Coupling S-Press with nipple 50 mm (2"), Uponor

Uponor S-Press coupling with nipple 50 mm (2") is a metal press-fit fitting designed for making secure, permanent joints in plumbing and heating installations. The coupling accepts compatible 50 mm (2") pipes and provides a continuous metallic connection using press technology. It is intended for use in potable water systems, heating circuits and other applications where a press connection delivers a fast, reliable seal without soldering or threaded joints.

Advantages

The S-Press coupling with nipple offers a durable metal-to-metal connection that resists pressure and temperature variations common in domestic and commercial heating and potable water systems. Press installation reduces installation time compared with soldering and creates a consistent joint profile. The design is compatible with standard press tools and jaws for the S-Press range, enabling repeatable, leak-resistant connections when installed according to manufacturer guidance.

Suitable for

• Forming press-fit connections between 50 mm (2") copper or compatible metal pipes and fittings
• Domestic and commercial potable water distribution
• Heating circuits, including radiators and central heating manifolds
• Service runs and installation sections where a mechanical press joint is preferred over soldering or welding

When it may not be suitable

This coupling is intended for use with press-fit systems and compatible metal pipes; it is not suitable for plastic pipes that require specific transition fittings or for applications requiring threaded or welded joints. It may not be appropriate where inspection rules or local regulations mandate alternative joining methods or where non-metallic materials are specified.

Key specifications

• Nominal diameter: 50 mm (2")
• Type: Coupling with nipple for press-fit installation
• Material: Metal press fitting suitable for potable water and heating systems
• Connection method: Press-fit (requires compatible press tool and jaws)
• Typical use temperature range: Suitable for domestic hot and cold water and heating circuit temperatures (refer to system design limits)

How to use

Select compatible 50 mm (2") pipes and ensure pipe ends are cut square, deburred and cleaned. Position the coupling with nipple onto the pipe until fully seated. Use the recommended S-Press press tool and appropriate jaw size to make the press connection, following the press tool manufacturer’s instructions. After pressing, verify the joint visually and perform any required pressure testing in accordance with local codes and installation guidelines.

What to consider before purchase

• Confirm compatibility with the pipe material and the press system in use (S-Press).
• Ensure you have the correct 50 mm (2") press tool jaws for a reliable connection.
• Check local plumbing and heating regulations for approved joining methods.

Usage recommendations

For consistent, leak-free results, use certified press tools and replace jaws when worn. Perform pressure testing after installation and follow local codes for potable water and heating systems.
