Description
NPT Square Face Galvanized Square Edge Straight Tee Pipe Fittings
When you need reliable, corrosion-resistant pipe fittings for your industrial applications, NPT Square Face Galvanized Square Edge Straight Tee Pipe Fittings deliver exceptional performance. These T-shaped flexible press components are particularly built for part or combining liquid stream in requesting mechanical channeling frameworks. You'll appreciate the three equal-sized openings with National Pipe Taper (NPT) strings that guarantee tight, leak-proof seals for pressurized frameworks. The square confront plan gives predominant torque hold and torque application, making establishment less demanding in tight spaces. With hot-dip galvanized coating, these fittings unravel basic erosion challenges in high-humidity environments.



Technical Specifications
Our fittings are made to meet the most requesting mechanical benchmarks. Built from ASTM A197 moldable press, these fittings offer prevalent ductility compared to fragile cast press choices. The accuracy NPT threading takes after ANSI/ASME B1.20.1 measures with a 60-degree string point and 1:16 decrease proportion. You can believe these fittings for dependable execution beneath pressure.

Materials and Surface Treatment
We utilize ASTM A197 vault moldable press for extraordinary ductility and quality. Our hot-dip galvanizing prepare applies a least 86-micron zinc coating, surpassing industry guidelines. This treatment gives anodic security that anticipates rust arrangement indeed when the coating is scratched or damaged.
Standards and Certifications
- ASTM A197 (Malleable Iron)
- ASME B16.3 (Dimensional Standards)
- ANSI/ASME B1.20.1 (Threading)
- ASTM A153 (Galvanizing)
- ISO 9001 Quality Management System






Application Areas
Industrial Compressed Discuss Frameworks: Culminate for open air pneumatic applications where dampness condensation happens regularly. The galvanized security anticipates inner rust whereas NPT Square Face Galvanized Square Edge Straight Tee Pipe Fittings edges enable proper torque application for leak-free seals.
Agricultural Water system Systems: Perfect for heavy-duty water system manifolds uncovered to soil causticity and climate varieties. These fittings convey water consistently and stand up to affect harm from cultivating equipment.
HVAC Steam Frameworks: Basic for plant steam warming lines, steam traps, and return line branching. The square confront plan exceeds expectations in dazzle establishments where positive torque engagement anticipates perilous steam leaks.
Installation Instructions
- Ensure pipe closes are clean and free from burrs
- Apply suitable string sealant or tape to male threads
- Hand-tighten the fitting until snug
- Use torques on square faces for last tightening
- Tighten 2-3 extra turns past hand-tight
- Avoid over-tightening to avoid string damage
Packaging and Shipping
We bundle fittings in defensive cartons with person wrapping to avoid scratching amid transport. Standard shipping incorporates dampness boundaries to secure the galvanized wrap up. Express conveyance choices are accessible for critical orders.





Quality Control
Our quality control handle guarantees each fitting meets your details. We perform string gaging with calibrated L1 Go/No-Go ring gages, confirm 90-degree pivot arrangement utilizing optical comparators, and conduct attractive acceptance testing for coating thickness. Arbitrary hydrostatic testing at 80-100 psi affirms leak-proof performance.
