Rawiplast universal extendable connector 5/4" (B310) for plumbing and drainage

Rawiplast universal extendable connector 5/4" (B310) is a plumbing accessory designed to join plastic pipe sections and fittings with a nominal 5/4" diameter. The connector features an adjustable length mechanism for precise alignment during installation and provides a mechanical joint suitable for drainage, waste and soil systems in household and light commercial environments. Constructed to work with common plastic plumbing materials, the part supports reliable connections between fixtures and pipes where small axial adjustments are needed.

Advantages

The extendable design allows fine length adjustment on-site, reducing the need for cutting or custom shortening of pipes. A mechanical coupling ensures a stable connection without adhesives, and compatibility with standard 5/4" plastic piping simplifies selection for common drainage and waste installations. The connector's straightforward geometry aids rapid fitting and service access when needed.

Suitable for

• Household sink and basin drainage connections
• Toilet and soil pipe attachments in light commercial settings
• Waste and soil system repairs where small length adjustments are required
• Temporary plumbing assemblies and renovation work

Key specifications

• Nominal diameter: 5/4"
• Extendable length: adjustable (allows axial adjustment during installation)
• Intended use: drainage, waste and soil systems
• Material compatibility: common plastic plumbing pipes and fittings
• Connection type: mechanical extendable coupling

How to use

Measure the required insertion depth and align the connector with the mating pipe or fitting. Slide the connector over the pipe ends and extend or retract the adjustable section until the correct length and alignment are achieved. Secure the mechanical joint according to the pipe system practice in use (push-fit, clamp or screw collar if applicable) and verify that the connection is stable and properly sealed for drainage applications. Avoid excessive force when extending to prevent damage to the connector or connected pipes.

Usage recommendations

Use the connector for non-pressurized drainage and waste lines only. Verify compatibility with the specific pipe material and local plumbing codes before installation. For long-term installations in commercial or heavy-duty systems, consider products specified for higher loads or consult a plumbing professional to confirm suitability.
