1-1/4" x 1-1/4" x 1/2" PVC Reducing Insert Tee (1401-166)

Durable PVC reducing insert tee engineered for polyethylene irrigation and potable water systems. This 1-1/4" x 1-1/4" x 1/2" fitting provides a secure, barbed insert connection designed to join polyethylene pipe with a reducing branch for smaller lines.

• Product size: 1-1/4" x 1-1/4" x 1/2" (Insert x Insert x Reducing Insert).
• Material: Rigid PVC body with barbed insert ends for reliable grip on polyethylene (poly) pipe.
• Connection type: Insert/barbed ends — push pipe onto barbs for a snug mechanical fit; use appropriate clamps for pressurized runs.
• Standards: Conforms to ASTM D-2609 and related insert fitting standards; many listings also note ASTM D-1784 material specs.
• Certifications: NSF-certified options available for potable water when sold as certified product; confirm certification for the specific unit purchased.
• Not for compressed air: Insert fittings are intended for liquid service — do not use for compressed air or gases.

Installation tip: ensure polyethylene pipe is cut square, deburred, and fully inserted to the recommended depth on the barb; secure with stainless steel or UV-rated clamps where system pressure or outdoor exposure requires added retention. This part (1401-166) is commonly stocked for irrigation, landscape, and potable water repair jobs where a reliable reducing branch is needed.
