Williams Comfort Products 67034620670 Straight Tee 3 in

Product Description

The WILLIAMS COMFORT PRODUCTS 67034620670 is a 3-inch standard weld tee fitting manufactured to ASTM A234-WPB specifications. This butt-weld carbon steel tee is used to create branch connections in piping systems, splitting or combining flow in a straight-run configuration. The A234-WPB grade designation indicates wrought carbon steel material suitable for pressure piping service. Domestic manufacture supports traceability and compliance with material certification requirements common in commercial and industrial piping work. Licensed pipefitters and plumbing contractors are the primary installers of this type of fitting.

This weld tee is suited for use in commercial and industrial piping systems where carbon steel butt-weld fittings are specified. Typical applications include hydronic heating systems, process piping, steam and condensate lines, and mechanical room distribution headers. The standard-wall designation aligns with Schedule 40 pipe wall thickness for 3-inch nominal pipe size, making it compatible with common steel pipe used in trade installations across commercial mechanical systems.

Key Features

• 3-inch nominal pipe size straight tee configuration for in-line branch connections
• ASTM A234-WPB wrought carbon steel construction for pressure piping service
• Standard-wall (STD) designation matches Schedule 40 pipe wall thickness
• Butt-weld end connections for full-penetration weld joints
• Domestic manufacture supporting material traceability and certification requirements

Compatibility

Designed as an OEM-style butt-weld replacement or new-installation fitting for 3-inch nominal carbon steel pipe systems requiring standard-wall weld tee connections per ASTM A234-WPB material standards.

Installation Notes

Installation requires a qualified pipefitter or welder holding appropriate certifications for pressure piping work, as butt-weld fittings require full-penetration welding per applicable codes such as ASME B31.1 or ASME B31.9. Depressurize and isolate the piping system completely before cutting into any existing line. Pipe ends must be properly beveled and cleaned before fit-up to achieve a code-compliant weld joint. Post-weld inspection requirements vary by jurisdiction and system pressure class — confirm with the authority having jurisdiction before proceeding.
