## Summary description

SpiroFlex Mufa PVC DN75 is a PVC pipe coupling designed for connecting pipes with a 75 mm nominal diameter (DN75). It provides a simple mechanical joint for plumbing and drainage systems made from PVC, suitable for repairs or new installations where a straight connector is required. Typical uses include sewer, stormwater, and building drainage applications.

## Long description

SpiroFlex Mufa PVC DN75 is a straight PVC coupling designed to connect two pipes with a nominal diameter of 75 mm (DN75). The coupling provides a mechanical joint appropriate for plumbing and drainage systems made from PVC and is suitable for repair work or new installations where a robust, inline connector is required. The product is intended for use in sewer, stormwater, and building drainage applications and is compatible with standard 75 mm PVC pipes.
Advantages
The coupling offers a simple, durable connection that is resistant to corrosion and chemical exposure typical in drainage environments. Its PVC construction ensures low weight and ease of handling during installation. The straight design minimises flow disturbance and supports reliable sealing when used with compatible gaskets or solvent welding methods. The product requires minimal maintenance and provides a cost-effective solution for joining pipes of the same nominal diameter.
Suitable for
Repairing broken or leaking 75 mm PVC drainage lines
Joining sections of sewer or stormwater piping in buildings
Inline connections in above-ground or accessible underground drainage systems
Key specifications
Material: PVC (polyvinyl chloride)
Nominal diameter: 75 mm (DN75)
Design: straight coupling for inline connection
Application: gravity drainage — sewer, stormwater, building drainage
Surface: smooth bore to promote unobstructed flow
How to use
Select a coupling that matches the outer diameter of the existing pipes and prepare pipe ends by cleaning and deburring to ensure a smooth fit. For push-fit installations, insert the pipe ends into the coupling until they reach the internal stop, and ensure any gasket or sealing element is correctly seated. For solvent-welded joints, apply the appropriate PVC primer and solvent cement following the adhesive manufacturer’s instructions, then assemble and hold until the joint sets. Allow any adhesive or seal to cure for the recommended time before placing the pipe back into service. Verify alignment and test the joint for leaks after installation.
Usage recommendations
Use compatible seals or approved solvent adhesives suitable for PVC materials and rated for drainage applications. Avoid exposing the coupling to sustained mechanical loads or temperatures beyond PVC material limits. Inspect joints after installation and periodically during service for signs of wear, deformation, or leakage.
