ABS Blind Flange
The ABS Blind Flange is a robust, disc-shaped fitting designed to close the end of a piping system or pressure vessel securely. Manufactured from Acrylonitrile Butadiene Styrene (ABS), it offers a lightweight yet durable solution for non-corrosive, low-pressure industrial applications. Ideal for systems that require periodic inspection, maintenance, or future expansion, this blind flange ensures a reliable, leak-proof seal when paired with the correct gasket and bolts. Resistant to corrosion, impact, and a wide range of chemicals, ABS blind flanges are widely used in water treatment, marine, cooling systems, food and beverage, and chemical handling industries.
ABS Blind Flange
