1. Corrosion Resistant: resist chemical matters or electron chemical corrosion

2. Higher Flow Capacity: smooth interior walls result in lower pressure loss and higher volume than metal fittings

3. Lower Installation Costs: light weight and ease of installation

can reduce installation costs by as much as 50% over metal fittings
4. Longevity: more than 50 years under proper use

5. Non-conductive: Good insulation, assuring a safe system
6. Fire resistance: Self-extinguishing, do not support combustion
7. Impact strength: Resistant to compression and impact, suitable

to be buried in concrete
