Our high - quality PEX - AL - PEX tubing stands out for its precision engineering and exceptional performance. With a robust aluminum core neatly sandwiched between inner and outer layers of high - density polyethylene, its unique three - layer structure combines the flexibility and chemical resistance of polyethylene with the strength and barrier properties of aluminum, making it a perfect choice for various applications, especially radiant heat systems. Capable of handling a maximum working pressure of 175 psi and compatible with compressed air and water, it ensures reliable performance in pneumatic tool systems, plumbing, and irrigation setups. Its versatility shines through as it can be installed on walls, underground, or embedded in concrete, adapting to different piping needs.
