Typical lifespan is 50+ years
Brass Press Fittings have a typical lifespan of 50 years or more. This is based on testing and real-world experience. 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. Brass Press Fittings can last 70+ years in cold conditions.
Lifespan in hot water
Hot water reduces lifespan slightly. At 140°F (60°C), lifespan is still 50+ years. At 180°F (82°C), lifespan is 30-40 years. Brass Press Fittings hot water life depends on temperature.
Effect of temperature on lifespan
Higher temperatures accelerate O-ring aging. Each 10°C increase reduces lifespan. At 20°C, lifespan is over 100 years. Brass Press 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. Brass Press Fittings are designed for 50-year life at rated pressure.
Effect of water quality
Aggressive water can affect the material. Brass is resistant to most water chemistry. Fittings maintain integrity in normal water. Brass Press Fittings are compatible with most water qualities.
Effect of O-ring material
The O-ring material affects lifespan. EPDM lasts 20-30 years. HNBR lasts 20-25 years. FKM lasts up to 30 years. Brass Press Fittings lifespan depends on the seal.
Effect of mechanical damage
Impact damage reduces lifespan significantly. Scratches or cuts weaken the material. Brass Press Fittings require careful handling.
Example: residential hot water system
A home uses Brass Press Fittings for hot water at 140°F. The system operates at 4 bar. The fittings are expected to last 50+ years. Example: a lifetime investment.
Example: commercial building plumbing
A commercial building uses Brass Press 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. Brass Press Fittings should last 70+ years. Example: a long-term reliable system.
Final lifespan summary
Brass Press Fittings have a typical lifespan of 50+ years. Cold water systems can last 70+ years. Hot water at 140°F lasts 50+ years. O-ring material affects lifespan. Pressure and water quality also affect lifespan. With proper installation and protection, Brass Press Fittings provide decades of reliable service. Example: a wise investment for any building.
