Typical lifespan is 50+ years
PP Compression Fittings have a typical lifespan of 50 years or more. This matches the lifespan of PP pipe. The fittings are designed for long-term service. Example: systems installed in the 1990s are still operating.
Lifespan in cold water
In cold water systems, lifespan exceeds 50 years. Material degradation is minimal. PP Compression Fittings can last 70+ years in cold conditions.
Lifespan in hot water
Hot water reduces lifespan slightly. At 60°C, lifespan is still 50+ years. At 82°C, lifespan is 30-40 years. PP Compression Fittings hot water life depends on temperature.
Effect of temperature on lifespan
Higher temperatures accelerate material aging. Each 10°C increase reduces lifespan. At 20°C, lifespan is over 100 years. PP Compression Fittings follow the aging rule.
Effect of pressure on lifespan
Pressure also reduces lifespan over time. Higher pressure accelerates creep. The pressure rating helps determine safe pressure. PP Compression Fittings are designed for 50-year life at rated pressure.
Effect of water quality
Aggressive water can affect the material. PP is resistant to most water chemistry. Fittings maintain integrity in normal water. PP Compression Fittings are compatible with most water qualities.
Effect of UV exposure
UV exposure is a threat to PP fittings. Sunlight degrades the material. This can reduce lifespan to just a few years. PP Compression Fittings must be protected from UV.
Effect of mechanical damage
Impact damage reduces lifespan significantly. Scratches or cuts weaken the material. PP Compression Fittings require careful handling.

Example: residential hot water system
A home uses PP Compression Fittings for hot water at 60°C. The system operates at 4 bar. The fittings are expected to last 50+ years. Example: a lifetime investment for the homeowner.
Example: commercial building plumbing
A commercial building uses PP Compression Fittings for all plumbing. The system operates at moderate temperatures. The fittings last for decades. Example: a durable, long-term plumbing system.
Example: cold water supply
A cold water supply system runs at 20°C. PP Compression Fittings should last 70+ years. Example: a long-term reliable system.
Final lifespan summary
PP Compression Fittings have a typical lifespan of 50+ years. Cold water systems can last 70+ years. Hot water at 60°C lasts 50+ years. UV exposure is the biggest threat. Pressure and water quality also affect lifespan. With proper installation and protection, PP Compression Fittings provide decades of reliable service. Example: a wise investment for any building.
