Blue Devil B8550 Skimmer Weir Gate | Swimquip U3 | 8-3/8"

The Blue Devil B8550 Skimmer Weir Gate is designed for Swimquip U3 skimmer assemblies and uses an 8-3/8 inch float gate to regulate surface water entry into the skimmer. Its buoyant hinged design allows the gate to rise and fall with water movement, improving debris capture by directing leaves and surface contaminants into the skimmer basket while preventing debris from washing back into the pool. Built from durable plastic suitable for continuous water exposure, the weir gate helps restore proper flow and skimming efficiency in older or worn Swimquip U3 systems. Replacing a warped or broken gate improves circulation and supports more effective surface cleaning.

Highlights

• Fits Swimquip U3 Skimmers: Sized specifically for U3 skimmer bodies that require an 8-3/8 inch weir gate for correct operation.

• Buoyant Hinged Design: Opens and closes with water movement to guide debris into the skimmer and reduce backflow into the pool.

• Durable Construction: Made from strong, water-resistant plastic designed to withstand continuous exposure and pool chemistry.

• Restores Skimming Efficiency: Helps improve surface debris capture and overall circulation in older or worn Swimquip systems.

• Easy Replacement Part: Simple to install during maintenance, making it a practical solution when the original gate becomes warped or damaged.

Additional Info

The Blue Devil B8550 is a reliable 8-3/8″ replacement for Swimquip U3 skimmers commonly found on service routes. This section helps technicians verify fitment, confirm swing action and diagnose skimmer performance issues when sourcing through local suppliers.

Field Fitment Verification for Service Technicians

The precise 8-3/8″ width matches U3-style skimmers (including 08650-0022). Technicians can confirm fit by checking the throat opening or measuring the removed gate.
