⚙️ Built for Tough Industrial Environments
-
Innovative U-Shaped Ball Design: Eliminates vulnerable metal springs! Uses fluid weight for an absolute seal. Can be installed HORIZONTALLY or VERTICALLY with superior backflow prevention.
-
Precision Rib Guides & Reinforced Seal: Internal ribs perfectly guide the half-ball, while a support ring prevents the sealing gasket from deforming under extreme 150 PSI pressures.
-
Lathe-Machined Surfaces: The contact surfaces are precision lathe-machined for absolute flatness, guaranteeing a flawless seal for corrosive liquids and high-pressure water lines.
-

⚠️ Sizing & Connection Guide (Crucial!)
-
🚨 SIZING LOGIC (Inner Dia. matches Outer Dia.): The sizes listed (e.g., 110mm) refer to the Inner Diameter (I.D.) of the socket. They sleeve OVER matching PVC pipes.
