Value Brand Reducing Sanitary Tee 4 in x 3 in Hub Schedule 40

SKU CH-A6G3-FCEQ2

Reducing sanitary tee connects 4 in and 3 in ABS pipes with hub ends, meets ASTM D3965 cell class 32222, rated to 180 °F, Schedule 40

  • Reduces pipe diameter smoothly with 4 in x 3 in hub configuration
  • Meets ASTM D3965 cell class 32222 for reliable drainage performance
  • Withstands temperatures from -40 °F to 180 °F for year-round use
  • Schedule 40 wall thickness handles standard residential pressure loads
  • ABS material resists corrosion and chemical attack in waste systems

Reducing Sanitary Tee Hub Connection

This reducing sanitary tee joins three hub connections in a single ABS fitting. The 4 in by 4 in by 3 in layout connects a smaller branch line to a larger main run for drainage, waste or vent systems. It is intended for plumbers and contractors assembling non-pressure sanitary piping.

Schedule 40 ASTM D3965 Temperature Limits

The fitting meets Schedule 40 dimensions and complies with ASTM D3965 cell class 32222. Its rated service range spans -40 degrees to 180 degrees F, so it suits standard residential and commercial drainage temperatures. It is not rated for pressurised supply lines or temperatures outside this window.

Replaces Glued Hub Tees in ABS Systems

This tee replaces field-fabricated hub assemblies when a clean, code-compliant reduction is required. The jump is worth it when the installer needs a single factory-moulded fitting that eliminates extra couplings and reduces potential leak paths in new or remodelled ABS drainage networks.

Questions about this item

Should I choose the 4 in x 3 in hub version for my drainage stack?

This reducing sanitary tee is sized 4 in x 4 in x 3 in with hub connections on all three outlets, matching a 4-inch main line that steps down to a 3-inch branch.

How does the temperature range affect performance in a real installation?

The fitting is rated for continuous use from -40 °F to 180 °F, so it handles cold-weather exposure and hot wastewater without softening or cracking.

What does the ASTM D3965 cell class 32222 cap in practice?

Cell class 32222 defines the ABS material’s minimum impact strength, stiffness and heat-distortion limits, ensuring the Schedule 40 wall meets code requirements for drain, waste and vent systems.
