The HDPE stub end price list are all molded type fittings. We have included sizes from DN40 (1-1/4″) up to size DN630 (24″). All the prices listed are in Philippine Peso (Php) with value added tax (VAT) included. The price is per one piece of stub end.

HDPE stub ends are specialized fittings designed to work with flange adapters in piping systems. These components allow for easy disassembly and reconnection—especially in large-diameter pipelines or systems that require periodic maintenance. Therefore, reviewing the latest HDPE stub end prices in the Philippines is essential for engineers, contractors, and procurement officers managing water, chemical, or industrial projects.

What Is an HDPE Stub End?

An HDPE stub end is a short pipe section with a flared end, used in conjunction with a loose backing flange to form a flanged joint. This design enables pipelines to be mechanically connected, rather than fused, allowing for quick disassembly when necessary.

Moreover, stub ends provide excellent flexibility, particularly in systems that require modular components, routine inspections, or equipment access. Their use is common in installations where welded joints may not be ideal.

Common Applications of HDPE Stub Ends

Stub ends serve various functions across multiple industries. Common applications include:

🔧 Water and wastewater treatment systems – for valve, pump, and tank connections
🧪 Chemical and process industries – where frequent equipment changes occur
🛠️ HDPE flange connections – allowing for maintenance access
🚧 Temporary or modular piping systems – used in projects or pilot plants
🏗️ Municipal utility lines – where components may need future replacement

In addition, stub ends help reduce stress on fusion joints and make alignment easier during installation.

Sizes, SDR Ratings, and Joint Types

HDPE stub ends come in various configurations to match the system’s pressure rating and pipe size:

Available Sizes:
- Commonly range from 20mm up to 1200mm
SDR Compatibility:
- Designed to match SDR11, SDR17, SDR21, and other ratings
Jointing Method:
- Used with backing flanges, typically made of carbon steel or stainless steel
Manufacturing Type:
- Injection-molded for small diameters
- Fabricated for larger diameters

Furthermore, stub ends are often paired with stub flanges and gasket materials for a complete flanged joint system.

Factors That Affect HDPE Stub End Pricing

Several factors contribute to the overall cost of HDPE stub ends:

Size and SDR rating
Material grade and thickness
Fabrication method (molded vs. fabricated)
Type of flange used in the connection
Supplier location, brand, and lead time
Project volume and custom requirements

As a result, larger or custom-fabricated stub ends generally cost more due to higher material and labor input.

Installation and Handling Tips

To ensure proper fit and long-lasting performance, follow these best practices:

Match the stub end’s SDR rating with the connecting HDPE pipe
Always clean the contact surfaces before assembly
Align the stub end and flange precisely to avoid leaks
Use compatible gaskets and bolts for flanged joints
Apply even torque across flange bolts to maintain a uniform seal

Moreover, check flange face alignment using a straight edge before final tightening.

Conclusion

In summary, HDPE stub ends are crucial fittings that allow flexible, modular, and easy-to-maintain piping connections. Their role in flanged joints makes them a go-to option in systems that demand both strength and accessibility.

Therefore, consulting an up-to-date HDPE stub end price list ensures better budget control, faster procurement, and more reliable installations.
