Atlas PVC Flange Single Set 4", Bolted Connection, Maintenance-Friendly, Flat-Face

The set is made from durable PVC, sized to fit 4-inch PVC pipes, and includes a complete flange assembly with a gasket and fasteners. It’s designed to be corrosion-resistant, leak-proof, and capable of withstanding typical piping system pressures while being easy to install.

The package includes the 4" flange plates, a gasket, and the necessary bolts and nuts for a bolt-up connection, ensuring you have all parts needed for a hassle-free installation.

PVC fittings can degrade with prolonged sun exposure. For outdoor or high sun exposure, use a UV-resistant coating or shielding to extend the life of the flange set and maintain performance.

Basic steps: (1) inspect and clean the flange faces and pipe ends, (2) place the gasket between the flange faces, (3) align the flange holes, (4) insert bolts and tighten in a crisscross pattern to ensure even seating, (5) check for leaks after assembly, and (6) avoid overtightening to prevent gasket damage. Use appropriate PPE and follow standard piping practices.

The flange is designed for reliable performance in typical piping installations and is described as pressure-resistant within its intended PVC applications. For very high-pressure systems, verify compatibility with your specific operating pressure and consider appropriate safety margins.

It’s well-suited for equipment tie-ins, temporary bypass headers, or connections that require periodic removal. It’s particularly handy for projects in coastal or humid environments where corrosion resistance is important.

The 4" version matches 4-inch PVC piping needs and larger flow paths, making it more suitable for bigger equipment or higher flow points. If you’re choosing between sizes on Fepy, compare the pipe diameter, gasket compatibility, and bolt pattern to ensure a proper match with your system. For a closer size comparison, see the Atlas PVC Flange Single Set 3 Inch and other 4" variants on Fepy to understand differences in fit and performance.

Compare gasket material, bolt patterns, and whether UV protection is included.

Regularly inspect the flange for signs of leakage or corrosion (even though PVC is corrosion-resistant). Ensure bolts remain snug, check gasket seating periodically, and protect the assembly from prolonged direct sun exposure with UV shielding. Use compatible gasket material for your fluids and follow standard safety practices for chemical handling and piping systems.

Atlas 4" PVC flange sets are designed for ease of installation, corrosion resistance, and maintenance-friendly bolt-up connections. The included complete set simplifies procurement, and the imperial sizing matches imported equipment common on UAE projects. When evaluating, consider material compatibility, ease of installation, available sizes, and how well the bolt pattern and gasket fit your system.
