Polyethylene Reducer Fitting
One of the key fittings in plumbing systems with polyethylene pipes is the polyethylene reducer coupler. This fitting allows two polyethylene pipes of different sizes to be joined together.
Features of Polyethylene Reducer
- High resistance: It is resistant to corrosion, UV rays and pressure up to 10 bar.
- Easy installation: It can be installed easily and without special tools.
- Proper sealing: It creates a suitable sealing system for connecting polyethylene pipes to each other.
- Long life: Due to the polypropylene material of the fitting, it has a long life.
- Resistance to chemicals: This fitting is resistant to most acids and chemical fertilizers.

Product Application
Polyethylene Reducer Applications
This fitting is used to connect polyethylene pipes of different sizes to each other without welding and is used in irrigation systems and various industries. Considering the design of piping networks and considering hydraulic and economic characteristics, it is necessary to reduce the size of the pipes in different places. This fitting is responsible for connecting these pipes of different sizes to each other.
Benefits of Using Polyethylene Reducer
- Speed and ease of installation: Given that this type of fitting does not require welding, its installation is very quick and easy.
- Low cost: The male fitting is installed in less time and costs less than other connection methods.
- Light weight: The lightness of this fitting, in addition to making it easy to transport and maintain, also makes it easy to install.
Product Components
Fitting components
Reducer Fitting Components: The polyethylene conversion interface has components on both sides, each of which has a function, and the correct arrangement and shape of them ensure accurate sealing of the connection. These components include: the fitting body, the sealing ring, the split ring bushing, and the fitting screw.
The arrangement of these components is shown in the figure below:
Important points for installing polyethylene reducer
- Tightly tightening the nut: The conversion fitting nut must be tightened sufficiently to prevent leakage.
- Placement order: Observing the placement order of the fitting components is the main condition for sealing the conversion fitting.
