Wavin press-fittings: characteristics and installation features

Piping systems that are connected by means of press fittings are gaining popularity, because they can be used for flush mounting of pipeline, they can be used even when mounting pipes into concrete, which greatly expands opportunities for the design of underfloor heating systems.

Wavin Future K1 multilayer pipe system is made of durable and chemically-resistant material, it can be used for transportation industrial water or liquid food products.

Installation of Wavin press fittings

	1. Cut the pipe to the required length.

	2. Calibrate the pipe with a manual or electric tool (rotation speed - not more than 500 rev/min). This must be done for removal the chamfer and giving of the pipe ends a round shape - this will minimize the chance of damaging the O-rings during installation and allow to insert of the pipe into the Wavin fitting easy.

	3. Push the pipe into the fitting until it is visible in the window.

	4. Press the fitting through a manual or electric tool.

During installation of the pipeline system you should use only those tools that meet the requirements of Wavin. The pressing process must be executed only once per connection - there should not be repeated operations because this leads to damage of the joint.

Also you should remember that the Wavin Future K1 pipes and fittings do not require the use of lubricants or additional sealing rings during installation.

Hydraulic fittings resistance

The table below shows the approximate values of the coefficients of local hydraulic resistance of Wavin press fittings.
