulk contract.
