Which type of plastic pipe allows for stab type insertion joints?

1. PVC plastic pipe

2. Polyethylene plastic pipe

3. ABS plastic pipe

4. Polypropylene plastic pipe

The correct answer is: Polyethylene plastic pipe

Polyethylene plastic pipe is designed to accommodate stab type insertion joints, which are connections made by inserting one pipe end directly into the fitting without the need for special tools. This feature is particularly beneficial in various plumbing and gas distribution applications, where ease of installation and reliability are paramount. Polyethylene's flexibility and strength enable it to be connected quickly and efficiently using these types of joints, making it a preferred choice in many installations. This capability allows for a more streamlined assembly process, as the connection is made directly and securely, ensuring a good seal without the complications of threaded connections or additional fittings.
