1. What is PP Compression Fittings?PP SADDLE +PP WATER TANK

PP compression fittings are mechanical joint fittings, which is made of polypropylene. They provide a convenient and reliable method for joining pipes without the need for specialized tools or equipment.

The fittings are typically made from high-quality polypropylene material, known for its durability, chemical resistance, and excellent seal performance under pressure. For many years, PP compression fittings have been widely used in agricultural system, drinking water supply and other pipeline systems. The overall demand in the global corresponding market is large and increasing year by year.

2. How Does PP Compression Fittings Work?

PP compression fittings consist of three main components: a compression nut, an O-ring, and a compression body. The three components create a secure and leak-proof connection between pipes and fittings. These fittings allow for a quick, simple insertion of the tube, considerably reducing installation time: simply loosen the nut (without removing it), and insert the pipe.


3. What are the advantages of pp compression fittings?

3.1. Easy Installation

Different from traditional metal piping system, PVC piping system and HDPE piping system, it does not require welding, soldering or adhesive bonding. End user simply loosen the nut without removing it and push insert the pipe which is considerably reducing installation time

3.2. Easy to disassemble

PP compression fitting can be easily disassemble if there has been an error in installation or removal is required. Especially for irrigation application, after one season finished, farmer need to disassemble and install again in next season. It is very easy and simple.

Importantly, if removal is required, there is only minimal need for new pipe and fitting. The installer remove the existing fitting by losing the nut and replace with a new one providing the pipe is not damaged.

3.3. No tools required

PP compression fittings is call push fit fittings also. It require no additional tools for installation. Once cutting, measuring and deburring of the pipes has been undertaken, end user can joint pipe and fittings within seconds.

3.4. Perfect for installing in confined spaces

PP push-fit fittings are particularly suitable for use in tight spaces. When space is limited, HDPE or PVC pipeline installers are unable to weld or adhesive bonding correctly, but PP push-fit fittings can be installed very conveniently and effortlessly.

3.5. Flexibility and Versatility

Another advantage of PP compression fittings is their ability to accommodate pipe movement and expansion. The fittings allow for a certain degree of flexibility, which is beneficial in applications where pipes may shift or experience thermal expansion and contraction. And this is the main reason we can use pp compression fittings with other plastic pipe.

3.6. Durability and Chemical Resistance

PP compression fittings are highly durable and resistant to corrosion and chemical degradation. They can withstand a wide range of temperatures, making them suitable for both hot and cold water applications. Additionally, the fittings are resistant to common chemicals found in plumbing systems, ensuring long-term performance and reliability.


4. Applications:

PP compression fittings find applications in various plumbing and irrigation systems, such as:

•      Residential and commercial plumbing networks

•      Irrigation systems for gardens, parks, and agricultural fields

•      Swimming pool plumbing and filtration systems

•      Industrial setups requiring chemical-resistant connections
