Overview
The Victaulic R20 gasket is a precision sealing ring designed for 3″ OD pipes (88.9–89.1mm). This gasket is pressure responsive, providing increased sealing action as internal pressure rises, creating a permanent leak-tight triple seal across steel, stainless steel, aluminum, PVC, ductile iron, and copper piping. This product is essential for any facility running grooved coupling piping systems where reliable, maintenance-free sealing is critical.
Key Features
- Pressure-Responsive Design: Creates a pressure-responsive seal on the outside diameter of the pipe, enhanced as the coupling housing is tightened.
- Compatible with Multiple Pipe Materials: Works with steel, stainless steel, aluminum, PVC, ductile iron, and copper.
- Precision Molded: Molded to fit the internal cavity of the housing and positioned upon placement of the housing around the gasket into the grooves.
- Elastomeric Resilience: Resilient elastomeric gasket conforms to the internal cavity of the housing, enhancing the seal against the pipe in both pressure and vacuum conditions.
- Industry-Standard Quality: Subject to stringent quality control, precision engineering, and exhaustive testing before delivery.
