Polyethylene Reducing Coupling or coupling that has no equal diameters. Couplings that are applied in transmission line piping in order to connect two polyethylene pipes to each other, or in other words, the unequal coupling is applied in order to reduce or increase the polyethylene pipe, and also connects two pipes to each other and also connects smaller diameter pipe to a larger diameter pipe or vice versa, assume that you have a size 63 pipe, but you need to change its size to 40. It is just enough to add a 63 by 40 reducing coupling to the end of pipe 63 and install the opening of your pipe 40’s to it.
Accordingly, you are easily able to change the size of your water supply pipe.
These fittings are generally applied for irrigation systems and irrigation the agricultural lands and farms and they are highly needed in irrigation systems.
Advantages of polyethylene reducing coupling:
• It has a different size on both sides of the coupling in order to reduce or increase the size
• It is resistant to moisture and corrosion
• It has a complete seal utilizing the o-ring available in it
• It is resistant to pressure and impact
• Fast and easy connectivity
• It has a highly reasonable price compared to steel fittings and …
• It is light and easy to carry
In general, the components of the reducing coupling include:
Body: Polypropylene copolymer
Socket: Polypropylene copolymer
Split ring: Polyoxymethylene (POM)
Bushing: Polypropylene
O-ring: (NBR_SBR-EPDM) can be delivered upon the customer’s request.
