This 4-pack of screws is designed specifically for mounting standard reverse osmosis (RO) filter housings to their corresponding brackets. These essential fasteners ensure that your filter housings are held firmly in place, preventing movement or vibration that could lead to leaks or damage to your water purification system. They are the ideal replacement for lost, stripped, or corroded original screws, restoring the stability and safety of your RO/DI unit.

Each screw measures 3/16 inches in diameter and 3/4 inches in length, providing the perfect dimensions for a secure fit on most common RO housing and bracket combinations. The Phillips head design allows for quick and easy installation using a standard screwdriver, making maintenance or initial setup a straightforward process. This convenient pack of four provides enough screws for a single housing with spares or for mounting multiple housings.

This product is perfect for any saltwater aquarist who is building a new RO/DI system from individual components, performing routine maintenance, or repairing an existing unit. Having these specific screws on hand ensures you can properly secure your filter housings, which is critical for the long-term, leak-free operation of your water purification setup. They are an indispensable small part for maintaining the heart of your pure water source.
