Water Service Connection Kits for Water Industry Applications
Table of Contents
Introduction
Water Service Connection Kits (Water Branching Kits) are complete assemblies used to connect individual consumers, buildings, agricultural units, or distribution nodes to the main water supply network. These kits ensure a reliable, leak-free, pressure-rated connection between the main pipeline (usually PE100 / ductile iron) and the service line.
They are designed for municipal water distribution, rural water networks, irrigation systems, metering connections, and domestic supply lines.
This page provides a technical overview of water connection kits, their components, standards, installation requirements, and engineering recommendations.
What Is a Water Service Connection Kit?
A water connection kit is a packaged set of components that enables safe and standardized connection to:
- PE main pipelines
- Ductile iron pipelines
- Steel pipelines
These kits typically include:
Standard Components
- Service Saddle (Branch Saddle / Tapping Saddle)
- Corporation Stop (Brass / High-grade polymer)
- HDPE Service Pipe (Usually PE80 or PE100, SDR11)
- Compression or Electrofusion Fittings
- Isolation Valve (Optional)
- Meter Box & Meter Accessories (Optional)
- Flanged / Threaded Transition Pieces
Key Features
- Leak-free connection
- High pressure rating (PN16 or PN25)
- Corrosion protection
- Compatibility with HDPE, DI, Steel
- Quick and safe installation
- Suitable for potable water
Types of Connection Kits (Water Industry)
Comparison: PE80 vs PE100 in Agricultural Engineering
| Criteria | PE80 | PE100 |
|---|---|---|
| Pressure capability | Medium | High |
| Flexibility | Higher | Medium |
| Cost | Lower | Higher |
| Wall thickness | Higher | Lower |
| Recommended use | General irrigation | High-pressure / long-distance farm pipelines |
Molecular Structure
Both PE80 and PE100 are classified as HDPE with:
| Property | PE80 | PE100 |
|---|---|---|
| Density | 0.94–0.95 g/cm³ | 0.95–0.97 g/cm³ |
| Crystallinity | Medium | High |
| Flexibility | Very High | Medium |
| ESCR (Crack Resistance) | High | Very High |
| MFR | 0.2–1.4 g/10 min | 0.2–1.0 g/10 min |
| UV Protection | 2–2.5% Carbon Black | 2–2.5% Carbon Black |
Agriculture Stress Factors Affecting Molecular Behavior:
UV exposure
Temperature cycling (night/day pressure changes)
Soil movement & tractor load
Fertilizer-induced chemical exposure
PE100 performs significantly better in pressure cycling and long-distance pipelines.
Applications in the Water Industry

Technical Specifications & Pressure Classes
Pressure Ratings
- PN10 – Low-pressure rural systems
- PN16 – Standard potable water distribution
- PN25 – High-pressure transmission / pumping branches
Material Options
- PE100 / PE80
- Ductile iron GJS400
- Cast steel WCB
- Stainless steel
- Brass (CW617N or CW602N dezincification-resistant)
Coatings
- Internal epoxy (200–300 μm)
- External FBE
- Zinc + epoxy for DI components
Advantages in Water Distribution
- Leak-free, regulated branching
- Long-term reliability (50-year design life)
- Compatible with multiple pipe materials
- Fast installation
- Hygienically safe for potable water
Standardized components reduce installation errors
Installation Guidelines
- Use EF tapping saddle (ISO 13950)
- Clean and scrape pipe surface
- Use clamps during fusion
- Respect heating and cooling cycles
- Pressure test before backfilling
Installing on DI or Steel Mainline
- Use stainless-steel tapping clamp
- Ensure correct gasket placement
- Tighten bolts uniformly
- Drill through clamp port
- Install corporation stop
Service Line Installation
- Use PE80/PE100 SDR11 for domestic supply
- Compression fittings must meet ISO 17885
- Install meter box on a stable platform
Avoid excessive bending of service line
FAQs
When connecting to PE100 main pipes, especially in high-pressure areas or when absolute sealing is required.
PE100 SDR11 or PE80 SDR11 for potable water supply lines.
Yes—if made from dezincification-resistant brass (CW602N) or certified polymers.
Yes, using stainless-steel tapping clamps and flanged adaptors.
50+ years if properly installed and pressure-rated components are used.
