Polyfit System

Jointing

There are four stages to successfully jointing the Polyfit system.

Cutting Polyfit 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

Using an approved pipe cutter cut the pipe squarely using the "K" marks on the pipe as a guide.

Use of pipe stiffener

Step 2:

Insert a pipe stiffener into the pipe (not required on copper pipes).

Inserting pipe into fitting

Step 3:

Push pipe into the fitting, ensuring it is inserted to the full socket depth denoted by the next "K" mark on the pipe. Insertion depth markers on fittings Each fitting now has an insertion depth marker on the fitting body to aid with installation. The only way of being certain that a joint has been completed successfully is by using the insertion depth marks on the pipe for cutting and insertion purposes.

Checking the joint security

Step 4:

Tug back on pipe to check it is inserted fully.

Connecting Polyfit to copper pipes

Step 5:

Cut the copper pipe using a rotational pipe cutter. Mark the copper pipe insertion depth as shown in the table below. Follow steps 3 and 4 using the mark as a socket depth guide.

Demounting a Polyfit joint

Polyfit fittings are fully demountable and re-usable. To demount a Polyfit fitting simply depress the collet squarely towards the fitting and pull the pipe out of the fitting. When systems have been pressurised the collet is designed to grip into the pipe therefore using a fitting release aid (product code FITAID) will assist in demounting fittings.

System testing

Prior to completing installation it is necessary to fully test the installed system. Please refer to the section on system testing guidance for further details.
