KAN-therm fitting with internal thread 90 x 3" PP – model 04103190

The KAN-therm fitting with internal thread 90 x 3" PP – model 04103190 is a polypropylene connection element designed to create a threaded outlet on PP piping systems. It provides a corrosion-resistant junction between polypropylene pipes and components that require a 3" internal thread. The fitting is intended for use in plumbing and heating installations where a durable, chemical-resistant plastic threaded connection is preferred.

Advantages

This polypropylene fitting offers chemical and corrosion resistance typical of PP materials, resulting in long-term stability in contact with water and common heating fluids. Its molded internal thread ensures compatibility with standard threaded components while maintaining a lightweight and non-conductive joint. The design reduces the need for metal adapters and minimizes the risk of galvanic corrosion where dissimilar materials would otherwise meet.

Suitable for

• Creating a 3" threaded outlet on polypropylene pipe runs in residential plumbing systems
• Integrating threaded valves or access points into heating distribution networks
• Connections where chemical resistance and non-metallic joints are preferred
• Light commercial installations with PP piping requiring a threaded interface

Key specifications

• Material: polypropylene (PP)
• Connection type: internal (female) thread
• Thread size: 3"
• Pipe outer diameter compatibility: 90 mm
• Application: plumbing and heating systems
• Properties: corrosion-resistant, non-conductive, lightweight

How to use

Prepare the polypropylene pipe end by cutting squarely and deburring to ensure a clean surface. Fit the PP fitting onto the pipe according to the manufacturer's recommended joining method for KAN-therm PP components (typically fusion welding or compatible mechanical jointing as specified for the system). Thread the mating component into the internal 3" thread by hand to start, then tighten to the required torque using suitable tools and sealing method if needed. Follow standard plumbing practice to verify alignment and leak-tightness after installation.

Usage recommendations

Use this fitting within the temperature and pressure limits specified for KAN-therm PP piping systems. Avoid exposure to open flames and excessive localized heating during installation. For reliable performance, employ qualified personnel familiar with polypropylene joining techniques and confirm compatibility with threaded metal components to prevent mechanical stress and ensure a secure, leak-free connection.
