Axial press machines

The axial press for sliding-sleeve joints REMS Ax-Press makes sliding-sleeve connections on water and heating pipe systems. The pressing stroke runs along the pipe axis, and the joint seals through material deformation, without a gasket. This page brings together 56 codes, grouped by drive unit and compression head. The 22V cordless version includes 573020 R22, diameter range 12 – 40 mm, 40 mm stroke. The hand-operated versions are 574300 RX and 574302 R, 66 mm stroke, with rapid advance and rapid return.

Compression heads are grouped by fitting system AT, Basic, HC, IV, LR, ME, RE, RH, RO, RV and by pipe size, packed in pairs. Pre-assembled sets combining machine and compression heads include 574010 R and 574304 R. The content below suggests choosing the drive unit first, then selecting the compression head by system and pipe size. Genuine REMS goods, imported, distributed with warranty.

An axial press for sliding-sleeve joints is used to make sliding-sleeve type connections on water and heating pipe systems. The working principle is based on a pressing stroke along the pipe axis. The sleeve is pushed along the pipe body and clamped onto the fitting body. The resulting joint uses no gasket and seals by the principle of material deformation. This product group brings together REMS Ax-Press drive units together with the matching pairs of compression heads, 56 codes in total.

The machine section covers 22V cordless versions and hand-operated versions. The cordless version includes 573020 R22 for the diameter range 12 – 40 mm, 40 mm stroke. The hand-operated versions are 574300 RX and 574302 R, 66 mm stroke, with rapid advance and rapid return. The compression heads are divided by fitting system: AT, Basic, HC, IV, LR, ME, RE, RH, RO and RV. Each system is further divided by pipe size, from 12 mm to 40 mm.

The compression heads are packed in pairs; the IV line is packed as three pieces. This grouping helps buyers narrow down quickly: choose the drive unit first, then select the compression head according to the fitting system and pipe size being installed. Sets that already combine machine and compression heads are also in the group, for example 574010 R and 574304 R. The pages below list each code together with the manufacturer's original description, convenient for cross-checking against the technical catalogue before ordering.

22V cordless drive units

The 22V cordless line serves mobile work, with no need for a power source at the installation point. The electro-hydraulic drive mechanism creates the axial pressing stroke. This group is divided by stroke and clamping distance, and also by packaging: bare machine in a carton, or a Basic-Pack placed in an L-Boxx. The installer chooses according to whether a battery and charger are already available.

Version 573020 R22 makes sleeve joints of diameter 12 – 40 mm, 40 mm stroke, maximum clamping distance 82 mm. Version 573021 R22 has a clamping distance of 116 mm and is supplied as a drive unit without battery and charger. Both codes accept REMS Pressköpfen compression heads.

The sets packed in an L-Boxx include 573039 R220 for the Ax-Press 25 version and 573041 R220 for the 25 L version. Code 573040 R22 also belongs to the Basic-Pack configuration in an L-Boxx. The Ax-Press 30 line comprises drive unit 573008 R22 and Basic-Pack 573037 R220.

Hand-operated drive units

The hand-operated version is used for occasional jobs or when battery dependence is not wanted. The lever mechanism generates the axial pressing force, combined with rapid advance and rapid return to reduce the time per joint. The diameter range and stroke differ from the cordless version, so cross-checking is needed before matching compression heads.

Code 574300 RX makes sleeve joints of diameter 12 – 32 mm with a 66 mm stroke. Code 574302 R is the one-hand type, range 12 – 22 mm, also with a 66 mm stroke. Set 574010 R comes with UNI compression heads in sizes 16, 20, 25, 32 and TL.

Sliding-joint compression heads by fitting system

The compression head mounts directly on the Ax-Press axial press and determines the shape of the joint. Each fitting system on the market has its own sleeve profile, so compression heads are also grouped by system. Selecting the correct system designation and the correct pipe size is the condition for the sleeve to slide through the full stroke and clamp at the right position on the fitting body.

AT, Basic and HC systems

The AT system has four sizes: 573122 for 20 pipe, 573124 for 25 pipe, 573126 for 32 pipe and 573128 for 40 pipe. The Basic system has 573624 in size 20 and 573628 in size 32. The HC system comprises 573114, 573116 and 573118, corresponding to sizes 20, 26 and 32.

IV, LR and ME systems

The IV system is packed as three pieces per set, comprising 573325 for size 20-21, 573330 for size 25-26 and 573335 for size 32-33. The LR system spans four consecutive sizes: 573432, 573434, 573436 and 573438, namely 22, 25, 28 and 32 mm.

The ME system covers a wider range towards the smaller sizes. Code 573102 is for 16 pipe, 573106 for 20 pipe, 573108 for 26 pipe and 573110 for 32 pipe. All of the above codes are packed as pairs of compression heads.

RE, RH, RO and RV systems

The RE system comprises 573162, 573172, 573178 and 573176, covering sizes 20, 25, 32 and 40 mm. The RH system has the densest size coverage, from 573164 in size 12 to 573156 in size 32, together with 573166, 573168 and 573170.

The RH 20 L version carries code 573152, listed separately from the standard RH 20 version. The RO system currently has 573186 for 20 pipe. The RV system comprises 573402 in size 20 and 573404 in size 25. When ordering, state both the system designation and the size number to avoid mixing up profiles that are close to each other.

How to narrow down your selection

The selection sequence should start from the diameter range of the work. If the pipe system runs up to 40 mm, the cordless Ax-Press 25 version covers the range 12 – 40 mm. If the work only goes up to 22 mm and is occasional, the one-hand version 574302 R is more compact. The next step is to identify the fitting system used on site, then take the correct compression head size.

Clamping distance also needs consideration when the joint sits close to a wall or inside a service duct. Version 573020 R22 has a maximum clamping distance of 82 mm, while version 573021 R22 reaches 116 mm. For those building up a tool set for the first time, the Basic-Pack configurations in an L-Boxx gather machine and accessories into one case, convenient when moving between work positions.

You can view the details of each code in the list below to cross-check diameter range, stroke and packaging. If you need to match a drive unit with the correct compression head system, send us the fitting system and pipe size you are using for advice on a suitable configuration.
