Extension - long, 60 x 1"

Product detailed description

Long extensions are commonly used in heating and plumbing systems where additional length is required between threaded connections. These fittings are essential in applications such as central heating installations, underfloor heating circuits, and domestic water supply lines. They allow for precise alignment and secure coupling of components while maintaining system integrity. Installers working in residential, commercial and industrial settings often rely on these fittings to adapt to varying pipe layouts and spacing constraints.

In systems where rigid alignment is not possible due to structural limitations, long extensions provide flexibility. They are frequently used in conjunction with valves, meters and manifolds to extend reach without compromising pressure ratings or sealing performance. Their design supports both horizontal and vertical installations and can be integrated into systems requiring frequent disassembly for inspection or maintenance.

Technical parameters

Installation and connection

This extension features a 1 inch male thread on both ends. Prior to installation, ensure that the mating threads are clean and undamaged. Apply a suitable thread sealant or PTFE tape to prevent leaks. Align the extension carefully to avoid cross-threading during tightening. Tighten using a wrench or spanner until the joint is secure, but avoid over-tightening which can damage the threads or seating surfaces.

Compatibility and accessories

This extension is compatible with standard 1 inch threaded fittings and valves. When extending pipe runs or connecting to components such as ball valves or pressure regulators, ensure all parts have matching thread sizes and types. Additional items such as unions or couplings may be needed for complex connections or where disassembly is required. For potable water systems, confirm that all connected components also meet relevant water safety standards.

Technical background for designers

The extension functions as a passive component that transfers fluid or heat between two threaded connections. The CW617N brass alloy provides good mechanical strength and resistance to both internal and external corrosion, ensuring long-term reliability. Its PN 10 rating allows it to handle typical pressures in domestic and light industrial systems. The operating temperature limit of +120°C makes it suitable for hot water and heating applications. System efficiency is maintained through minimal flow restriction and tight sealing, provided the installation is correct and the mating components are of equal quality.

Service and operation

During regular system checks, inspect the extension for signs of corrosion, thread wear or leakage. Any damage or deformation should prompt replacement to maintain system integrity. No specific service intervals are required for this component unless indicated by system performance issues. In potable water systems, ensure ongoing compliance with water safety regulations by replacing worn or damaged fittings.

Frequently asked questions

Can this extension be used in drinking water systems?
Yes, it is certified for potable water use with the CW617N material and ATEST approval.

Is it compatible with other 1 inch threaded fittings?
Yes, provided they have the same thread type and are suitable for the intended pressure and temperature conditions.

What is the maximum operating temperature?
It can be used in systems with an operating temperature of up to +120°C.

Can it be used in heating systems?
Yes, the PN 10 rating and temperature capability make it suitable for use in heating circuits and hot water systems.
