Sealing Flange

Stainless steel sealing flanges are designed to create a clean, reinforced sealing point around tube penetrations or tube-to-surface connections. They are commonly used where a finished flange face is required to securely mount, seal, or fix a tube assembly into panels, tanks, vessels, or other fabricated components. By providing a defined seating surface, sealing flanges help improve stability, alignment, and sealing performance while delivering a professional, finished appearance.

This range of sealing flanges is manufactured from Grade 316 stainless steel and supplied in a satin finish. Grade 316 stainless steel is highly regarded for its excellent corrosion resistance, particularly in environments exposed to moisture, salt, chemicals, and frequent wash-down. This makes these sealing flanges especially suitable for coastal and marine installations, chemical processing equipment, and hygienic applications such as food and beverage production. The satin finish offers a smooth, uniform appearance that is easy to clean and visually consistent with other stainless steel components, making it ideal for architectural and exposed installations.

Sizes are listed in millimetres and cover a wide range of commonly used tube diameters, allowing easy matching to standard stainless steel tube systems. This flexibility makes sealing flanges suitable for a variety of fabrication and installation requirements, from small service penetrations to larger structural or process connections. They are widely used in stainless steel fabrication, food and beverage equipment, marine fit-outs, tanks and vessels, and architectural projects where both function and appearance are important.

By reinforcing tube penetrations and providing a reliable sealing surface, stainless steel sealing flanges help improve durability, reduce wear, and support long-term performance. For applications requiring a corrosion-resistant, hygienic, and visually clean mounting or sealing solution, 316 stainless steel sealing flanges offer a proven and industry-standard choice.
