Standard NPT & BSPT triple female threads on three ports are machined with high precision, enabling tight leak-free three-way branch connection without extra sealant in most scenarios.
3.Easy & Quick Installation
Triple female thread design realizes direct three-way pipeline diversion joint, no extra adapters required; compatible with common pipe wrenches for fast on-site assembly of branch pipelines.
4.Stable Structural Strength
Made of thickened high-quality malleable iron, the tee boasts outstanding mechanical toughness and impact resistance, rated for Class 300 heavy working pressure and compliant with ANSI B16.3 standard.
5.Wide Compatibility & Cost-Efficient
Suitable for indoor & outdoor plumbing, fire protection, natural gas, water irrigation, petroleum and light industrial three-way branch pipelines; provides reliable high-pressure performance at a competitive cost vs premium alloy alternatives.
Dimensions and Specifications
Our Class 300 hot dipped galvanized equal tees support a full range of standard inch sizes, mainstream options include:
- 1/8", 1/4", 3/8", 1/2", 3/4", 1"
- 1-1/4", 1-1/2", 2", 2-1/2", 3", 4"
- Custom size, logo and packaging requests are acceptable
Every tee is manufactured with precise dimensional tolerance. Solid thickened one-piece casting structure greatly prevents deformation or loosening under normal Class 300 heavy working pressure.
Materials and Surface Treatments
1.Main Body Raw Material
High-quality thickened malleable iron (ANSI B16.3 compliant) features high toughness, strong impact resistance and stable mechanical performance under Class 300 heavy pressure rating.
2.Surface Finish
Full internal & external hot dipped galvanized zinc finish forms a uniform anti-corrosion protective film covering the whole tee, effectively resisting rust, moisture and mild chemical erosion for long-term indoor concealed and outdoor exposed pipeline use.
3.Thread Processing
Precision CNC machined NPT & BSPT triple female threads on three ports ensure tight, leakproof three-way branch connection fit when connecting standard threaded pipes.
Standards and Certifications
Our products comply with rigorous international industry standards:
- Compliant with ANSI B16.3 (Class 300 Heavy Malleable Iron Threaded Pipe Fittings)
- ISO9001 quality management system certified
All Class 300 hot dipped galvanized equal tees are fully tested for pressure resistance, thread precision and three-way branch pipeline sealing performance prior to packaging.

Installation Instructions
- Thread Preparation: Clean male pipe threads and triple female threads of tee, apply PTFE tape evenly if needed.
- Hand Screw Alignment: Rotate the equal tee by hand to align threads without forced twisting.
- Tool Tightening: Use two pipe wrenches to secure each port evenly, avoid over-tightening to prevent thread damage.
- Leak Test: Complete pressure test after installation to confirm zero leakage at all three connection joints.
- Post-Check: Inspect three-way branch pipeline connection regularly for long-term stable sealing.
Follow local plumbing, gas and fire safety codes during all installation work.
Packaging and Shipping
Each hot dipped galvanized malleable iron equal tee is wrapped with anti-collision protective packaging to avoid scratches and abrasion during shipment. Moisture-resistant packaging materials are used to fully protect the complete zinc anti-corrosion galvanized coating intact. Large bulk shipments are loaded on standard pallets for convenient handling and container loading.

Quality Control
1.Raw Material Inspection
Every batch of thickened malleable iron raw material is inspected for chemical composition and mechanical toughness to meet Class 300 heavy standard.
2.Pressure Burst Test
Random samples of equal tees are subjected to hydrostatic pressure testing matching Class 300 high working pressure rating.
3.NPT & BSPT Thread Precision Check
CNC thread gauges inspect triple-end thread accuracy to guarantee tight three-way branch pipeline leak-free connection.
4.Surface Anti-Rust Inspection
Full hot dipped galvanized zinc coating surface is fully checked to avoid galvanization defects, bare iron spots and surface flaws.

FAQ
Q: Can this hot dipped galvanized malleable iron equal tee be buried underground?
A: It can be buried underground with extra anti-corrosion wrapping protection; direct burial without additional coating is not recommended for long-term service life.
Q: What is the correct installation method for this Class 300 hot dipped galvanized equal tee?
A: Wrap PTFE tape evenly on all three NPT & BSPT female ports, tighten each port symmetrically with two pipe wrenches; do not over-torque to avoid thread damage.
Q: Can it cope with pipeline thermal expansion?
A: As rigid triple-port threaded fitting, we suggest installing expansion joints for long three-way branch pipelines with obvious temperature variation.
Q: Can it connect different material pipes like PVC and steel?
A: It can connect standard NPT & BSPT threaded pipes of different materials, ensure thread specification matches before assembly on all three ports.
Q: Why choose hot dipped galvanized malleable iron tee instead of stainless steel?
A:It features thickened casting, high mechanical toughness, stable 300PSI high pressure resistance, full internal & external zinc anti-corrosion coating, and offers great cost performance for indoor & outdoor plumbing, gas, water irrigation, petroleum and light industrial three-way branch pipeline projects.
