Arch 90° - internally threaded, 15 x Rp 1/2

Product detailed description

90° elbows with internal threading are essential in closed pressurised systems such as central heating, fire protection, air conditioning and industrial pipelines. These fittings allow directional changes in piping layouts while maintaining hydraulic integrity. Installers commonly encounter them in residential, commercial and industrial buildings where space constraints require compact bends. The elbow’s dual interface—press-fit on one end and internal thread on the other—facilitates hybrid connections between pre-pressed and threaded components. This makes it suitable for retrofitting or extending existing systems without complete disassembly.

Correct installation ensures long-term performance and leak-free operation. The elbow is often used in conjunction with other press-fit and threaded fittings to create complex networks. It is particularly useful in applications requiring flexibility in alignment and access for future maintenance. The elbow’s lightweight design and ease of handling reduce installation time and effort compared to traditional welded or soldered methods.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.082 kg
Code	IVC82.1512
Brand	IVAR

The elbow operates within a temperature range from -20 °C to +120 °C, which is suitable for most heating and industrial applications. It is rated for nominal pressure PN 16 and can withstand up to 16 bar, making it suitable for high-pressure systems. These parameters are critical for ensuring compatibility with the overall system design and for selecting the correct component in accordance with hydraulic and thermal requirements.

Installation and connection

The elbow is installed using a press tool compatible with Type M jaws. The press-fit side connects directly to a seamless steel pipe, while the internally threaded side accepts a male-threaded pipe or fitting. Ensure the press mark is fully visible after pressing and that the molding indicator is engaged. Check that the EPDM sealing ring is correctly seated in the groove before tightening the threaded connection. Common installation errors include misalignment during pressing, insufficient tightening of threaded joints, and use of incompatible sealing materials. Always follow the manufacturer’s instructions for press depth and torque specifications.

Compatibility and accessories

This elbow is compatible with other IVAR press-fit and threaded components within the IVC82 and IVC83 series. It requires seamless steel pipes of the same material and press-fit system for the non-threaded side. For the threaded side, ensure that the mating component has a matching Rp 1/2 thread. Additional components such as straight couplings, cross fittings and unions may be needed depending on the system layout. No special surface treatments or coatings are required due to the absence of limiting agents in the material.

Technical background for designers

The elbow functions as a directional transition fitting between press-fit and threaded systems. Its carbon galvanized steel construction provides good corrosion resistance in non-drinking water applications. The EPDM sealing ring ensures a tight seal under pressure and temperature fluctuations. The elbow is integrated into closed systems where thermal expansion and contraction are managed through proper support and expansion joints. Longevity depends on correct installation, avoiding over-tightening of threads and ensuring that the press-fit connection is fully engaged. The elbow is not suitable for potable water applications due to lack of certification.

Service and operation

No regular maintenance is required for this elbow under normal operating conditions. However, during system inspections, check for signs of leakage around the press-fit and threaded connections. Ensure that the molding indicator remains intact and that the press mark is visible. If the system is exposed to extreme temperatures or pressures beyond the specified range, re-evaluate the component’s suitability. No service intervals are defined in the product documentation.

Frequently asked questions

Can the IVC82.1512 be connected to a copper pipe?
No, the elbow is designed for use with seamless steel pipes and threaded steel components. Copper is not compatible with the press-fit system.

Is the elbow suitable for outdoor installation?
Yes, provided it is protected from direct weather exposure and installed according to the manufacturer’s guidelines for environmental conditions.

Can the elbow be used in solar heating systems?
Yes, as long as the system operates within the specified temperature and pressure limits and does not involve potable water.

Is it possible to reuse the elbow if it has been pressed once?
No, once the press-fit connection has been made, the elbow cannot be reused. A new component must be installed.
