Reliable Ductile Iron Grooved Concentric Reducer for Fire-Fighting

Direct Groove-to-Thread Transition: Combines a grooved end and a precision threaded end into one concentric reducer, ensuring a leak-free, perfectly centered size transition.

Eliminate Multi-Adapter Costs: Stop buying separate grooved reducers and threaded nipples to adapt your lines; our all-in-one component handles the size and connection transition in one step.

50% Fewer Leak Points: Replacing a multi-piece assembly with a single factory-cast component slashes potential system leak paths and field assembly time by 50%.

Equipment & Valve Tie-Ins: Ideal for transitioning from large grooved main water lines to smaller threaded control valves, pressure meters, or drainage outlets in compact commercial mechanical rooms.

Zero Heat Distortion: Unlike welding a threaded adapter onto a reduced pipe-which destroys internal anti-corrosion linings-our cold-formed design preserves 100% factory coating protection.

Fusion-Bonded Epoxy Finish: Electrostatic paint line delivers a smooth, scratch-resistant red shell that fights heavy rust and scale.

High-Toughness Ductile Iron: Cast from grade QT450-10 ductile iron with precision wall thickness to resist water hammer impacts safely.

Palletized Edge Protection: Secured on heavy wooden pallets with rigid edge guards, ensuring pristine coatings upon delivery.

Smooth Pipeline Reduction: Transitions different pipe diameters instantly while preserving fluid velocity and flow efficiency.

Shock-Absorbing Over Welded Reducers: Unlike rigid welded reduction joints that snap under building stress, grooved reducers absorb structural settlement.
