Sprinkler Loop ZPF M10 1½ (48–50 mm) Niczuk

The Niczuk Sprinkler Loop ZPF M10 1½ (48–50 mm) is a connection assembly intended for use in wet and dry sprinkler systems requiring a 48–50 mm nominal loop interface. Designed with a threaded M10 1½ connection, the loop provides a fixed routing and mounting point for sprinkler heads and branch piping. The product is intended to integrate with standard sprinkler risers and piping arrangements where a compact loop fitting is required to position or orient sprinkler heads consistently.

Advantages

The sprinkler loop offers a robust threaded connection that simplifies installation and ensures a secure mechanical joint between the branch piping and sprinkler head assemblies. Its design suits both new installations and retrofit projects, providing a consistent mounting geometry to reduce alignment adjustments during commissioning. Manufactured to meet typical fire protection component expectations, the loop contributes to reliable water delivery and stable sprinkler positioning.

Suitable for

• Commercial and residential wet sprinkler systems
• Dry-pipe sprinkler installations where a 48–50 mm loop connection is specified
• Branch piping runs requiring a compact loop fitting for sprinkler head orientation
• Retrofit and upgrade projects to replace or standardize sprinkler loops

Key specifications

• Connection type: threaded M10 1½
• Nominal loop diameter compatibility: 48–50 mm
• Function: loop fitting for sprinkler head mounting and piping routing
• Application environment: designed for use in fire sprinkler systems (wet and dry configurations)
• Material: corrosion-resistant metal suitable for plumbing and fire protection use

How to use

Install the Sprinkler Loop ZPF M10 1½ in the branch line at the designated sprinkler location following applicable fire protection design drawings and local regulations. Ensure threads are clean and undamaged before assembly. Apply appropriate thread sealing method or gasket as specified by system design and compatibility with the piping materials. Tighten to the torque values recommended for the piping system fittings to secure the connection without deforming threads. After installation, align the sprinkler head and verify orientation, then perform standard pressure tests and commissioning checks according to fire protection standards.

Usage recommendations

Use the loop only in systems designed for a 48–50 mm nominal connection and ensure compatibility with the sprinkler head and piping materials. Follow local codes and manufacturer guidelines for sealing, torque, and testing. For installations in corrosive environments, select compatible materials and protective measures to maintain long-term performance.
