High-Performance End Cap for 4" RO Membrane Housings
The Stainless Steel (SS) 4040 Membrane Housing End Cap is a precision-engineered component designed for 4-inch (4040) RO membrane housings. While the housing body is made of stainless steel, the end cap is manufactured from high-strength engineered plastic/FRP material to ensure reliable sealing and efficient performance.
This design provides a perfect balance of durability, corrosion resistance, and ease of installation, making it ideal for commercial and industrial RO systems.

❓ How it works
The end cap seals the membrane housing, allowing pressure to build inside the vessel for reverse osmosis.
It works with O-rings to:
- Prevent water leakage
- Maintain internal pressure
- Ensure proper water flow through the membrane
This helps achieve efficient filtration and protects membrane performance.
