Rubber Cap for Distribution Manifolds
Rubber Cap for Distribution Manifolds
The rubber cap is a sealing element designed to hermetically close unused ports on distribution manifolds and diffuser boxes. It prevents air leaks into the ceiling void through open outlets, maintaining stable and calculated working pressure throughout the entire ventilation system.
Unlike standard rigid plastic covers, which often serve only as temporary protection against construction dust, this part is made of a premium elastomer and features a unique design. A rigid honeycomb structure is molded inside the elastic body. This hybrid design allows the soft edges to tightly grip the port, while the internal frame solidly holds the cap's shape, preventing it from bulging or vibrating under high air pressure.
Key Features and Benefits
- Push-fit installation: Thanks to the elastic material, the part is simply pushed into place with a snug fit. It is self-sealing, completely eliminating the need for messy silicone or wrapping the joint with meters of aluminum tape.
- Resistance to high pressure: The internal stiffening ribs (honeycomb) absorb the aerodynamic load. Even when the heat recovery unit's fans are operating at maximum capacity, the cap will not flutter or blow out of the manifold.
- Guaranteed aerodynamic integrity: The soft rubber edges perfectly adapt to the geometry of the port, providing 100% protection against micro-leaks and preventing any loss of system performance.
- Perfect compatibility: The part is designed specifically for the ports of modern manifolds that are conceptually based on reliable, tape-free rubber connections.
