Waterway Suction Cover VGB, 5" Super Hi-Flow, Grey, W/O Screws (642-3637 V)

Introducing the Waterway Suction Cover VGB, a 5" Super Hi-Flow grey suction cover designed to optimize pool water movement without compromising safety. This Waterway part is built to deliver strong turnover while fitting securely into standard inlets, making it a dependable choice for both retrofits and new installs.

Two clear flow configurations to match your system
- With vacuum tube: 232 gpm
- Without vacuum tube: 180 gpm

The cover diameter is 5-3/16", providing a precise fit for Waterway suction fittings and helping ensure a reliable seal when mounted with your existing hardware. Note that screws are not included, so you’ll need to supply mounting hardware compatible with your pool wall and flange setup.

Key benefits that matter in real-world use

• High-flow performance. The 232 gpm capability with the vacuum tube supports higher turnover, making it a strong choice for larger residential pools, multi-zone setups, or spa-like features where rapid circulation is desired.
• Versatile flow options. The option to operate at 180 gpm without the vacuum tube gives you flexibility for systems where maximum flow isn’t necessary or where tubing isn’t present.
• Precise sizing for reliable fit. The 5-3/16" diameter ensures compatibility with standard Waterway inlet openings, helping maintain a tight, water-tight seal when correctly installed.
• Distinctive grey finish. The neutral grey color blends with most pool interiors and equipment, helping the cover stay discreet while performing its job.
• Simple replacement path. For ongoing maintenance or upgrades, swapping in this Waterway cover can restore flow characteristics and keep your system performing as intended.

Ideal applications
Residential and commercial pools undergoing renovation or new construction where high-flow capability is a priority. This cover is well-suited for systems that rely on the vacuum tube configuration to maximize gpm, or for setups that operate effectively at a lower flow without the tube.

Practical notes for installation
- Confirm your inlet opening is compatible with the 5-3/16" cover diameter. Measure the existing opening if you’re replacing an older cover.
- Screws are not included—choose corrosion-resistant mounting hardware appropriate for your pool wall and surface type.
- If your system uses a vacuum tube accessory, installing this cover will enable the higher 232 gpm flow; without the tube, you’ll achieve around 180 gpm.
- This is a Waterway-branded suction cover designed to integrate with Waterway components and standard pool plumbing configurations.
