Material: Rigid PVC for corrosion resistance and long service life. Connection: Insert x Insert (insert fittings on both ends for easy push-in installation). Size: Reduces from 1-1/2" to 3/4" — common for branch connections and repair work. Applications: Irrigation, drip systems, pool plumbing, and general-purpose water lines. Installation: Simple insert-style assembly; recommended for use with proper barbed insertion and clamp or compatible adhesive where required. This reducing coupling (SKU 1429210) is a straightforward, cost-effective solution when you need to join different diameter insert-style tubing quickly and securely.
