Accessories for HT

Product detailed description

HT waste pipe systems are commonly used in residential and commercial buildings for drainage and sanitation applications. Installers working with these systems often encounter push-fit connections that require lubrication and solvent-weld joints that need precise application of cement. This product kit provides the essential consumables required for sealing and assembling plastic waste pipes in HT systems. The lubricant is specifically designed for hinged HT connections that do not require adhesive, while the two cements are for use with different types of plastic piping materials.

Proper preparation and application of these materials is critical for ensuring watertight and durable connections. The lubricant reduces friction during assembly, while the cements chemically fuse pipe and fitting surfaces. The NOVODUR-specific cement is formulated for PVC components, ensuring long-term stability in waste pipe networks. This product is intended for use by professional installers working with HT and NOVODUR systems in new builds and renovation projects.

Technical parameters

Weight	0.2 kg
Code	LEPIDLOHT125
Brand	HPW®

The product includes three components with specific volumes: 150 ml lubricant, 125 ml general-purpose cement, and 130 ml NOVODUR-specific cement. These quantities are sufficient for multiple joints in a typical installation. The lubricant is used exclusively with hinged HT connections, while the cements are selected based on the material of the components being joined. The weight of the complete set is 0.2 kg, making it suitable for transport and storage in a tool kit.

Installation and connection

The lubricant should be applied to sealing rings and pipe ends to facilitate smooth assembly and prevent the rings from being displaced during installation. For solvent-weld joints, surfaces must be clean, dry, and free of grease. Apply a thin, even layer of cement with a brush, then join the components in a single smooth motion. Allow the joint to cure according to the instructions on the container. Common installation errors include over-application of cement, improper alignment of components, and failure to clean surfaces before application. Always ensure the correct cement is used for the material being joined.

Compatibility and accessories

This product is specifically designed for use with HT push-fit waste pipe systems and NOVODUR PVC components. It is not compatible with other types of piping materials or systems that require different adhesives or assembly methods. No additional accessories are required for basic installation, but installers should ensure they have the appropriate tools for cutting and preparing pipe ends. The product is intended for use with the full range of HT fittings and NOVODUR PVC pipes and fittings.

Technical background for designers

The lubricant reduces friction during assembly of hinged HT connections, ensuring that sealing rings remain in place and do not get compressed unevenly. The general-purpose cement is a solvent-based adhesive that chemically fuses the surfaces of plastic components, creating a permanent bond. The NOVODUR-specific cement is formulated for PVC, ensuring compatibility and long-term stability in waste pipe systems. The materials used are designed to withstand the mechanical and chemical stresses of waste flow, including abrasion and exposure to mild detergents. The choice of cement affects the durability and integrity of the system, particularly in high-flow or high-load applications.

Service and operation

No regular maintenance is required for joints made with these materials. However, during installation, it is important to check that surfaces are properly cleaned and that the correct cement is used for the material being joined. If a joint fails, it should be disassembled and reassembled with fresh cement. The curing time should be respected to ensure full bonding strength. No service intervals are specified for these materials, as they are designed for long-term use in waste pipe systems.

Frequently asked questions

Can the lubricant be used with all HT connections?
The lubricant is suitable only for hinged HT connections that do not require adhesive. It should not be used with solvent-weld joints.

Is the general-purpose cement suitable for NOVODUR PVC?
No, the general-purpose cement is not recommended for NOVODUR PVC components. A separate NOVODUR-specific cement is included in the set for this purpose.

How long should the cement be allowed to cure?
Curing time depends on the ambient temperature and humidity. Refer to the instructions on the container for specific guidance.

Can the cement be used for repairs?
Yes, the cement can be used for repairing failed joints. Ensure the surfaces are clean and dry before reapplication.
