Our Galvanised Roll Groove Concentric Reducer UL/FM is a high-quality pipe fitting engineered for grooved piping systems, especially in fire protection and sprinkler installations. Made from ductile iron conforming to ASTM A536 Grade 65-45-12, designed to AWWA C606 standards, and finished with hot-dip galvanising for excellent corrosion protection. It carries UL and FM approvals for fire-sprinkler use.
Product Overview
This concentric reducer provides a secure and efficient way to reduce pipe diameter while maintaining the same centre‐line. With roll-grooved ends, it enables fast installation with grooved couplings, eliminating the need for welding or flange connections in many cases. Ideal for fire-sprinkler, HVAC and water distribution systems.
Construction & Design
The body is crafted from high-strength ductile iron to ASTM A536 Grade 65-45-12. The roll-grooved ends are manufactured to match standard grooved coupling specifications. The hot-dip galvanised finish ensures durability and corrosion resistance in wet or exposed environments. Approved for working pressures up to approximately 300 psi (≈ 2 100 kPa) depending on size.
Key Features and Benefits
UL & FM Approved: Certified for fire protection applications, giving you assurance of quality and compliance.
Hot-Dip Galvanised Finish: Superior corrosion resistance for long service life in wet or outdoor installations.
Roll-Grooved Ends: Quick and efficient installation using grooved couplings — saves labour versus welding or flanging.
Concentric Design: Maintains pipe centre-line when reducing diameter, ideal for system alignment and flow continuity.
High Pressure Rating: Suitable for use up to ~300 psi (≈2.1 MPa) depending on size — fits many fire-sprinkler and industrial systems.
Wide Size Range: Available in various combinations (e.g., 65 × 50 mm, 100 × 80 mm, 150 ×100 mm etc) to fit many pipe transitions.
