Basic Jointing/Pipe Cutting

When cutting Hep2O pipe it is essential to use the correct tools. Only the recommended cutters as shown in the price list (HEP74) should be used. Do not use a hacksaw. (Figure No. 1)

Before making a joint, ensure the pipe end is clean, cut square and free from burrs and surface damage. (Figure No.2).

Place the pipe in the jaws of the cutter and apply pressure. The pipe should be rotated whilst maintaining the pressure until the pipe is severed. (Figure No. 3)

To ensure adequate insertion, essential for a secure joint, cut the pipe square at one of the cutting/insertion marks ^ (Figure No. 3). The distance between these marks indicates full socket depth. When it may not be possible to use the ^ marks eg. badly lit areas, jointing copper pipe or where an exact length is required, mark the insertion depth on the pipe using a pencil or suitable marker pen.

The correct insertion depth can be obtained by holding the pipe against the fitting or by measuring with a ruler, as shown in Figure No. 4. The depth of insertion is shown in Table 3 at the end of this section.

Support Sleeve

ALWAYS insert a Hep2O support sleeve (HEP60) into the pipe end. (Figure No. 5) It is essential to use a support sleeve in order to make a good joint.

Failure to use a support sleeve will negate the guarantee (the only exceptions to this rule are when using copper pipe, or the spigot end of a Hep2O fitting).

ALWAYS insert a Hep2O Support Sleeve

Pipe Insertion: When using Demountable Hep2O BiTite fittings, DO NOT slacken the retaining cap prior to pipe insertion. This will not ease jointing. Push the pipe and fitting firmly together (Figure No. 6).

Do not knock the fittings onto the pipe (Figure No. 7). A secure professional joint has been achieved when the socket of the fitting has reached the next '^' mark (or pencil mark) on the pipe.

As a final precaution, after jointing it is recommended that, whilst holding the fitting firmly, the pipe is tugged back to check that the joint is secure. (Figure No. 8)
