Connector SiGMA-Li ZZ4054 GZ 40x5/4" — pipe fitting adapter

SiGMA-Li ZZ4054 GZ 40x5/4" — pipe fitting adapter is a threaded connector engineered to join a 40x5 pipe to a 1" (5/4") threaded fitting. The component provides a secure mechanical transition between metric pipe dimensions and imperial threaded connections, making it suitable for plumbing systems where different standards meet. Constructed for standard domestic and light commercial plumbing applications, this connector facilitates reliable coupling to valves, fixtures, and other threaded components.

Advantages

The adapter offers a precise threaded interface that reduces the need for custom machining or improvised joins. Its design supports straightforward installation and a compact footprint, which helps conserve space in tight plumbing layouts. By providing a direct transition between a 40x5 pipe and a 1" threaded connection, the connector minimizes leak points when used with appropriate sealing materials and installation practices.

Suitable for

• Connecting 40x5 pipes to 1" (5/4") threaded valves and fittings
• Domestic water supply and distribution systems
• Light commercial plumbing installations
• Repair and retrofit jobs where metric-to-imperial transition is required

Key specifications

• Connection type: threaded pipe-to-thread adapter
• Piping dimension (pipe side): 40x5 mm
• Threaded side: 1" (5/4") male thread
• Application: plumbing and fluid systems
• Installation orientation: inline mechanical connector

How to use

Prepare the pipe end by cutting square and deburring the 40x5 pipe to ensure a clean fit. Apply an appropriate thread sealant or tape to the 1" threaded side if required by the installation standards and the materials being joined. Hand-start the male thread into the mating fitting, then tighten with the correct tools until a secure mechanical seal is achieved. Verify alignment and check for leaks under pressure before completing the installation.

Usage recommendations

Use compatible sealing materials and follow local plumbing codes. Inspect mating threads for damage and ensure pipe wall integrity is suitable for mechanical threading transitions. For systems carrying potable water, confirm material compatibility and any regulatory requirements prior to installation.
