Description
300# Galvanized Malleable Iron Reducing Tee
300# Galvanized Malleable Iron Reducing Tees are designed to create a three-way branch connection while transitioning to a smaller outlet size in higher-duty threaded piping systems.
Manufactured from durable malleable iron with a hot-dip galvanized finish, these Class 300 reducing tees provide dependable strength, corrosion resistance, and a compact way to distribute flow while changing pipe size in plumbing, waterworks, HVAC, mechanical, industrial, and outdoor applications.

Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in demanding threaded piping systems.
Reducing Branch Connection
The fitting provides three threaded openings and allows the piping system to branch while transitioning to a different nominal pipe size.
Hot-Dip Galvanized Finish
The galvanized coating conforms to ASTM A153 and provides added protection against rust and corrosion in moisture-prone and outdoor environments.
Why Use a Reducing Tee?
Branch and Reduce in One Fitting
A reducing tee combines a branch connection and pipe-size transition into a single fitting, helping simplify piping layouts and reduce the number of threaded joints.
Compact Flow Distribution
The three-way configuration allows flow to be divided or combined while accommodating different pipe sizes within the same threaded connection point.
Typical Applications
Mechanical & Commercial Piping
- Mechanical piping systems
- Commercial plumbing
- HVAC piping
- Water distribution
- General utility piping
- Branch-line size transitions
Galvanized & Outdoor Applications
- Outdoor piping
- Moist environments
- Waterworks installations
- Industrial piping
- General galvanized piping systems

Frequently Asked Questions
What is a 300# galvanized malleable iron reducing tee used for?
It is used to create a three-way threaded branch connection while transitioning between different nominal pipe sizes in a higher-duty piping system.
What type of connections does this fitting use?
The reducing tee uses female NPT threaded connections.
How is a reducing tee different from a standard tee?
A standard tee typically has equal-size connections. A reducing tee uses different nominal connection sizes so the piping system can branch while changing pipe size.
Is only the branch outlet reduced?
Reducing tee configurations can vary by size combination. Confirm the exact run and branch dimensions for the specific fitting being ordered rather than assuming which opening is reduced.
Can the tee divide or combine flow?
Yes. Depending on the piping arrangement, the fitting can divide flow into a branch or combine flow paths into a common run.
Why use a reducing tee instead of a standard tee and bushing?
A reducing tee can provide the required branch and size transition in one fitting, reducing the number of components and threaded joints in the installation.
Why choose galvanized instead of black malleable iron?
The hot-dip galvanized coating provides added protection against rust and corrosion in piping exposed to moisture, humidity, or outdoor conditions.
What standard applies to the galvanized coating?
Hot-dipped galvanized fittings conform to ASTM A153 according to the supplied product information.
What thread standard applies?
NPT threads conform to ASME B1.20.1.
Are Class 300 fittings UL Listed?
Yes. The supplied product information states that Class 300 fittings are UL Listed.
Important Ordering & Installation Notes
- Confirm all three nominal connection sizes before ordering.
- Do not assume the reduced connection is always the branch outlet; verify the exact size configuration shown for the selected fitting.
- All connections use female NPT threads.
- The branch connection is positioned at 90° to the main run.
- Confirm that Class 300 construction is appropriate for the intended piping system.
- NPT threads conform to ASME B1.20.1.
- Malleable fitting dimensions conform to ASME B16.3.
- Hot-dipped galvanized fittings conform to ASTM A153.
- Use compatible galvanized pipe, fittings, and thread sealant appropriate for the intended system.
- Avoid damaging the galvanized coating during handling and installation.
- Do not assume the “300#” class designation alone establishes allowable working pressure for every service condition.
- Verify pressure, temperature, media compatibility, potable-water requirements, applicable codes, and approval requirements before installation.
- Refer to the specification sheet and Certificate of Conformance for additional product information.
