PPR管是当下家庭装修水路安装使用最多的一种主材，同时也需要用到很多的水管配件，对于选择半包或者自己装修的业主来说，这些材料都是需要自己去购买的，但是PPR的水管配件种类、型号繁多，往往由于不清楚使用特性和配件名称，买错配件或是不知道如何下手购买而造成诸多困扰。
PPR pipe is one of the main materials used most in the installation of waterways for home decoration at present. At the same time, a lot of water pipe fittings are needed. For the owners who choose half-pack or self-decoration, these materials need to be purchased by themselves. However, there are many kinds and models of water pipe fittings for PPR. Often due to unclear use characteristics and name of fittings, they buy wrong fittings or do not know how to go down. Hand purchases cause many problems.
弯头elbow
弯头指的就是用于管道转弯处的一种管件。由于水管本身是笔直的，不能弯折，若要改变水管的走向，只能通过弯头来实现，主要有45°弯头和90°弯头。有时候也会用到外丝和内丝弯头，外丝弯头又名阳口弯头、外螺纹弯头，内丝弯头又名阴口弯头、内螺纹弯头。内丝和外丝是连接龙头、水表以及其它类型水管时会用到的，通常是配套使用的，家装中主要会用到的都是内丝件。带丝接口的配件较贵，一个带丝接头有时比一米水管的价格都贵。
Elbow refers to a kind of pipe fittings used at the bend of pipeline. Because the water pipe itself is straight and can not bend, if you want to change the direction of the water pipe, you can only achieve it through the elbow, mainly 45 degree elbow and 90 degree elbow. Sometimes, the outer and inner elbows are also used. The outer elbow is also known as the Yang elbow and the outer thread elbow. The inner elbow is also known as the Yinkou elbow and the inner thread elbow. Internal and external wires are used when connecting faucets, water meters and other types of water pipes. They are usually used together. Internal wires are the main components used in household decoration. Ribbon joint fittings are more expensive, and sometimes a ribbon joint is more expensive than a meter water pipe.
直接bushing
又称为套管、管套接头。使用时要注意与水管的尺寸相匹配，当管道不够长时，可以作为连接两根管道的配件来延伸管子。
Also known as sleeve, sleeve joint. When using, it should be matched with the size of the pipe. When the pipe is not long enough, it can be used as an accessory to connect two pipes to extend the pipe.
三通three-way pip
分为同径三通和异径三通，是连接三个不同方向的水管用的，从一根水管中引出一条水路来的时候需要使用到。有时候也会用到外丝和内丝三通，外丝三通又名阳口三通、外螺纹三通，内丝三通又名阴口三通、内螺纹三通。
It is divided into the same-diameter three-way and the different-diameter three-way, which are used to connect three different directions of water pipes. It is necessary to use the same-diameter three-way and the different-diameter three-way when a water channel is drawn from a water pipe. Sometimes we also use outer and inner threads. The outer threads are also called Yangkou and outer threads. The inner threads are also called Yinkou and inner threads.
