VIEGA Viega 4217.2 steel disk Ø20 cm pack of 5

VIEGA Viega 4217.2 steel disk Ø20 cm pack of 5 is a set of five identical circular steel components with a nominal diameter of 20 cm designed for plumbing and installation applications. Each disk is manufactured from non-alloyed steel with a protective zinc-nickel coating and is intended for use in systems based on steel pipe standards. The pack provides multiple parts for series installations, repairs or projects that require robust metal fittings and uniform components.

Advantages

The disks combine the mechanical strength of non-alloyed steel with a corrosion-resistant zinc-nickel surface treatment, offering long service life in compatible environments. Designed to work with press connections and Rp-threads, they integrate with common installation techniques. Included EPDM sealing elements, cutting rings and separator rings facilitate reliable joints and help maintain tightness under normal operating conditions.

Suitable for

• Plumbing and pipework installations using steel pipes to EN10220/EN10255 standards
• Repair and replacement tasks requiring multiple identical metal disks
• Pre-assembly and prefabrication of pipe systems with press connections or Rp-threaded interfaces

Key specifications

• Quantity: pack of 5 disks
• Diameter: 20 cm (Ø20 cm)
• Material: non-alloyed steel
• Surface finish: zinc-nickel coating for enhanced corrosion resistance
• Compatible connection types: press connections and Rp-thread
• Sealing materials: EPDM sealing elements included
• Additional components: cutting rings and separator rings included

How to use

Select the appropriate disk size and prepare the mating pipe or fitting according to standard installation procedures for steel piping. Ensure sealing elements and cutting rings are positioned correctly on the disk before making the joint. For press connections, follow the press tool manufacturer’s instructions to achieve the correct compression and secure the joint. For Rp-threaded interfaces, apply suitable thread sealant or tape as required and tighten to the specified torque. Inspect each connection after assembly for proper seating and tightness.

Usage recommendations

Store the disks in a dry environment to preserve the zinc-nickel coating. Verify compatibility with the specific steel pipe class (EN10220/EN10255) and operating media. Use only approved tools for press connections and observe recommended torque values for threaded joints to ensure reliable, leak-free installations.
