Tee Thread Fitting

Overview

A malleable iron equal tee (also called a threaded equal tee) is a T-shaped fitting used to create a 90° branch in a piping system where all three outlets are the same size. It is widely used in fire protection sprinkler piping, HVAC, compressed air, and general industrial pipelines. With reliable strength and good machinability, malleable iron equal tees provide stable performance for threaded pipe networks and help simplify installation and maintenance.

Product Description

This equal tee features three equal-diameter female threaded outlets, allowing one pipeline to split into two directions, or two lines to merge into one. It is manufactured from malleable cast iron and precisely threaded for secure engagement with steel pipes. The fitting is available with BSPT or NPT threads to match regional standards and jobsite requirements. Common surface finishes include hot-dip galvanized and black (as required).

Key Features & Benefits

• Equal Outlets for Clean Branching
  All three ends have the same size, making it ideal for symmetrical branch piping layouts.

• Durable Malleable Iron Body
  Good tensile strength and impact resistance for dependable service in demanding installations.

• Accurate Threading Options
  Available in BSPT and NPT to ensure compatibility with local pipe standards.

• Corrosion Protection Options
  Typical finishes include hot-dip galvanized for enhanced corrosion resistance or black for indoor/controlled environments.

• Fast Installation & Easy Maintenance
  Threaded connection reduces installation time and allows convenient disassembly for modifications or repairs.

• Common Choice for Fire Protection Systems
  Frequently used in sprinkler branch lines and riser connections where threaded piping is specified.

FAQ

1) What is the difference between an equal tee and a reducing tee?

An equal tee has three outlets of the same size. A reducing tee has a smaller branch outlet (one outlet is reduced).

2) Can I mix BSPT and NPT in the same piping system?

It’s not recommended. BSPT and NPT have different thread angles and profiles, and mixing them can lead to leakage or thread damage. Choose one standard for the entire system.

3) Is this equal tee suitable for fire sprinkler systems?

Yes. Threaded malleable iron equal tees are widely used in fire protection piping, especially where threaded steel pipe is specified. Confirm required approvals/certifications based on your project.

4) What finish should I choose: galvanized or black?

• Galvanized: better corrosion resistance, suitable for humid or corrosive environments.

• Black: often used indoors or where coating/painting is applied after installation.

5) What information do you need for an accurate quotation?

Please provide: size list, thread standard (BSPT or NPT), finish (galvanized/black), quantity, and any required standard/certifications.
