How to choose pipe fittings: Easy Answers

Fittings are an optional connection in the pipeline. It is intended for changing the configuration of the water pipe, fixing two products from different materials. So, this part can create a corner of the plumbing, form a pipe branching into several channels, etc.

The correctly selected fitting determines how long the communication system or a specific connection will serve. Due to the large assortment, it can be difficult for an inexperienced user to choose a coupling for a specific network.


The main task of fittings is to establish a strong, durable and airtight pipe connection. The organization of internal communications of the premises has its own requirements. Therefore, there are several classifications of fittings.

By connection method:

Crimp – with a special fixation mechanism;

Welded – to create a node, the ends of the pipes must be welded;

Threaded – connect pipes of a certain diameter, are made of steel.

By functionality:

  • Adapters;
  • Corner fittings;
  • Unidirectional couplings;
  • Plugs, plugs, caps;
  • Fittings for plastic rubber hoses;
  • Dividers – tees, crosses, collectors.

The main rule for selection and installation of sprinklet socket malaysia is that the materials of the pipes to be connected and the fitting must match. If it is necessary to connect pipelines of different types, adapters are used for this: squeegees, nipples, fittings.

It is important to mention the methods of mounting the fitting to the pipes. The type of connection of the fitting largely depends on how long the water supply system will be used. Distinguish:

Threaded – designed for metal and metal-plastic pipes, the most common type;

Removable – used for polymer pipelines, can be installed and removed several times;

Press connections – such units are created mechanically using a special press and have the highest reliability.

Principles of using fittings in work

The fittings are designed to allow any variation of installation. This greatly facilitates the selection of the necessary elements and allows you to carry out work of any complexity. In order to better understand the possibilities, consider the principles that should be followed when working with fittings.

According to the method of fastening, fittings are divided into:

  • Press fittings ;
  • Compression fittings ;
  • Tension fittings ;

Before proceeding with the installation, it is necessary to draw up a carefully thought out plan, which will show the dimensions and fastenings, turns and forks of the pipeline. It is also required to prepare tools and materials – the pipes must fit in size, their edges are aligned and cleaned from irregularities and burrs. Fittings must be selected according to configuration, method of attachment and quantity.

Installation using compression fittings

Using compression fittings is a fairly simple task that even a non-specialist can easily cope with. The second advantage of this fastening is its simple interchangeability – at any time you can change a pipeline element at any site equipped with this type of fastening.

Installation using compression fittings

For some types of work, it is advisable to use crimp fittings, for example, when laying communications inside a wall or under a floor covering. Due to their more rigid fixation and non-separable design, compression fittings have won the fame of more reliable fastenings.
