Asc 310521802 Malleable Iron Tee 1x1x0.25 Inch Xh Black

Product Description

The ASC Engineered Solutions 310521802 is a black malleable iron tee fitting rated to Extra Heavy (XH) strength, designed for use in threaded pipe systems requiring reliable branch connections. Manufactured to ASTM A-197 material specifications and pressure-rated per ASME B16.3, this fitting features female pipe thread (FPT) connections on all three ends. Thread form conforms to ASME B1.20.1, ensuring consistent engagement with standard tapered pipe threads. It carries UL and FM listings, making it suitable for applications where listed fittings are required. Licensed plumbers and pipefitters install this type of fitting in commercial and industrial piping systems. The fitting weighs 1.09 pounds.

This tee is appropriate for use in black iron pipe assemblies common to gas distribution, fire protection, and industrial fluid piping systems. The XH strength rating suits higher-pressure or more demanding service conditions compared to standard-weight fittings. The black finish is typical for gas and steam piping applications. All three ports are FPT, so the installer threads male-threaded pipe or nipples directly into each end without adapters. The 0.25-inch branch port accommodates a quarter-inch branch line off a 1-inch run.

• UL and FM listed for use in listed-fitting-required applications
• Black finish suited for gas and steam piping installations
• Reducing branch: 1-inch run x 1-inch run x 0.25-inch branch

Compatibility

Designed as an OEM-style threaded branch fitting for black iron pipe systems using 1-inch run pipe and a 0.25-inch branch, conforming to standard NPT thread systems per ASME B1.20.1.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the IFGC or IPC as required by the system type. Shut off and depressurize the piping system completely before disassembly or fitting installation. Apply an appropriate thread sealant or PTFE tape to male threads before assembly, following the sealant manufacturer instructions for the service medium. Do not over-tighten threaded connections, as malleable iron fittings can crack if subjected to excessive torque.
