Compression Fitting SiGMA-Li GZ. - 25x3/4 for PE-RT pipe

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.
