VIEGA Viega 1115.1 steel reducer coupling, diameter 22 mm, pack of 10

VIEGA Viega 1115.1 steel reducer coupling, diameter 22 mm, pack of 10 is a galvanised non‑alloyed steel reducer coupling designed for Prestabo‑style mechanical connections. It is intended for joining pipes where a reduction in diameter is required and is supplied in packs of ten units. The coupling features a plug‑in end and press connection with an EPDM sealing element and is manufactured with the withSC‑Contur safety contour to support reliable installation and leak detection during pressure tests.

Advantages

The coupling is made from galvanised non‑alloyed steel, offering corrosion resistance suitable for plumbing and heating systems. The EPDM sealing element provides a durable elastomeric seal compatible with many media used in heating and potable water applications. The Prestabo‑style plug‑in end and press connection allow for mechanical joining without welding, reducing installation time and enabling secure, repeatable connections. The withSC‑Contur design aids in pressure testing by making unintended unpressed connections visible.

Suitable for

• Reducing pipe diameter in plumbing systems
• Connections in heating system installations
• Repair and retrofit jobs requiring mechanical coupling instead of welding
• Professional installation where press‑fit reliability is required

When it may not be suitable

This reducer coupling is designed for mechanical press and plug‑in connections and is not intended for applications requiring threaded or welded joints. It is supplied with a 22 mm diameter specification and therefore will not fit systems that require different sizes without appropriate adapters or alternative fittings. For corrosive chemical environments or non‑standard media, confirm material compatibility with EPDM and galvanised steel before use.

Key specifications

• Material: galvanised non‑alloyed steel
• Connection type: plug‑in end with press connection
• Sealing: EPDM sealing element
• Design feature: withSC‑Contur
• Diameter (reduced end): 22 mm
• Packaging: pack of 10 units

How to use

Prepare pipe ends by cutting square and removing burrs and debris. Insert the pipe into the plug‑in end to the required stop and position the coupling in the press tool according to tool and jaw manufacturer instructions. Perform the press operation to create the mechanical joint. Verify the press was completed correctly by visual inspection and pressure testing as part of the commissioning process; the withSC‑Contur feature assists in identifying areas that were not pressed. Follow local plumbing and heating installation standards and the press tool manufacturer’s guidelines for safe, leak‑free joints.

What to consider before purchase

• Confirm system pipe diameters and that a 22 mm reduced end is suitable.
• Ensure press‑fit installation tools and compatible press jaws are available.
• Check EPDM and galvanised steel compatibility with the transported medium.
• Verify that a pack of 10 units matches project quantity and spare parts needs.

Usage recommendations

Use certified press tools and follow manufacturer instructions; perform pressure tests after installation to confirm integrity. Store couplings in a dry environment to preserve galvanised coating and inspect EPDM seals before use.
