The diameter of the hose (or pipeline) that the sprinkler is designed to connect to, in other words, the diameter of the mounting thread provided in the device. This parameter allows you to determine compatibility with a specific hose: if the mounting diameters do not match, you will not be able to connect the sprinkler directly, you will need an adapter.
Hose diameters are traditionally indicated in inches — for example, 3/4" or 1.5".
The main material used in the construction of the sprinkler.
—
Plastic. The key advantages of plastic are its low cost and ease of processing, making it well suited for complex shaped parts. In addition, this material is lightweight and completely corrosion resistant. On the other hand, plastic is less durable and reliable than metal, and is less suitable for rubbing and other parts in contact with each other. However, in the case of sprinklers, this moment is not critical, and most modern models are made of plastic.
—
Metal. Metal favorably differs from plastic in higher strength and, theoretically, durability. On the other hand, it weighs more and is much more expensive; in addition, water-resistant alloys and/or coatings must be used in sprinklers, which further increases the cost. Therefore, this material is used relatively rarely — mainly in fairly advanced
models of the impulse type(see above).
— Metal / plastic. A combination of the two materials described above: usually, the most critical elements are made of metal, while the rest of the device uses plastic. This design allows you to combine the advantages of both materials and partially compensate for their shortcomings: metal-plastic sprinklers are not as expensive and heavy as all-metal ones, and at the same time more durable and reliable than plastic ones. This option is very popul
...ar, especially in models of the middle and upper classes.
