Insert 1" x 1"

Product detailed description

Insert fittings are essential in heating and plumbing installations where direct connections between threaded pipe ends are required. This model is commonly used in residential and commercial buildings for central heating circuits, domestic hot water systems and underfloor heating manifolds. Installers working with copper or steel pipes can use this fitting to create leak-tight joints within systems operating at moderate temperatures and pressures.

The fitting is designed for applications involving circulating water, where thermal expansion and vibration are present. It supports both rigid and flexible piping layouts and is compatible with standard pipe alignment tools and sealing compounds. When installed correctly, the fitting maintains system integrity and minimises the risk of micro-leaks over time.

Technical parameters

Material	Brass CW617N ATEST for potable water
Operating temperature	+120 °C
Nominal pressure	PN 10
Weight	0.078 kg
Code	1552G000606
Brand	IVAR

The maximum operating temperature of +120°C allows this fitting to be used in hot water circuits and radiant heating systems. The PN 10 rating indicates suitability for low-pressure applications such as domestic water supply and heating distribution. These parameters are critical for ensuring compatibility with the rest of the system and avoiding material degradation or joint failure.

Installation and connection

To install the fitting, first clean the internal threads of the connected pipe ends using a deburring tool. Apply a thin layer of approved pipe thread sealant to the male threads following the manufacturer’s recommendations. Ensure the fitting is fully seated against the shoulder of the pipe end to avoid misalignment. Check the parallelism of the connected pipes before tightening the nuts evenly using a spanner. Common errors include insufficient thread engagement, overtightening which may damage the sealing surface, or failing to remove burrs from cut pipe ends.

Compatibility and accessories

This insert fitting is intended for use with standard 1 inch threaded pipes made of copper, steel or plastic. For systems requiring isolation valves or pressure regulation, additional components such as gate valves or thermostatic mixing valves may need to be specified. Accessories like pipe alignment jigs and thread cutting tools are often used during installation to ensure precision and repeatability.

Technical background for designers

As a solid brass insert, the fitting relies on mechanical compression rather than welding or soldering to create a joint. The CW617N alloy provides good corrosion resistance in water-based systems and retains strength at elevated temperatures. Its smooth internal geometry helps reduce flow turbulence and pressure drop compared to more complex fittings. System designers should consider the cumulative effect of multiple joints on overall hydraulic performance and ensure that all components meet the same pressure and temperature ratings.

Service and operation

During routine inspections, verify the tightness of the joint by checking for signs of leakage around the nut and body interface. Avoid using excessive force when adjusting nuts after initial tightening. In case of suspected leakage, the entire joint should be disassembled and resealed with fresh compound. No scheduled service intervals are specified for this component, provided it remains undamaged and properly sealed.

Frequently asked questions

Can this fitting be used in closed-loop radiant heating systems?
Yes, the operating temperature limit of +120°C makes it suitable for most radiant floor heating circuits.

Is the CW617N material compatible with chlorinated water?
Brass CW617N is resistant to mild chlorination levels typically found in municipal water supplies.

What sealing method should be used with this insert?
A pipe thread sealing compound is recommended to ensure leak-free connections.

Does the PN 10 rating apply to both hot and cold water?
Yes, the pressure rating is valid for all media up to the maximum operating temperature specified.
