## Summary description

Unidelta transition fitting made of PE with a female 1" threaded connection and 40 mm socket end. Designed to join polyethylene pipe to a 1" threaded metal or plastic fitting, it provides a secure mechanical and leak-resistant connection for water supply, irrigation and plumbing systems. Suitable for installation in household and light commercial piping.

## Long description

Unidelta transition fitting PE female threaded 40 mm x 1" is a polyethylene connector designed to join 40 mm PE pipe to a 1" female threaded metal or plastic fitting. The part combines a smooth socket for PE pipe insertion with a 1" internal thread to accept standard male threads, providing a mechanically secure and leak-resistant junction for water supply, irrigation and light plumbing installations. Constructed for compatibility with common PE piping and threaded components, this transition fitting is suitable for both household and light commercial use where a reliable interface between flexible polyethylene piping and threaded fixtures is required.
Advantages
The Unidelta PE transition fitting offers corrosion resistance inherent to polyethylene, reduced risk of electrochemical reactions when connecting to metal fittings, and a lightweight design that simplifies handling and installation. Its integral socket and threaded section provide consistent alignment and clamping of the PE pipe, while the internal thread gives a standardized connection to 1" male fittings. The material choice and construction reduce maintenance needs and provide durable performance in potable water, irrigation and non-aggressive fluid systems.
Suitable for
Connecting 40 mm polyethylene (PE) pipe to 1" male threaded valves, taps or adapters
Domestic water supply and garden irrigation systems
Light commercial plumbing where PE piping interfaces with threaded components
Temporary or permanent installations requiring a mechanically secure, leak-resistant transition
Key specifications
Material: polyethylene (PE)
PE connection: 40 mm socket for insertion and mechanical fastening
Threaded connection: internal 1" (female) standard thread for male fittings
Function: transition fitting for joining PE pipe to threaded fittings
Application fluids: potable water, irrigation water, non-aggressive liquids
How to use
Prepare the 40 mm PE pipe by cutting it squarely and deburring the end. Ensure the pipe exterior is clean and free of contaminants. Insert the PE pipe into the socket end of the transition fitting to the recommended insertion depth, then secure it according to the connection method appropriate for the specific Unidelta fitting (mechanical clamp, compression or heat fusion as applicable). Thread the male 1" fitting into the internal female thread by hand to engage threads, then tighten with an appropriate wrench to ensure a leak-resistant seal without over-torquing. Verify alignment and perform a pressure test in accordance with local plumbing standards before placing the system into regular use.
Usage recommendations
Use compatible 1" male fittings and ensure the PE pipe is rated for the system pressure and fluid type. Avoid exposing the fitting to aggressive chemicals or temperatures beyond the PE material limits. When installing in buried or UV-exposed locations, follow best practices for protection and support of PE piping to prevent stress at the transition.
