Fittings for PEM

LK PressPex fittings are type-approved TG1652 and can be used for PEM-pipes in dimensions 16, 20, 25, and 32 mm with pipe dimensions as shown in the table below. All water-affected parts of LK PressPex are made of DZR (dezincification-resistant brass). The fittings must not be placed in the ground.

LK PressPex are delivered with a nickel-plated body in dim 16 and 32, and 20 and 25 are delivered with a yellow body.

Leakage indication is available on press fittings dimension 16 - 32 mm.

In order to check that a press fitting is compressed, a tightness check must be carried out before the final pressure test is performed with 1.43 x the calculation pressure (14.3 bar for tap water systems). Pressurize the pipe system to a test pressure of 3 bar for at least 30 minutes. All joints must be inspected. The pressure must not decrease during the control period. Read more about tightness testing in the LK assembly instruction flr LK PressPex.

See assembly instructions for pressing with LK PressPex connections. For the range of press machines and jaws please refer to the separate product catalog: Press tools

NOTE! To save time when installing, the press steps can be left so that a greater amount of compressions are made in a row. In these cases there is a great risk that the pipe ends partially slip out of the connection or that some connections do not get compressed. A careful check should therefore be made to avoid leakage.

LK recommends joint free pipe-in-pipe systems between visible connection points or placing the connection points in spaces with leakage indication. A joint free installation is always the safest option.

This range includes both PressPex fittings for universal (gray plastic ring) and PV (red plastic ring) corresponding to the dimension of the PEM pipe.

Designation Refers to connection for pipe dim. Color plastic ring on clutch
16 16 x 2,0 Gray
20 20 x 2,0 Red
25 25 x 2,3 Red
32 32 x 3,0 Gray
