Atlas PVC Socket 90mm × 3", Step Coupling, Solvent-Weld, Reduced Turbulence

Material: sturdy PVC. Size: 90mm to 3" transition. Ends: solvent-weld for durable joints. Features: corrosion-resistant body, smooth bore for reduced turbulence, and suitability for medium to high-pressure systems. It’s designed for quick, reliable installations and cost-effective performance.

This step coupling specifically provides a metric-to-imperial transition with a smooth bore to minimize turbulence, while offering a solvent-weld connection for leak-free performance. It’s optimized for retrofit and cross-standard projects, whereas a standard socket usually stays within a single pipe standard.

Ideal for manifold upgrades, irrigation and filtration connections, and mixed-standard retrofits where 90mm metric piping needs to couple with 3" imperial PVC. It’s also well-suited for pump rooms, farms, and treatment skids in coastal or high-cleaning environments.

Prepare surfaces per PVC cement guidelines, dry-fit to ensure alignment, then apply compatible PVC primer and cement to both ends. Insert and twist gently to create a secure bond, wipe away excess cement, and allow the joint to cure fully before pressurizing the system. Always ensure the system is depressurized and clean before installation.

Wear eye protection and gloves when handling PVC cement and primers. Work in a well-ventilated area to avoid inhaling fumes. Follow all product-specific safety data on the cement, and ensure the pipe system is depressurized before starting work.

Yes, it can be used outdoors. The body is corrosion-resistant and designed to withstand outdoor conditions, but for extended outdoor exposure, consider applying external UV protection or housing to maximize service life.

It is designed for a 90mm metric pipe to 3" imperial pipe. Verify compatibility by checking the wall thickness and schedule of your pipes and ensuring compatible socket dimensions. When in doubt, compare with the system’s standard fittings and ensure a proper solvent-weld joint for a leak-tight connection.

Upgrading a manifold where metric piping needs to connect to imperial equipment, tying together site mains with imported components, or retrofitting existing systems to accommodate mixed pipe standards while preserving smooth flow and leak-free joints.

First depressurize the system and re-clean the pipe ends. Re-apply primer and solvent cement as per the guidelines, reinsert, and ensure a full, uniform bond. Check for any misalignment and confirm that both ends are properly prepared before pressurizing again.

It provides a durable, leak-tight, solvent-weld connection with a smooth bore that reduces turbulence, which can lower maintenance costs and improve flow efficiency over time. The upfront investment in a purpose-built metric-to-imperial adapter often pays off through fewer leaks and easier retrofits in mixed-standard systems.
