Asc Engineered Solutions 300000403 Cast Iron 90 Elbow 3/8 in

Product Description

The ASC ENGINEERED SOLUTIONS 300000403 is a 3/8-inch black cast iron 90-degree elbow designed for threaded pipe systems in commercial and residential plumbing, HVAC, and gas distribution applications. Cast from iron and finished with a black coating, this fitting provides a durable, corrosion-resistant connection point where a 90-degree directional change is required in a pipe run. At 0.25 pounds, it is a compact, domestically produced fitting suited for low-pressure piping systems where cast iron is specified or preferred by code or design.

This elbow is commonly installed in black iron pipe systems used for natural gas, propane, steam, and compressed air distribution in light commercial and residential settings. The 90-degree angle makes it appropriate for tight turns between walls, floors, or mechanical rooms. It is a standard threaded fitting that connects to NPT-threaded pipe and other fittings of the same nominal size. Plumbers, pipefitters, and HVAC technicians routinely stock this type of fitting for service and new-installation work.

Key Features

• 90-degree elbow for directional pipe routing in threaded black iron systems
• 3/8-inch nominal fitting size for standard NPT-threaded pipe
• Cast iron construction for durability in gas, steam, and compressed air service
• Black coating finish for corrosion resistance and code-compliant identification in gas piping
• Domestically produced fitting
• Lightweight at 0.25 pounds for easy handling and stock

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8-inch NPT threaded black iron pipe systems.

Installation Notes

This fitting should be installed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC requirements for gas piping, or ASME B31 standards where applicable. Shut off and depressurize the pipe system completely before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape rated for the intended service medium before threading the fitting onto the pipe. Do not over-tighten; use a pipe wrench with appropriate jaw protection to avoid cracking the cast iron body.
