Transition elbow 90° PRESS GAS - internally threaded - 35mm-Rp5/4" IVAR.IVN30 GAS

Product detailed description

This transition elbow is commonly used in residential and commercial gas supply systems. It allows the connection between press-fitted stainless steel pipe and threaded components in gas distribution lines. Installers working on gas networks for natural gas, biogas or liquid propane will find this fitting suitable for branch connections and directional changes in the pipeline. The elbow is dimensioned for nominal pressures up to PN 5 and operates within a temperature range from -20 °C to +70 °C.

Its compact design and precision-machined internal thread make it ideal for tight spaces and for maintaining alignment during installation. The sealing mechanism ensures a leak-free connection under normal operating conditions. This elbow is typically used in conjunction with other press fittings and valves in gas supply lines for kitchens, boiler rooms, and industrial gas applications.

Technical parameters

Installation and connection

The transition elbow connects press-fitted stainless steel pipe to a threaded component. The internal thread (Rp 5/4") must align with the corresponding external thread of the connected part. During installation, ensure the sealing O-ring is undamaged and seated correctly in the groove. Use a torque wrench to tighten the connection according to manufacturer specifications. Avoid over-tightening, which can damage the O-ring or distort the fitting. Check the alignment of the pipe and elbow to prevent stress on the joint.

Common installation errors include using incorrect thread types or applying excessive force when tightening. Always verify the integrity of the press connection before installing the elbow. After assembly, perform a leak test using approved methods such as soap solution or gas detectors.

Compatibility and accessories

This elbow is compatible with IVAR stainless steel press pipes and fittings of the same material and nominal diameter. When installing, ensure that all components are from the same system to maintain compatibility and sealing performance. Additional components such as valves, regulators and pressure-reducing devices may be required depending on the system configuration. No specific related products are listed for this model.

Technical background for designers

The elbow functions as a directional change in gas pipelines, allowing the system to follow structural constraints. The use of stainless steel 1.4404 provides resistance to corrosion and mechanical wear, making it suitable for long-term exposure to gaseous fuels. The HNBR sealing ring ensures flexibility and durability under varying temperatures and pressures. Integration into the system should account for thermal expansion and contraction of the piping material. The longevity and efficiency of the elbow depend on correct installation, proper alignment, and the absence of mechanical stress at the joint.

Service and operation

During operation, the elbow requires no active maintenance. However, periodic visual inspections are recommended to check for signs of mechanical damage or corrosion. Ensure the sealing ring remains intact and free from contaminants. If a leak is suspected, isolate the system and perform a leak test before attempting any repairs. No scheduled service intervals are specified for this component.
