## Summary description

SiGMA-Li compression fitting model GZ. - 25x3/4 is designed for use with PE-RT pipes. The fitting matches a 25 mm pipe to a 3/4" threaded connection and is intended for reliable pipe-to-thread joints in heating and plumbing systems. Suitable for installations requiring a PE-RT to threaded transition and standard mechanical sealing.

## Long description

SiGMA-Li compression fitting GZ. - 25x3/4 for PE-RT pipe is a mechanical transition component designed to join 25 mm PE-RT tubing to a 3/4" threaded connection. The fitting provides a compact solution for creating a secure pipe-to-thread joint in heating and plumbing installations where a reliable mechanical seal is required. Its design supports standard installation procedures for PE-RT systems and enables connection to valves, manifolds or other threaded components.
Advantages
The fitting offers a straightforward compression connection without the need for additional adhesives or heat-based joining methods, reducing installation time. Constructed to match PE-RT pipe dimensions, it maintains flow integrity and minimizes the risk of leaks when installed correctly. The 3/4" threaded outlet allows compatibility with common plumbing fixtures and fittings, facilitating integration into existing systems.
Suitable for
Connecting 25 mm PE-RT pipes to 3/4" threaded valves and components
Hot water circulation and underfloor heating manifolds using PE-RT tubing
Service or repair operations requiring a mechanical pipe-to-thread transition
Key specifications
Pipe compatibility: PE-RT, 25 mm nominal diameter
Thread connection: 3/4" male/female threaded interface for standard plumbing components
Connection type: compression fitting designed for mechanical sealing
Application area: heating and plumbing systems requiring pipe-to-thread transition
How to use
Prepare the PE-RT pipe by cutting it squarely and removing any burrs or debris. Slide the compression nut and ferrule onto the pipe, insert the pipe end fully into the fitting body until it seats, then tighten the compression nut to the manufacturer-recommended torque to form the seal. Thread the 3/4" connection to the mating component using appropriate sealing methods for threaded joints if needed, such as PTFE tape or a suitable sealant, following standard plumbing practice.
Usage recommendations
Verify pipe compatibility and dimensions before installation, use proper tools to ensure square cuts and correct torque on the compression nut, and pressure-test the system after assembly to confirm leak-free operation. Avoid overtightening threaded connections to prevent damage to sealing surfaces.
