Coupling, Repair and Sealing Sleeves for Pipes and Sewer Conduits

Coupling Sleeves, Type 2A (TC)

Ceramic pipe coupling and repair sleeves
Type TC, according to DIN EN 295 part 4, is used for joining or repairing ceramic pipe ends. These sleeves comply with European standards for sewer and stormwater applications up to 0.6 bar.

Coupling Sleeves, Type 2B (SC)

Universal coupling sleeves, 2B (115 mm to 620 mm)
Type SC according to DIN EN 295 part 4 is used for joining free pipe ends of all materials or for repairs up to OD 620 mm. Designed for sewer, stormwater and low-pressure applications up to 2.5 bar.

Coupling Sleeves, Type 2B (LC)

Universal coupling sleeves, 2B (601 mm to 2000 mm++)
Type LC according to DIN EN 295 part 4 is used for joining free ends of pipes above OD 620 mm. Custom diameters can be manufactured (example 621, 622, 623 mm).

Flexi Bushes

Flexi Bush Rings, BC Type
Designed to be used together with SC couplings when pipe outside diameters differ significantly. Available thicknesses: 4, 8, 12, 16, 24 and 32 mm. BC Flexi Bushes are manufactured from EPDM rubber profile according to EN 681-1, cut and vulcanized into ring form. These solutions can also be used when there is a reduction or expansion in diameter, for connecting free pipe ends.

Flexi Bushes

Flexring FR
A universal set of sleeves with flexi bushes for connecting any type of DN 100, DN 150 & DN 200 pipes. The Flexring combines three different bush thicknesses in one product, allowing the user to fold or cut it to connect two pipes with different outside diameters. This solution is ideal when the pipe types in the ground are unknown. For example, FR 100 can compensate 3 mm, 6 mm, or, when folded, 9 mm difference in outside diameters.

Couplings, Type 2B All-In-One

They can connect any type of pipe with the same nominal diameter, regardless of the actual outside diameter. Have you ever uncovered a pipe during excavation and found surprises regarding its type or dimensions? In such cases, when outside diameters differ, you would normally use an AC adaptor coupling or a standard SC coupling with adaptor bushes, if shear forces between the pipe axes are limited. The 2B ALL-IN-ONE coupling replaces both of these products.

Unicon Coupling, Type 2B

A universal coupling for connecting any type of pipe, regardless of material or surface structure, for a given nominal diameter. Each UNICON couples sewage or stormwater pipes, within tolerance, whether the contact surface is smooth or corrugated.

SCW Sleeves, Type 2B Extra Wide

The SCW type, compliant with DIN EN 295 Part 4, is approved for sewer system construction using any pipe type (up to 620 mm OD). Its 300 mm width provides greater tolerance when cutting pipe ends, as well as increased mobility during installation or thermal expansion.

LCW Sleeves, Type 2B Extra Wide

The LCW type, in accordance with DIN EN 295, Part 4, is approved for the construction of sewer networks using any type of pipe (from 620 mm OD and above). LCW couplings from 620 mm upwards are calculated according to the customer’s specifications and manufactured to order. Production is possible in 1 mm increments (for example: 621, 622, 623 ...).

Magnum Sleeves, Type 2B

The MAG type, in accordance with DIN EN 295, Part 4, is approved for the installation of sewer networks made from any pipe material (from 320 mm OD and above).
The 370 mm width ensures resistance at pressures up to 4.0 bar. The unique MAGNUM coupling system is designed for extreme applications, withstanding up to 4.0 bar depending on diameter. The MAGNUM coupling, with its 370 mm width, is the widest repair and coupling sleeve on the European market. This width provides greater tolerance and allowable deviation when cutting pipe ends, as well as increased flexibility during installation and pipe laying. In addition, larger cracks or holes can be repaired.

Internal Couplings, ICON

Innovative jointing technology
This is a unique coupling that seals the pipe on its inner wall, while the tightening clamp remains on the exterior. The EPDM rubber profile together with the tensioning mechanism ensures a secure and tight connection for pipes ranging from DN 150 to DN 400. In the past, it was not possible to join two pipes in the manner shown in the attached image in a safe and permanent way.

Internal Couplings, Pushfit

Pushfit internal couplings for pipes with different outside diameters
The newly developed range of internal couplings introduces a new product to the ICON family. The PUSHFIT internal coupling is used for joining plastic, cast iron and steel pipes that have different external diameters. The new Pushfit coupling enters only 52 mm inside each pipe end and reduces the flow section by less than 10%. It complies fully with the test requirements of DIN EN 295-4.

AC Adaptor Couplings

They are designed for connecting pipes made of any material that have different outside diameters, in compliance with DIN EN 295-4.
AC adaptor couplings ensure the transition between pipes of different materials and also different nominal diameters. These adaptors should be used only in situations where shear forces can be avoided, such as uneven compaction or traffic loads. When these parts are used, special attention must be paid to the direction of flow.

AR Adaptor Couplings

AR adaptor (ribbed / corrugated)
These are intended for connecting corrugated plastic pipes to any other pipe type and material that have different outside diameters, according to DIN EN 295-4. The AR range is a coupling solution that incorporates a special extra-wide clamp at one end. This clamp engages two or more ribs of the corrugated pipe, ensuring a high-quality joint that is not affected by pipe position changes or movement.

DC & PC Couplings

Type 1 couplings are intended for connecting pipes of any kind that have identical or similar outside diameters, according to DIN EN 295-4.
The Type 1 DC coupling is injection-moulded and equipped with medium-strength clamps at both ends. It is used in drainage systems where shear forces are absent and where no traffic loads act on the pipes. Available for outside diameters up to 275 mm.

Lateral Branch Saddle, PA

The PA lateral branching saddle is intended for PVC-KG pipes with an outside diameter of 160 mm that need to be connected to a double-wall corrugated main pipe with a diameter greater than DN 300. Five models are available: PA1530, PA1530UR, PA1540, PA1550, and PA1560. Each saddle is designed to connect DN 150 plastic pipes to the main pipeline ranging from DN 300 to DN 600.

Lateral Branch Saddle, TA

The TA type is designed for lateral branches DN 100, DN 150, and DN 200 to any thin-wall main pipe.
The TA saddle is a fast and economical solution for connecting PVC-U pipes or other types, with diameters DN 100, DN 150, and DN 200, to a smooth-wall main pipe of up to DN 600. The socket is made of high-quality EPDM, the collar is made of thermoplastic elastomer, and the metallic components are stainless steel W 1.4301 (V2A).
