Description
The Rapidrop 1NR Standard Reducing Flexible Coupling (6″ x 4″ / 150 ? 100 mm) is a premium mechanical joint designed to transition between a 6-inch (150 mm) pipe and a 4-inch (100 mm) pipe without requiring a separate concentric reducer fitting. Constructed from high-strength ductile iron with a corrosion-resistant red finish, this flexible coupling features an engineered, contoured EPDM gasket that ensures a completely leak-tight seal across both pipe diameters. This component allows for intentional controlled linear and angular movement in the pipeline to alleviate structural stress. It safely supports a maximum working pressure of up to 300 PSI (20.7 bar) and is UL Listed and FM Approved, ensuring top-tier safety and durability in demanding fire protection and industrial piping networks.
Features
- Direct Size Reduction: Combines a pipe size transition and a secure joint into a single component, eliminating the need for a separate reducing fitting.
- Flexible Piping Integration: Designed to absorb thermal expansion, contraction, and seismic movement while minimizing vibration transfer through the line.
- Leak-Proof Performance: Outfitted with a specialized EPDM gasket engineered to maintain a durable, long-term seal on both pipe sizes.
- High-Strength Build: Formed from heavy-duty ductile iron to withstand demanding physical impacts and high operational pressures.
- Fast and Cost-Effective Assembly: Speeds up line construction and cuts down on-site labor and material costs compared to traditional welding or threading.
