## Summary description

Pipe elbow fitting Alkotest K4525 with a 45° angle and 25 mm (FI25) diameter, made of polypropylene. Designed to change the direction of piping runs in plumbing and heating systems. Suitable for connecting compatible 25 mm polypropylene pipes and fittings, offering corrosion-resistant, lightweight joint for water distribution and low-pressure systems.

## Long description

Alkotest K4525 elbow 45° pipe fitting, 25 mm (FI25) polypropylene is a molded 45-degree elbow designed for use with 25 mm polypropylene piping systems. It provides a smooth directional change in plumbing and heating installations and is suitable for cold and warm water distribution and other low-pressure applications. The fitting's polypropylene construction delivers resistance to corrosion and chemical attack while remaining lightweight and easy to handle during installation.
Advantages
The polypropylene construction combines chemical resistance with low thermal conductivity, reducing the risk of corrosion and scale formation compared with metal fittings. The 45° angle enables gentler flow redirection than a 90° elbow, which can reduce flow turbulence and pressure loss. Its standardized 25 mm connection dimensions allow compatibility with matching polypropylene pipes and fittings for secure, leak-resistant joints when assembled following recommended joining methods.
Suitable for
Domestic cold and hot water distribution in low-pressure systems
Heating circuits and underfloor heating manifolds compatible with polypropylene piping
Pipe routing in potable water installations where corrosion resistance is required
Light industrial applications with non-aggressive fluids and low pressures
Key specifications
Material: polypropylene (PP) for corrosion resistance and low weight
Angle: 45° elbow for gradual change of pipe direction
Nominal diameter: 25 mm suitable for FI25 polypropylene pipes
Connection type: slip/socket designed for compatible polypropylene pipes and fittings
Application pressure: intended for low-pressure water distribution systems (follow system design limits)
How to use
Prepare pipe ends by cutting squarely and deburring to ensure full insertion into the elbow socket. Clean mating surfaces and, where applicable, apply the recommended joining method for polypropylene systems (such as appropriate solvent cement or thermal fusion process) following manufacturer and local plumbing codes. Insert the pipe fully into the socket and allow the joint to cure or cool as required before pressurizing the system. Verify alignment and support pipes to avoid undue stress at the joint.
Usage recommendations
Confirm compatibility of the elbow with the chosen joining method and the specific grade of polypropylene pipe. Avoid installation in systems exceeding the designed temperature and pressure limits for polypropylene components, and secure adequate mechanical support and expansion allowances in long runs.
