MAGNAPLAST telescopic sleeve (manszeta) for smooth riser pipe RWK 425 mm, model 35611

The MAGNAPLAST telescopic sleeve (manszeta) model 35611 is an adjustable connector intended for smooth riser pipe RWK with a nominal 425 mm length. It is designed to join adjacent riser pipe sections, create a sealed transition and allow a degree of axial movement to accommodate thermal expansion or minor alignment differences. The component is intended for use in plumbing and drainage assemblies where RWK smooth riser pipes are specified.

Advantages

This telescopic sleeve provides a secure, sealed joint between riser pipe sections while permitting limited telescoping movement to absorb thermal changes and installation tolerances. Its adjustable design reduces the need for precise pipe-to-pipe fitting on site and helps maintain system tightness over time. The product is compatible with RWK smooth riser pipe dimensions and is made to integrate into standard plumbing and drainage layouts.

Suitable for (tasks / use cases)

• Connecting and sealing adjacent sections of RWK smooth riser pipe with nominal 425 mm length
• Drainage and soil stack installations in residential and commercial buildings
• Applications where slight axial adjustment or thermal movement compensation is required
• Replacement or repair of existing riser joints without full pipe realignment

When it may not be suitable

The telescopic sleeve is intended specifically for RWK smooth riser pipe systems and nominal lengths around 425 mm; it may not form a reliable connection with pipes of different profiles, materials, or significantly different diameters. For systems requiring high structural load-bearing, rigid fixed connections, or where large directional offsets must be corrected, a different coupling or fitting should be chosen.

Key specifications

• Type: telescopic sleeve for smooth riser pipe
• Compatible pipe system: RWK smooth riser pipe
• Nominal length: 425 mm (installation length reference)
• Function: adjustable sealing and axial movement compensation
• Application area: plumbing and drainage riser connections

How to use

Prepare the mating pipe ends by ensuring they are clean and free of debris. Slide the telescopic sleeve over one pipe end and align the adjacent section to achieve the required overlap. Adjust the sleeve to obtain a tight fit and proper sealing contact with both pipe surfaces. Follow standard installation practices for RWK riser systems, ensuring seals or gaskets are seated correctly and any retaining elements are secured according to local codes and manufacturer guidance.

What to consider before purchase

• Verify compatibility with the specific RWK smooth riser pipe profile and diameter used in your project
• Confirm that a 425 mm nominal length sleeve meets the required overlap and adjustment range for your installation
• Check local plumbing codes and system requirements for materials and joint types

Usage recommendations

Install in dry, clean conditions and inspect seals after initial system testing. Use compatible sealing lubricants if recommended by pipe manufacturer and perform pressure or leak tests following installation to confirm joint integrity.
