Bd Manufacturing SPT655 Reducing Tee 1-1/4x1x1 Socket Fusion Sdr 11

Product Description

The BD MANUFACTURING SPT655 is a polyethylene reducing tee fitting designed for socket fusion piping systems. Built to PE4710 material specification and rated SDR 11, this fitting connects a 1-1/4 inch run to a 1 inch branch using socket fusion joints on all three ends. It is used in buried or above-grade PE piping systems where a flow reduction or branch takeoff is required. Licensed plumbers and pipefitters install this fitting using standard socket fusion tooling. The SDR 11 wall ratio provides a consistent pressure rating across the fitting and matched pipe.

This reducing tee is suited for residential and light commercial applications involving polyethylene piping, including water service lines, geothermal loop systems, and irrigation distribution mains. The socket fusion end connections allow for clean, heat-fused joints that produce a continuous, leak-free polyethylene bond. It is commonly installed in new construction and system expansion work where a run of 1-1/4 inch pipe transitions to a 1 inch branch.

Key Features

• PE4710 polyethylene construction for high-density, pressure-rated performance
• SDR 11 wall thickness ratio for consistent system pressure ratings
• Socket fusion connections on all three ends for heat-fused, solvent-free joints
• Reducing configuration: 1-1/4 inch run x 1 inch branch
• Suitable for buried and above-grade PE piping installations

Compatibility

Designed as an OEM-style replacement and standard fitting for SDR 11 PE4710 polyethylene piping systems using socket fusion joining methods.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter familiar with polyethylene socket fusion procedures. The piping system must be depressurized and drained before any fitting work begins. Proper socket fusion tooling, including a fusion iron and appropriately sized sockets, is required to achieve a rated joint. Follow applicable local plumbing codes and manufacturer fusion temperature and dwell time guidelines for PE4710 material.
