VIEGA Viega 3815 pipe sleeve, inner diameter 100 mm, length 2500 mm

VIEGA Viega 3815 pipe sleeve with an inner diameter of 100 mm and a length of 2500 mm provides a protected passage for pipes through walls and floors. The sleeve is designed to guide plumbing, HVAC or electrical installations while maintaining a defined conduit that can accommodate movement and assist in creating fire stops when combined with appropriate sealing materials. Constructed from plastic and supplied with a lip seal, this model is intended for use where a durable, low-profile sleeve is required to protect pipe edges and simplify installation.

Advantages

The plastic construction offers corrosion resistance and low weight, facilitating handling and installation in confined spaces. The lip seal provides a basic barrier against dust and moisture and helps keep the pipe centered within the sleeve. With a 100 mm inner diameter and 2500 mm length, the sleeve supports long-run penetrations and ensures a consistent opening for later sealing, inspection or replacement of services. Its geometry is suitable for standard WC and sanitary installations as well as other pipe types within the specified diameter range.

Suitable for

• Routing sanitary pipework through walls and floors (including WC installations)
• Protecting pipe edges during building work and finishing
• Creating defined conduits for HVAC or electrical service runs
• Providing a channel for fire-stopping materials where required

Key specifications

• Inner diameter: 100 mm
• Length: 2500 mm
• Material: plastic
• Seal type: lip seal integrated
• Intended application: pipe sleeve for wall and floor penetrations

How to use

Cut the sleeve to the required length if necessary and insert it into the prepared opening in the wall or floor. Position the sleeve so that the lip seal aligns with the finished surface or the position specified by project requirements. Run the pipe centrally through the sleeve and ensure adequate clearance for movement and for the application of any fire-stopping or sealing materials. Secure the sleeve according to site practice to prevent displacement during subsequent works.

Usage recommendations

For installations requiring fire resistance, complete the penetration with approved fire-stopping systems compatible with plastic sleeves and the specific pipe material. Check local building codes for required clearances and sealing methods. When used in sanitary or WC applications, verify compatibility with the pipe outer diameter and ensure the lip seal is correctly seated to reduce ingress of debris or moisture.
