3/8 inch BLK MAL Tee VBGF 7822 – Threaded Tee for Branch Line Integration

The 3/8 inch BLK MAL Tee VBGF 7822 is a threaded malleable iron fitting designed to provide a secure junction point for connecting three sections of pipe at 90° angles. Manufactured to meet dimensional and pressure requirements for general-purpose piping, it is suitable for use in air, water, gas, and low-pressure steam systems.

Made from malleable cast iron and coated with a protective black oxide finish, this tee is engineered for strength and resistance to mechanical stress. Threaded ends conform to NPT standards, ensuring a tight, reliable seal when installed with appropriate thread sealant or PTFE tape.

Key Performance Features

• ✅ Malleable Iron Construction – Offers high tensile strength and ductility, supporting installation in systems subject to vibration and moderate pressure changes.
• ✅ Threaded NPT Ends – Standardized threading for compatibility with 3/8 inch schedule 40 or schedule 80 steel pipe and fittings.
• ✅ Dimensional Accuracy – Manufactured to ANSI/ASME B16.3 specifications for proper fit and alignment across assemblies.
• ✅ Black Finish – Suitable for non-corrosive applications and indoor system installations; protects against handling abrasion.
• ✅ Versatile Branching Functionality – Allows for equal-size pipe branching in pressurized or mechanical system layouts.

Installation Notes

Install using pipe wrenches and apply thread sealant rated for system fluid and temperature conditions. Hand-tighten followed by appropriate torque with tooling to ensure proper engagement without overstressing threads. Confirm alignment of run and branch lines prior to full tightening to minimize stress at adjoining joints.

Specifications

• Material: Black malleable iron
• Connection Type: NPT Threaded (F x F x F)
• Nominal Size: 3/8 inch
• Standard Compliance: ANSI/ASME B16.3, UL and FM listings as applicable for gas or fire protection systems

Typical Use Cases

Used in plumbing, HVAC, and industrial process systems requiring directional branch lines. Commonly applied in compressed air systems, natural gas piping (when black iron is approved), and mechanical loops for equipment tie-ins or distribution manifolds.

Material Overview

Malleable iron fittings combine machinability and pressure resistance, making them suitable for installations where rigid support, thermal fluctuation tolerance, and mechanical vibration resistance are necessary.

The 3/8 inch BLK MAL Tee VBGF 7822 provides a durable, code-compliant solution for contractors requiring reliable branch integration in threaded piping systems. It is a standard component in heavy-duty plumbing and mechanical layouts demanding performance and longevity.
