There are six stages to completing a joint using Polysure fittings.

 

Unlike the other Polypipe systems, Polyplumb and Polyfit, the Polysure system requires some specialist pressing tools which can be purchased directly from Polypipe or via the manufacturers stockists. Polypipe recommends using REMS pressing equipment who have a reputation for manufacturing durable products that can stand up to today’s site conditions.

Cutting pipes

Step 1:

Firstly check that the pipe is not scored or scratched in any way and if it is so cut back to a point where there is no damage present. Pipes should be cut squarely using an approved Polypipe cutter. There is a visual indicator on each fitting which is used to check that the pipe has been inserted into the fitting correctly, therefore, it is not essential that pipes are cut on the K marks. It is however essential that pipes are cut squarely as this may affect chamfering.

 

 

Chamfering the pipes

 

Step 2:

Polysure fittings use press fit technology which seals on the pipe bore so it is necessary to provide an internal lead in on the pipe end so the square edge of the pipe does not damage the ‘O’ ring seals. On push fit fittings this lead in is provided by the pipe stiffener. Polypipe offer specific pipe chamfering tools for our Polyplumb and Polyfit pipes and these must always be used. The chamfering tools are available in either individual tools or as a block of four dependent on the installers preference however all work in the same way.

 

The chamfer tool spigot should be inserted into the bore of the pipe until contact is made with the blades then the chamfer tool should be twisted gently to provide a lead in as shown. Any debris should be removed from the pipe end and the chamfer tool. Check that the pipe has been cleanly chamfered around the full diameter of the pipe. If not repeat the chamfering process again.

   

 

 

Insert pipe into fitting

 

Step 3:

Polysure pipes have a visual indicator to assist in jointing pipes and fittings together. The chamfered Polyplumb or Polyfit pipe should be inserted into the Polysure fitting and pushed in until the pipe can be seen through the hole in the stainless steel pressing sleeve. When this has been achieved the joint is ready for pressing.

 

 

 

Preparing the pressing tools

 

Step 4:

There are two types of pressing tool recommended for jointing Polysure fittings. The REMS Eco Press is a manual pressing tool which can be used on 10mm, 15mm and 22mm joints only but provides the installer with a light weight, low cost entry pressing tool which can be used in most situations. Alternatively the battery operated tool can be used where a high volume of joints needs to be done in a short space of time. The battery operated tool must be used for 28mm fittings.

 

The 10mm,15mm and 22mm Polypipe TH pressing jaws have been designed to fit both the manual and battery operated pressing tools. These jaws are also specifically designed to press Polysure press fit fittings and should only be used for these fittings. Likewise no other pressing jaw should be used for Polysure fittings.

 

Manual pressing tool

Step 4a:

Secure the jaw in the tool by firstly removing the locking pins from the Eco Press, lining up the holes in the Eco Press with those in the jaw and re-inserting the locking pins.

Step 4b:

To insert a Polypipe TH jaw into the battery operated gun, press the release catch on the locking pin on the gun. Slide the jaw into the gun aligning the centre hole in the jaw with the locking pin and push the locking pin back into position until locked.

 

Once the jaws are locked in the respective machine the pressing tools are now ready to complete the joint process.
