Ashirvad Flowguard Plus CPVC Reducer Coupler

Ashirvad Flowguard Plus CPVC Reducer Coupler enables seamless transitions between different pipe sizes in CPVC plumbing systems. This precision-molded fitting features two socket connections of different diameters, allowing you to reduce from a larger main line to a smaller branch or fixture supply line. The gradual internal taper ensures smooth water flow without turbulence or excessive pressure drop at the transition point.
Manufactured from high-grade CPVC compound with FlowGuard Gold technology, this reducer coupler maintains full pressure rating across both socket sizes. The fitting is essential for optimizing pipe sizing throughout a plumbing system, using larger pipes for main distribution and smaller pipes for individual fixtures to balance flow rates and material costs. Compatible with all Ashirvad Flowguard Plus CPVC pipes when installed with recommended solvent cement.

Recommended Applications

Main to Branch Reduction: Reducing from 25mm main line to 20mm or 15mm branch lines for individual fixtures

Fixture Supply Lines: Transitioning from larger distribution pipes to smaller fixture connection sizes

Flow Optimization: Balancing flow rates by using appropriate pipe sizes for different sections

Geyser Connections: Reducing pipe size from main hot water line to individual geyser connections

Multi-Fixture Distribution: Creating properly sized branch lines from main distribution pipes

Renovation Projects: Connecting new smaller pipes to existing larger diameter systems

Installation Guidelines

Pipe Preparation: Cut both pipes (different sizes) squarely; deburr and chamfer each pipe end at 10-15? angle

Size Verification: Verify correct reducer coupler size matches your pipe diameters (e.g., 3/4″ x 1/2″ for reducing 3/4″ to 1/2″)

Dry Fit Check: Insert both pipes into respective sockets to verify proper fit before cementing

Solvent Cement Application: Apply Ashirvad CPVC solvent cement to both pipe ends and corresponding sockets; insert pipes with quarter turn and hold for 30 seconds each

Curing & Testing: Allow 24 hours curing time before pressurizing; verify no leaks at either connection
