3 inch Black Malleable Iron Tee – VBGF 7830 for Threaded Pipe Systems

The BLK MAL TEE 3 inch VBGF 7830 is a heavy-duty threaded tee fitting manufactured from black malleable iron. Engineered for use in non-potable fluid, gas, or steam applications, this fitting provides a dependable 90° branch connection within threaded steel pipe systems. Its NPT threads are machined to ASME standards, allowing for consistent joint integrity across high-pressure systems.

Black malleable iron fittings such as the VBGF 7830 are frequently selected for industrial and commercial mechanical systems due to their strength, corrosion resistance in dry systems, and compatibility with steel piping. This tee supports full-flow configurations where alignment and mechanical reliability are essential.

Product Features for Contractors

• ✅ ASME-Compliant Threads Precision-cut NPT threads conform to ANSI B1.20.1 for pressure-rated connections.
• ✅ Cast Malleable Iron Manufactured to ASTM A197, providing excellent mechanical strength and impact resistance.
• ✅ Nominal Size: 3 inch diameter across all three ends (run and branch).
• ✅ Uncoated Black Finish Ideal for oil, gas, or steam systems where galvanized coatings are not required.
• ✅ Third-Party Certified Fitting meets industry codes for general-use pressure systems including those requiring UL/FM or CSA listings (varies by application).

Installation Guidance

This fitting is intended for use with carbon steel or black iron pipe in threaded systems. A pipe joint compound or PTFE tape is recommended on threads to ensure a leak-tight seal under pressure. Proper thread alignment and torque are necessary to avoid overstressing connections. Installations must adhere to local mechanical codes where applicable.

Applications

The 3 inch black malleable tee is commonly used in gas distribution piping, hydronic heating systems, compressed air lines, and low-pressure steam networks. It is also suitable for fire protection branch lines in dry systems, where high-temperature resilience and material strength are required.

Material Note

Black malleable iron fittings are intended for use in non-corrosive, non-potable applications. These fittings are not rated for use in potable water systems unless specifically certified with an internal coating. Their uncoated finish supports heat resistance and mechanical stability in elevated-temperature environments.

The BLK MAL TEE 3 inch VBGF 7830 provides a robust solution for forming 90° branches in pipe systems requiring threaded connections. Its heavy-wall construction, dimensional uniformity, and adherence to applicable performance standards make it a trusted choice in commercial and industrial piping assemblies.
