PEX-B is a type of PEX tubing that is made using a silane method of cross-linking polyethylene. This method involves adding a cross-linking agent to the polyethylene, which creates a chemical bond between the polymer chains and forms a strong and durable material. PEX-B tubing is often used in plumbing and radiant heating systems because of its flexibility, resistance to corrosion, and ease of installation.
PEX fittings, on the other hand, are the connectors used to join sections of PEX tubing together or to other plumbing components such as valves, fixtures, and manifolds. PEX fittings are available in a variety of materials, including brass, copper, and plastic, and come in different types such as crimp, clamp, and push-fit.
When using PEX-B tubing, it is important to choose compatible PEX fittings to ensure a secure and leak-free connection. The type of PEX fitting used will depend on the specific application and the type of PEX tubing being used. It is important to follow the manufacturer's guidelines for both the PEX tubing and fittings to ensure a proper installation.
PEX-B is a type of cross-linked polyethylene tubing that is commonly used in plumbing and heating systems. There are several types of PEX-B fittings available, including:
Crimp fittings: These fittings have a metal ring around the outside of the PEX tubing, which is crimped with a special tool to create a watertight seal.
Clamp fittings: Also known as "cinch" fittings, these use a stainless steel clamp to secure the PEX tubing to the fitting. They are typically easier to install than crimp fittings and require only a simple tool.
Push-to-connect fittings: These fittings have a mechanism that allows the PEX tubing to be pushed into the fitting, creating a secure connection without the need for any special tools or crimping.
Compression fittings: These fittings use a threaded nut and ferrule to compress the PEX tubing onto the fitting. They are typically used in situations where a removable connection is needed.
Expansion fittings: These fittings use an expansion tool to stretch the end of the PEX tubing, allowing it to slip over the fitting. When the tubing cools and contracts, it forms a tight seal around the fitting. These fittings are commonly used in larger diameter PEX tubing.
Valve fittings: These fittings incorporate a valve into the design, allowing for easy shut-off of the water supply to a specific area or appliance.
PEX-B fittings are known for their durability, flexibility, and resistance to corrosion and chemical damage. Here are some of their specific characteristics:
Toughness: PEX-B fittings are made from a high-density polymer that is resistant to cracking and splitting, making them a popular choice for plumbing and heating systems.
Flexibility: PEX-B fittings are highly flexible, which makes them easy to install in tight spaces and around corners without the need for additional fittings.
Heat resistance: PEX-B fittings are capable of withstanding high temperatures, making them ideal for use in hot water systems.
Corrosion resistance: PEX-B fittings are resistant to corrosion, which helps to prevent leaks and other forms of damage over time.
Chemical resistance: PEX-B fittings are resistant to a wide range of chemicals, making them a good choice for use in chemical processing plants and other industrial applications.
Cost-effective: PEX-B fittings are generally more cost-effective than other types of plumbing fittings, making them a popular choice for both residential and commercial plumbing systems.
