Drainage coupling 72-100

Product detailed description

Drainage couplings are essential components in the construction and maintenance of drainage and sewer systems. They are used to connect sections of flexible drainage hose, ensuring a secure and watertight connection. This is particularly important in applications such as surface water drainage, subsurface drainage, and rainwater collection systems. Installers working on residential, commercial, or industrial properties may encounter the need to join flexible drainage hose in a range of diameters. The Karmat PR_38106 is designed to accommodate hose diameters from 72 to 100mm, making it a versatile solution for a variety of drainage configurations.

The coupling is typically used in underground drainage systems where flexible hose is laid in trenches and connected to other components such as inspection chambers, manholes, or drainage outlets. It is also suitable for use in surface drainage applications, such as connecting downpipes to underground drainage lines. The coupling ensures a stable and leak-free connection, which is critical for the long-term performance of the drainage system.

Technical parameters

Code	PR_38106
Brand	Karmat

The coupling is designed for hose diameters between 72 and 100mm. This range allows it to be used with a variety of flexible drainage hose sizes commonly found in drainage systems. The size range is important for ensuring compatibility with different hose types and for accommodating minor dimensional variations in manufactured hose. The coupling is manufactured to provide a secure fit within this range without requiring additional sealing materials.

Installation and connection

Installation of the Karmat PR_38106 involves inserting the ends of the drainage hose into the coupling and securing them in place. The coupling is designed for push-fit installation, which eliminates the need for additional tools or sealing compounds. Prior to installation, the hose ends should be inspected for damage or deformation that could affect the connection. The hose should be cut cleanly and squarely to ensure a proper fit. A common mistake during installation is failing to fully insert the hose into the coupling, which can result in a loose or insecure connection. Installers should ensure that the hose is inserted to the full depth of the coupling and that there is no visible gap between the hose and the coupling body.

Compatibility and accessories

The coupling is compatible with flexible drainage hose in the specified diameter range. It is intended for use with standard drainage hose made of polyethylene or similar materials. For a complete drainage system, additional components such as inspection chambers, manhole covers, and drainage outlets may be required. These components are typically selected based on the specific requirements of the drainage system and the local building codes.

Technical background for designers

The coupling operates on a push-fit principle, where the hose is inserted into the coupling and held in place by friction. The material used for the coupling is a rigid plastic that provides structural integrity and resistance to environmental factors such as moisture and UV exposure. The coupling is designed to integrate into a drainage system by providing a secure connection between hose sections. The service life and efficiency of the coupling depend on the quality of the hose material, the accuracy of the installation, and the absence of mechanical stress on the connection. Proper alignment of the hose and coupling is essential to prevent leakage and ensure long-term performance.

Service and operation

Once installed, the coupling requires minimal maintenance. It is important to periodically inspect the connection for signs of wear, damage, or leakage. If any issues are detected, the affected section of the hose should be replaced and the coupling reinstalled. There are no specific service intervals for this component, as it is designed for long-term use under normal operating conditions. In the event of a blockage or clog in the drainage system, the coupling should be inspected to ensure that it is not the source of the problem.

Frequently asked questions

Can the coupling be used with rigid drainage pipe?
No, the coupling is specifically designed for use with flexible drainage hose and is not suitable for rigid pipe connections.

Is it possible to use the coupling with hose diameters outside the specified range?
No, the coupling is only suitable for hose diameters between 72 and 100mm. Using it with other sizes may result in an insecure or leak-prone connection.

Does the coupling require any sealing compound or adhesive?
No, the coupling is designed for push-fit installation and does not require additional sealing materials.

Can the coupling be used in both horizontal and vertical drainage systems?
Yes, the coupling is suitable for use in both horizontal and vertical drainage configurations, provided that the hose is properly supported and aligned.
