KAN-therm coupling with internal thread 32 x 1" PP – model 04103132

KAN-therm coupling with internal thread 32 x 1" PP (polypropylene) is a transition fitting designed to connect a 32 mm plastic pipeline to a 1" threaded component. Manufactured from polypropylene, the coupling ensures chemical resistance, low weight and compatibility with standard PP piping systems. It is intended for plumbing and heating installations where a reliable, leak-resistant connection between a PP pipe and a threaded fitting is required.

Advantages

The polypropylene construction offers corrosion resistance and a smooth inner surface that reduces flow resistance and scaling. The integrated internal thread provides a straightforward mechanical connection to standard 1" threaded fittings without the need for additional adapters. The lightweight design simplifies handling during installation and reduces stress on pipe supports. The coupling is dimensioned to match 32 mm PP piping, ensuring stable and concentric connections.

Suitable for

• Connecting 32 mm PP pipes to 1" threaded valves, taps or equipment
• Domestic and commercial plumbing systems
• Heating circuits and low-pressure closed-loop systems
• Retrofitting or repair work where transition from plastic pipe to threaded component is needed

Key specifications

• Material: polypropylene (PP)
• Pipe connection size: 32 mm (for PP pipe)
• Thread type: internal 1" (female) thread for threaded fittings
• Application: potable water, heating and general plumbing where PP piping is used
• Properties: corrosion resistant, lightweight, smooth internal surface

How to use

Prepare the 32 mm PP pipe by cutting a clean, square end and deburring the inner and outer edges. Slide the pipe into the coupling until it seats fully according to the manufacturer's insertion depth guidelines, then complete the joint using the appropriate PP joining method compatible with the coupling (thermal fusion or solvent welding, as applicable for the specific product variant). After securing the pipe side, screw the 1" threaded fitting into the internal thread of the coupling, using appropriate thread sealant or PTFE tape on the male thread to ensure leak-tightness. Tighten to the recommended torque for the mating fitting while avoiding overtightening that could deform plastic components.

Usage recommendations

Verify compatibility of the coupling with the chosen PP pipe system and confirm whether thermal fusion or adhesive joining is required. Use thread sealant suitable for potable water or heating systems on the male thread, and follow installation best practices such as pressure testing after assembly and protecting the joint from excessive mechanical loads and high-temperature excursions beyond the product's rated use.
