Double connector with SC 42 x 2 bronze / polished, model 2263 305031

Safe transition from copper pipe to thread

This component connects press-fit systems with traditional threaded installations, eliminating the need for additional adapters. On one side, it features a press-fit sleeve designed for pipes with an outer diameter of 42 mm, while the other side has a metric internal thread with a nominal diameter of 2 inches (50 mm). Thanks to this solution, the installer can quickly and permanently connect copper pipes to fittings, valves, or other threaded components, maintaining the tightness of the entire circuit.

The material of construction is bronze (or silicon bronze), ensuring corrosion resistance in typical water and heating installations. The assembly is equipped with pre-mounted seals made of ethylene-propylene-diene monomer rubber (EPDM), ready for immediate use. Special attention should be paid to the nut construction, which is made of brass, increasing mechanical strength during tightening and preventing damage during installation.

Application and operating conditions

This component is suitable for installations requiring a connection between a press-fit pipe and a threaded element for potable water, central heating, and technical systems. Due to the materials used and flat sealing, the component is designed for operation at a working pressure of up to 16 bar at 20°C. In heating installations, the permissible operating temperature can reach up to 110°C.

A key safety aspect is the use of SC-Contur technology. Thanks to this profile on the press-fit sleeve, any improperly made (unmarked) joint is immediately detected during the system tightness test. This system guarantees detection of installation errors in both water tests (in the range of 1 to 6.5 bar) and air tests (from 0.022 to 3 bar). This is a significant convenience for installation teams, eliminating concerns about "accidental" leaks resulting from carelessness during pressing.

Installation and technical benefits

• Connection versatility: Connects a copper pipe Ø42 mm with a metric thread G2", which is a common requirement when connecting boilers, heat exchangers, or main valves.
• Error prevention: The SC-Contur profile acts as a quality safeguard – if the connection is not properly pressed, the pressure test will immediately reveal the issue.
• Sealing durability: The EPDM seal ensures long-term tightness across a wide temperature range and requires no additional lubrication or surface preparation before installation.
• Compact design: With a total length of 56 mm, the component occupies minimal space in distribution cabinets or technical spaces, facilitating installation in hard-to-reach areas.
• Compliance with standards: The product holds a VdS certificate, confirming its suitability for fire protection installations and compliance with rigorous safety requirements in industrial and public utility construction.

It is important to remember that during installation, dedicated pressing heads compliant with the Profipress standard for 42 mm diameter must be used. This connection is intended for both visible (exposed) installations and those concealed within walls or ceilings, provided appropriate clearances from combustible materials are maintained according to the system manufacturer's instructions. Parameters such as a maximum working pressure of 16 bar and an allowable temperature of up to 110°C in heating installations define its safe application range in various industrial and domestic environments.
