In the renovation or repair of household water pipes, PEX fittings have become the choice of more and more people because of their advantages such as easy installation, strong durability and high cost performance. However, many people may ask: “Can I use pex fittings on polyethylene pipe?” The answer is: Yes, but you need to pay special attention!
Why is there such a question?
Although PEX (cross-linked polyethylene) and PE (polyethylene) are both polyethylene materials, their chemical structures and properties are different:
PEX pipes are cross-linked and have higher heat resistance, pressure resistance and flexibility, and are suitable for hot and cold water systems.
PE pipes are usually used in cold water systems or low-pressure scenarios, and their performance is not exactly the same as PEX pipes.
Therefore, directly using PEX fittings to connect PE pipes may result in loose sealing or loose connections, increasing the risk of water leakage.
Solution: How to safely connect PE pipe and PEX pipe?
Although you cannot directly connect PE pipe with PEX fittings, you can easily achieve a safe connection between the two by the following methods:
1. Use PE-PEX transition joint
This joint is designed to connect PE pipe at one end (usually using hot melt or electric fusion connection), and the other end is designed to connect PEX pipe (using compression or push-on connection).
Advantages: Strong connection, good sealing, suitable for long-term use.
Operation steps:
Use Welding Machine to connect PE pipe to the PE end of the transition joint.
Use PEX pipe clamp to connect PEX pipe to the PEX end of the transition joint.
2. Use threaded adapter
If both PE pipe and PEX pipe have threaded interfaces, you can use a threaded adapter to connect them.
Advantages: Simple installation, no special tools required.
Operation steps:
Wrap raw tape or apply sealant on the threads.
Use a wrench to tighten the adapter on the PE pipe and PEX pipe.
3. Consult a professional
If you are unsure of what to do, or have concerns about the safety of the connection, it is recommended to consult a professional plumber or supplier.
Pros: Ensures a safe and secure connection and avoids potential problems.
Why choose PEX pipe fittings?
1. Easy installation: No complicated tools and welding techniques are required, and installation can be completed using simple tools.
2. Strong flexibility: PEX pipes can be bent and easily bypass obstacles, reducing the number of joints and reducing the risk of water leakage.
3. Corrosion and high temperature resistance: PEX pipes are not easy to rust, have a long service life, and can withstand high temperature hot water.
4. High cost performance: Compared with traditional copper pipes, PEX pipes are more affordable and have lower installation costs.
Tips:
1. When purchasing transition joints or adapters, please choose regular brands to ensure quality.
2. Read the product manual carefully before installation to understand the installation methods and precautions.
3. If you are not sure how to operate, you can watch relevant video tutorials or consult professionals.
