Equal Tee Pipe Fitting

-- Steady & Reliable Manufacturer --

Introduction

An equal tee pipe fitting — also called a straight tee or plain tee — is a T-shaped connector with three ports of identical size. It allows a single pipeline to split into two branches of equal diameter, or two lines to merge into one, at a 90° angle. The equal tee is the most frequently specified tee type across plumbing, HVAC, process piping, and compressed air systems, making it a cornerstone fitting in any piping catalogue.

Fenglan equal tee fittings are produced in brass, stainless steel (304/316), and carbon steel, covering threaded, compression, push-fit, and socket-weld connection methods. All products are dimensionally verified against the applicable standard (EN 10226, ASME B16.11, or DIN 2999) and pressure-tested before dispatch to confirm zero-leakage performance.

Applications

  • Domestic Plumbing: Water supply branch connections under sinks, behind toilets, and in bathroom riser manifolds where equal-bore splitting is required.
  • Central Heating Systems: Radiator circuit branches, boiler return headers, and underfloor heating zone manifolds.
  • Compressed Air Distribution: Workshop ring-main branch drops, air tool supply taps, and compressor outlet manifolds.
  • Industrial Process Piping: Chemical dosing headers, cooling water distribution, and instrumentation tapping points in plant piping systems.
  • Fire Suppression Systems: Sprinkler branch lines and deluge system headers where equal-flow splitting is essential for system balance.

Advantages

  • Equal Flow Distribution: Identical port size ensures balanced flow splitting without the pressure drop penalty of reducing tees when branch flow equals main flow.
  • Multiple Connection Options: Threaded, compression, push-fit, and weld-end variants allow the same equal tee configuration to suit different pipe materials and installation methods.
  • Multi-Material Range: Available in brass, 304, 316, and carbon steel from a single supplier, simplifying procurement for mixed-material piping systems.
  • Precision Machining: CNC-turned threads and flat-faced sealing surfaces ensure square, square-thread engagement that prevents cross-threading and provides leak-free assembly first time.
  • Standards Compliance: Products conforming to ASME B16.11, EN 10226, and DIN 2999 are accepted by inspection bodies and specification engineers worldwide without the need for deviation approvals.
  • Scalable Supply: Stocked in standard sizes for rapid dispatch; custom sizes and special alloys produced to order for larger OEM and project requirements.

Frequently Asked Questions

  • Q: What is the difference between an equal tee and a reducing tee?
  • A: An equal tee has all three ports at the same diameter, making it ideal when the branch flow equals the main line flow. A reducing tee has a smaller branch port, used when only a portion of the main flow is diverted — for example, a 1" main with a 1/2" branch for a sub-circuit.
  • Q: Can I use a brass equal tee in a gas pipeline?
  • A: Yes, subject to local gas authority approval. Brass tees are commonly used in natural gas and LPG supply lines at domestic pressures. Confirm the pressure rating and thread standard comply with your regional installation code before use.
  • Q: Which tee material is best for hot water systems above 90°C?
  • A: For sustained temperatures above 90°C, stainless steel 304 or carbon steel is preferred. Brass tees are typically rated to 110°C for short peak temperatures, but continuous exposure above that requires stainless or carbon steel to maintain long-term seal integrity.
  • Q: Do you offer socket-weld equal tees for high-pressure service?
  • A: Yes. Socket-weld and butt-weld equal tees are available in 304, 316L, and carbon steel to ASME B16.11, suitable for high-pressure pipework where threaded joints are not permissible.
  • Q: What is your standard packing for export shipments?
  • A: Small fittings are packed in polybags, then placed in inner cartons and master cartons with foam padding. Each carton is labeled with part number, quantity, material grade, and batch code. Pallet and container packing are arranged according to buyer requirements.
