Elbow fitting THERMAFLEX Kolano PE 35/9 model 3526-009035-030 for PE piping systems

THERMAFLEX Kolano PE 35/9 model 3526-009035-030 is an elbow fitting for polyethylene (PE) piping systems designed to provide a compact directional change in plumbing and fluid transport installations. The product is intended to connect PE pipes of the designated dimensions and to redirect flow with a consistent internal profile that preserves hydraulic performance.

Advantages

The THERMAFLEX PE elbow offers a compact footprint and a smooth internal curvature that reduces turbulence and pressure loss compared with abrupt-angle joins. Its construction is suitable for typical water and low-pressure fluid distribution systems made from polyethylene, delivering durable connections with good resistance to corrosion and many chemicals compatible with PE. The fitting is manufactured to fit specified PE pipe dimensions, allowing straightforward integration into existing polyethylene piping layouts.

Suitable for

• Domestic and commercial cold-water distribution using PE piping
• Irrigation and landscape water supply networks
• Routing fluid lines in tight spaces where a compact 35/9 elbow is required
• Retrofit or new installations with compatible polyethylene pipes

When it may not be suitable

This elbow is intended for polyethylene piping and may not be appropriate for systems using materials other than PE unless proper transition fittings are employed. It is designed for typical low- to medium-pressure fluid transport; high-pressure, high-temperature, or aggressive chemical services beyond PE material limits require alternative fittings rated for those conditions.

Key specifications

• Material: polyethylene-compatible fitting intended for PE pipe systems
• Type: elbow for changing pipe direction
• Angle/size designation: 35/9 configuration for compact directional change
• Application: plumbing and fluid transport in PE networks

How to use

Install the elbow by preparing the ends of the polyethylene pipes according to good practice: cut square, clean, and deburr pipe ends. Use compatible joining methods for PE systems (for example butt fusion, electrofusion, or the specified mechanical connection compatible with the fitting) following manufacturer instructions and applicable standards. Ensure proper alignment and allow recommended cool-down or curing time for welded joints before pressurising the system. Test the assembled piping at recommended test pressures and inspect connections for leaks prior to commissioning.

What to consider before purchase

• Verify compatibility with the specific PE pipe dimension and joining method used in your project.
• Confirm the pressure and temperature range of your system matches PE material limits.
• Check whether transition fittings are needed for connection to non-PE components.

Usage recommendations

Follow industry best practices for PE pipe preparation and fusion or mechanical joining. Store the fitting in a clean, dry environment and avoid exposure to direct UV for extended periods prior to installation. Conduct pressure testing after installation and adhere to local codes and manufacturer guidelines for safe operation.
