PPSU (Polyphenylsulfone) PEX-A PEX fittings are a type of plumbing fitting used in PEX piping systems. PEX-A (cross-linked polyethylene) is a flexible and durable material used in residential and commercial plumbing applications. PEX-A is a specific type of PEX that is cross-linked using the peroxide method.
PPSU PEX-A PEX fittings are made of a high-performance thermoplastic material called polyphenylsulfone (PPSU). PPSU is a type of plastic that is known for its excellent chemical resistance, high temperature tolerance, and toughness. PPSU PEX-A PEX fittings are ideal for use in applications where the water or fluid being transported may be corrosive or contain high levels of chlorine, such as in industrial or commercial settings.
Some common types of PPSU PEX-A PEX fittings include:
Couplings: Used to connect two PEX-A pipes together.
Elbows: Used to change the direction of PEX-A piping.
Tees: Used to create a branch in a PEX-A plumbing system.
Adapters: Used to connect PEX-A piping to other types of piping, such as copper or PVC.
When selecting PPSU PEX-A PEX fittings, it is important to ensure that they meet the appropriate standards and regulations for drinking water applications. The fittings should be certified to NSF/ANSI 61, which verifies that they do not contain harmful levels of contaminants. It is also important to ensure that the fittings are compatible with the specific type of PEX tubing being used, as some fittings may only be compatible with certain types of PEX.
Some of the features of PPSU PEX-A PEX fittings include:
Chemical Resistance: PPSU is highly resistant to chemicals, making it ideal for use in plumbing systems where the water or fluid being transported may be corrosive or contain high levels of chlorine.
Temperature Resistance: PPSU can withstand high temperatures up to 180°C (356°F), making it suitable for use in hot water applications.
Toughness: PPSU is an extremely tough material that can withstand impact and pressure without cracking or breaking.
Easy to Install: PEX-A tubing and fittings are easy to install and require fewer connections than traditional copper or PVC piping systems, reducing installation time and costs.
Corrosion Resistance: PPSU is naturally resistant to corrosion, making PPSU PEX-A PEX fittings ideal for use in plumbing systems.
