3/4 inch x 1/2 inch x 1/2 inch Black Iron Reducing Tee Female x Female x Female

3/4" x 1/2" x 1/2" Black Malleable Iron Reducing Tee – Threaded Fitting for Gas and Mechanical Systems

The BLK MAL TEE 3/4X1/2X1/2 is a black malleable iron reducing tee with female NPT connections, designed to facilitate directional flow while reducing pipe size in gas, water, and general-purpose piping networks. Its compact form factor and dimensional accuracy make it suitable for confined installations and transition points in branch systems.

Manufactured from ASTM-grade malleable iron with a black finish, this fitting supports low- to medium-pressure mechanical systems and is intended for use in non-potable applications where corrosion protection is not externally required.

Key Performance Attributes

• ✅ Black Malleable Iron Construction – Provides excellent tensile strength and resistance to mechanical impact in utility-grade installations.
• ✅ Threaded Female Ends – Conforms to ANSI/ASME B1.20.1 NPT standards for reliable engagement and sealing with compatible steel or iron pipe.
• ✅ Reducing Tee Configuration – Accommodates transitions from 3/4" main lines to 1/2" branch lines without separate bushings or adapters.
• ✅ System Compatibility – Suitable for natural gas, compressed air, and low-pressure hydronic systems in commercial and residential builds.

Installation Guidance

Use thread sealant or PTFE tape rated for the specific system medium. Proper alignment and torque application are essential to avoid thread distortion. This fitting is not intended for welding or use in corrosive fluid transport without additional coating or treatment.

Technical Specifications

• Material: Black Malleable Iron
• Connection Type: Female NPT x Female NPT x Female NPT
• Nominal Sizes: Inlet: 3/4" | Branch: 1/2" | Run Outlet: 1/2"
• Standard Compliance: ANSI/ASME B16.3 and B1.20.1

Application Scenarios

This reducing tee is commonly used in gas distribution lines, mechanical equipment loops, compressed air systems, and manifold branches. It supports structural integrity in threaded piping installations while enabling flow redirection and diameter transition in a single fitting.

Material Insight

Black malleable iron has long been specified for fuel gas and mechanical system applications due to its machinability, impact resistance, and pressure handling capability. The black finish is suitable for dry or indoor environments not requiring corrosion-resistant coatings.

The BLK MAL TEE 3/4X1/2X1/2 provides durable and code-compliant performance in a variety of threaded iron piping configurations. Specify this fitting for transition tees in layout-constrained environments where space, alignment, and branch size variation are key factors.
