Product Features & Practical Advantages
Zero-Leakage Precision Threading
All threads are CNC-machined and verified by Go/No-Go thread gauges to ensure 100% compatibility with internal threaded pipes, manifolds, and pump ports.
Compact & High-Leverage Square Head
The dimension of plug square is tightly controlled to fit standard socket and adjustable wrenches perfectly, allowing max torque application and quick installation in tight spaces.
Robust Solid Design
Leadtek's solid square head plug acts as a definitive flow terminator, capable of withstanding constant hydraulic impulses without deformation.
Extreme Environment Resistance
Exceptional resistance to pitting, crevice corrosion, and acidic media-ideal for marine, pharmaceutical, and water treatment engineering.

Leadtek Quality Assurance: Factory-Direct Advantage
100% Quality Inspection Flow
Every single batch of stainless steel pipe plugs undergoes Leadtek's proprietary Quality Control protocol before shipment:
Spectrometer Material Verification
Ensures the exact Nickel and Chromium content meets ASTM/ISO standards.
Dimensional & Thread Testing
Strict verification using specialized mechanical gauges.
Sealing Integrity Test
Random air-under-water testing to guarantee no macro-porosity exists in the investment casting.
FAQ
Q: Can I get MTC (Material Test Certificate) for my order?
A: Yes, absolutely. We provide standard EN 10204 3.1 Material Test Certificates with every shipment, verifying the chemical composition and mechanical test properties.
Q: What is the lead time for a bulk wholesale order of square head plugs?
A: For standard ISO 4144 sizes (1/8" to 4"), we maintain regular raw casting stock. Orders can usually be machined, inspected, and shipped within 15–30 days depending on volume.
Q: Do you support custom thread standards like Metric or special NPT lengths?
A: Yes. As a direct manufacturer, our CNC workshop provides flexible OEM & custom drawing support. You provide the blueprints, and we deliver precision matching.
Q: Do you offer cross-product purchasing for complete pipeline assemblies?
A: Yes, Leadtek is a full-range provider. You can source Stainless Steel Ball Valves (1PC, 2PC, 3PC, Flanged), Gate Valves, and complete ISO 4144 pipe fittings simultaneously to reduce your shipping and communication costs.
