Asc Engineered Solutions 310520200 Malleable Iron Tee Xh

Product Description

The ASC Engineered Solutions 310520200 is a reducing malleable iron tee designed for threaded pipe systems in plumbing and mechanical applications. Built to Extra Heavy (XH) strength ratings, this black-finish fitting connects two 3/4-inch run ends to a 3/8-inch branch outlet, all via female pipe thread (FPT) connections. The malleable iron construction meets ASTM A-197 material specifications, and the thread profile conforms to ASME B1.20.1. Pressure performance is rated to ASME B16.3. This fitting carries UL and FM listings, making it appropriate for fire protection and other code-sensitive piping installations. Plumbers and pipefitters are the primary installers.

This tee is suited for residential and commercial piping systems where a reducing branch connection is required. The 3/4-inch run with a 3/8-inch branch outlet is common in gas distribution, water supply, and steam piping systems. The XH wall thickness provides additional pressure capacity compared to standard-weight fittings, making it appropriate for higher-demand service conditions. The black finish indicates a non-galvanized product, which is standard for gas piping applications.

Key Features

• Extra Heavy (XH) strength rating for higher-pressure service
• Malleable iron construction per ASTM A-197
• All three ends feature female pipe thread (FPT) connections per ASME B1.20.1
• Pressure rating per ASME B16.3
• UL and FM listed for code-sensitive installations including fire protection
• Black finish suitable for gas piping applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded malleable iron pipe systems requiring a 3/4 x 3/4 x 3/8 inch reducing tee configuration.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable local codes and IFGC or IPC requirements. Shut off all gas or water supply and depressurize the line before disassembling or threading connections. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not over-tighten threaded connections, as this can crack the fitting body.
