MLC pipe Fittings & Tools Concept
Uponors range of fittings, consisting of couplings, elbows, tees and a large number
of other system components leaves nothing to be desired: Pressing or screwing –
both methods can be used to ensure a permanently tight connection. With the advanced
press fitting generation, Uponor is offering a multi-layer composite pipe system
with reliable test safety. The fitting is designed so that pressure testing reveals
non-pressed connections which would discharge water – a smart system designed for
your safety. An additional bonus is the clever range of tools for fast and convenient
installation.
 Connection
By Screwing
Uponor screw fittings are available for diameters from 12 to 25 mm and fit all Uponor
nipples, elbows, tees, transitions and manifolds. For example, a tee can be formed
into a reducing tee by combining various different sized pipe screw fittings with
identical threads. The system reduces warehousing costs and facilitates ordering
procedures.
Connection By Pressing
Press fittings are available for all practical applications. Press fittings of tin
plated brass are available for all sizes from 12 to 75 mm. The system also includes
composite fittings of PPSU in the sizes 16 to 32 mm. Specially developed clamp fittings
are available for diameters 90 and 110mm.
Pressure sleeve of metal fittings
The pressure sleeve for dim. 16-32 mm of high quality aluminium is permanently connected
with the fitting body. That means the O-rings are protected against mechanical effects
during transport and handling. The integrated window enables a check to be made
during installation to see whether the pipe is correctly inserted.
 Uponor
Pressing Tools
Uponor pressing jaws are designed specially for use in conjunction with Uponor electrical
and battery-operated pressing tools.
In case pressing tools of other make will be used the respective manufacturer should
be contacted in order to approve the qualification, warranty and operational safety.
A range of clever tools from pipe cutters to bevelling tools rounds off the MLC
pipe system.
PEX Fittings & Tools Concept
Uponor PEX pipe is manufactured to BS7291 Class S, for use with Uponor PEX fittings
– the unique system concept from Uponor.
Uponor PEX fittings are available in selection of PPSU plastic fittings and DZR
brass fittings. The Uponor PEX joint is formed due to the unique elasticity of Uponor
-PEX and the final joint is as strong as the pipe.
Uponor PEX pipe can also be used with compression fittings which conform to BS EN
1254 when used together with the Uponor pipe insert. This gives the installer the
choice to use a traditional jointing method.
 Uponor
PEX Fittings
Uponor PEX pipe can be joined using the unique Uponor PEX system. The following
points must be strictly observed.
- All installations should be made by a Uponor trained and certificated installer.
- Always use the special Uponor PEX expander tool.
- Always use the correct sized PEX ring.
- Always use the correct sized PEX fitting.
- Please observe that the PEX joint needs longer waiting time before testing the joint
at lower temperatures (see Chapter 7).
- The Uponor PEX fitting must only ever be used with Uponor PEX pipe.
Uponor PEX Components
When making a Uponor PEX joint it is important to use the correct sized ring and
fitting, the correct sized expander head and not to exceed the maximum number of
expansions. Observing these requirements will ensure that a good joint is always
achieved.
An expansion tool with a choice of head sizes is available. Choose from a manual
or battery-powered tool.
