The MECCANIXITY Rubber Flange Gasket provides a reliable, full‑face seal for 3‑inch (DN65) pipe connections. Constructed from a durable black rubber compound, the flat washer fits between two pipe sections or valve flanges, preventing leakage and keeping the joint from flaring under pressure. Its four precisely‑drilled bolt holes ensure secure fastening, and the gasket’s corrosion‑resistant formulation stands up to harsh chemicals and aggressive environments.

Designed for a wide operating envelope, this gasket tolerates temperatures from –40 °C to 230 °C (–40 °F to 446 °F) and pressures below 0.05 MPa, making it suitable for many industrial and commercial piping systems. Installation is straightforward: align the bolt holes, place the gasket between the mating surfaces, and tighten with a torque wrench (not included) to achieve a leak‑free seal. Always verify the dimensions required for your application before purchase.
