Construction & Applications
Malleable Iron Construction
Manufactured from malleable iron castings conforming to ASTM A197 for dependable strength and durability in threaded piping installations.
Bull Head Configuration
Unlike a standard reducing tee, a bull head tee has a branch connection that is larger than the two opposing run connections.
Hot-Dip Galvanized Finish
The galvanized coating conforms to ASTM A153 and provides additional protection against rust and corrosion in moisture-prone and outdoor installations.
What Is a Bull Head Tee?
Larger Branch Connection
A bull head tee is a reducing tee configuration where the branch outlet is larger than the two opposing run connections. This is the reverse of a more common reducing tee with a smaller branch.
Specialized Distribution Layouts
The configuration is useful where a larger line must connect to two smaller opposing runs or where the piping design requires this specific connection-size relationship.
Typical Applications
Commercial & Mechanical Piping
- Commercial plumbing systems
- Mechanical piping
- Water distribution systems
- General utility piping
- Branch piping layouts
- Specialized distribution systems
Galvanized Applications
- Outdoor piping
- Moist environments
- Water-service applications
- Industrial installations
- General galvanized piping systems

Frequently Asked Questions
What is a bull head tee?
A bull head tee is a reducing tee where the branch connection is larger than the two opposing run connections.
How is a bull head tee different from a standard reducing tee?
A standard reducing tee commonly has a smaller branch than the main run. A bull head tee reverses that arrangement, with the branch larger than the opposing run connections.
Does a bull head tee automatically provide equal flow to both run outlets?
No. The fitting provides the physical connection arrangement, but actual flow distribution depends on system pressure, downstream resistance, pipe sizing, valve position, and the overall piping design.
What type of connections does this fitting use?
The fitting uses female NPT threaded connections.
Does the branch connect at 90 degrees?
Yes. The branch connection is positioned at 90 degrees to the two opposing run connections.
Are all three openings the same size?
No. A bull head tee uses different connection sizes, with the branch larger than the opposing run openings. Verify the exact size combination before ordering.
Why choose a galvanized bull head tee?
The hot-dip galvanized finish provides additional resistance to rust and corrosion for piping exposed to moisture 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.
Is this fitting UL Listed and FM Approved?
The supplied product information states that Class 150 fittings are UL Listed and FM Approved at 300 PSI.
Important Ordering & Installation Notes
- Confirm all three nominal connection sizes before ordering.
- A bull head tee has a larger branch connection than its two opposing run connections.
- Do not assume the connection-size orientation is the same as a standard reducing tee.
- All connections use female NPT threads.
- Actual flow will not necessarily divide equally between opposing outlets; system hydraulics determine flow distribution.
- 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, thread sealant, and accepted threaded installation practices.
- Avoid damaging the galvanized coating during handling and installation.
- Verify system pressure, temperature, media compatibility, potable-water requirements, applicable codes, and approvals before installation.
- Refer to the specification sheet and Certificate of Conformance for additional product information.
