## Long description

VIEGA stainless steel double union with SC 18 x 1/2 connection, polished is a threaded removable coupling designed for joining and disconnecting 1/2" SC 18 threaded pipe runs. Constructed from corrosion-resistant stainless steel with a polished finish, the union allows easy separation of piping sections for maintenance or replacement without disturbing adjacent fittings. The product is intended for plumbing and heating installations where a durable, hygienic and serviceable connector is required.
Advantages
The stainless steel construction ensures resistance to corrosion and long service life in wet and humid environments. A polished surface provides an easy-to-clean exterior suitable for visible installations and environments requiring elevated hygiene standards. The double-union design permits quick disassembly and reassembly of threaded pipes, reducing downtime during repairs. Threaded SC 18 x 1/2 compatibility allows integration with common 1/2" installations without special adapters.
Suitable for
Domestic and commercial plumbing systems with 1/2" SC 18 threaded fittings
Heating circuits and radiators where removable connections are needed
Applications requiring corrosion resistance and a polished visible finish
Service points where periodic inspection, maintenance or component replacement is expected
Key specifications
Material: stainless steel, polished finish
Connection type: double union (removable coupling)
Thread standard: SC 18 x 1/2 compatible threaded connection
Application: plumbing and heating installations
Function: enables joining and disconnection of threaded pipe runs for maintenance
How to use
Install the double union by threading each side onto the corresponding SC 18 x 1/2 male fittings of the pipe runs until hand-tight, then complete final tightening with appropriate tools following standard torque recommendations for 1/2" threaded fittings. Ensure sealing elements (if required by the system) such as PTFE tape or approved thread sealants are applied according to installation rules and local codes. To disconnect, loosen the union nut and unscrew the halves to separate pipe sections for inspection or replacement. Reassemble by reversing the procedure and verify leak tightness after reinstallation.
Usage recommendations
Use in systems compatible with stainless steel; avoid mixing dissimilar metals without appropriate corrosion control measures. Follow local plumbing codes and manufacturer guidelines for thread sealing, torque values and pressure ratings. Periodically inspect the union for signs of wear or damage and retighten or replace components as needed to maintain leak-free operation.
