Flat gasket coupling IVAR.IVN460 28 mm – G 5/4", crimped, stainless steel AISI 304 / brass

Product detailed description

Connecting sleeve IVAR.IVN460 28 mm – G 5/4" is used for transition from pressed stainless steel pipe to heating fittings or components with external thread G 5/4". The pressing end for the 28 mm tube is sealed with an EPDM O-ring, while the opposite side features a union nut that is screwed onto the mating part and tightened using a flat gasket. The sleeve combines stainless steel AISI 304 (1.4301) with brass. The overall length is 44 mm, with a dimension Z according to the drawing of 10 mm.

Where it is used

• closed heating and cooling circuits, solar systems
• compressed air, vacuum systems, inert and technical gases
• technical and operational liquids, industrial applications
• sewage and rainwater

The sleeve is not suitable for potable water. It withstands an operating pressure up to PN 16, a vacuum down to -0.8 bar (absolute pressure 0.2 bar), a temperature range from -20 °C to +85 °C with a maximum of +120 °C, and antifreeze mixtures with a concentration of up to 50 %.

Pressing and connection inspection

Cut the 28 mm tube perpendicularly, deburr the inside and outside, and insert it fully until it reaches the stop; press using jaws with contour M. The patented LBP (Leak Before Press) O-ring has a segmented profile, so an improperly pressed joint will show a liquid leak during pressure testing, and the orange stripe indicates successful pressing. Installation should be entrusted to a qualified professional who follows the manufacturer's instructions; before starting the heating system, the manufacturer recommends flushing the system and treating the water with the preparation GEL.LONG LIFE 100.

The IVAR.IVN460 range includes sleeves for tubes from 15 to 54 mm with threads from G 1/2" to G 2".

Technical specifications

Frequently asked questions

Which mating part is suitable for the IVAR.IVN460 28 mm – G 5/4" sleeve?
The union nut with G 5/4" thread is screwed onto a fitting or component with an external thread of the same size; the connection is sealed with a flat gasket. The other end is pressed onto a stainless steel tube of 28 mm.

Can the sleeve be used for potable water?
No. It is intended for closed heating and cooling systems, solar circuits, compressed air, technical gases and liquids, or sewage and rainwater.

How is the pressing end installed?
Cut the tube perpendicularly, deburr the inside and outside, and insert it fully until it reaches the stop, then press using jaws with contour M. The LBP O-ring and orange stripe will help detect an improperly pressed joint.

What temperatures and pressure can the sleeve withstand?
Operating pressure up to PN 16 and temperature from -20 °C to +85 °C, with a maximum of +120 °C. The antifreeze mixture may have a concentration of up to 50 %.
