Asc Engineered Solutions 320201122 Taper Tap Coupling 4 in

Product Description

The ASC Engineered Solutions 320201122 is a 4-inch Extra Heavy black steel taper tap coupling designed for use in threaded pipe systems where additional wall thickness and mechanical strength are required. This fitting accepts a tapered tap to create a new threaded branch outlet in an existing pipe without cutting the line. It is built from extra heavy black steel, providing greater durability and pressure resistance compared to standard-weight fittings. Plumbers, pipefitters, and mechanical contractors typically install this type of coupling in commercial and industrial piping applications.

This coupling is suited for black steel pipe systems in commercial plumbing, fire suppression, steam, gas distribution, and industrial process piping where extra heavy fittings are specified. The extra heavy wall designation makes it a common choice when system pressure ratings, code requirements, or engineering specifications call for heavier-duty components than standard or Schedule 40 fittings provide. It is intended for use by licensed plumbers and pipefitters working on threaded iron or steel pipe installations.

Key Features

• 4-inch fitting size accommodates large-diameter threaded pipe systems
• Extra heavy wall construction provides increased strength and pressure capacity
• Taper tap design allows threading of a branch outlet into the coupling body
• Black steel material is compatible with gas, steam, and non-potable water piping
• Weighs 7.88 pounds, consistent with extra heavy steel construction

Compatibility

Designed as an OEM-style replacement and standard fitting for 4-inch extra heavy threaded black steel pipe systems in commercial and industrial piping installations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or ASME B31 piping standards. Shut off and depressurize the pipe system completely before installing or modifying any fittings. Use appropriate pipe thread sealant or PTFE tape on all threaded connections. Do not overtighten threaded joints; follow standard trade practice for thread engagement on NPT connections.
