## Summary description

Straight brass union (3/4") by kfa², model 814-010-20. A plumbing fitting designed to connect or extend pipes with a 3/4-inch thread, made of corrosion-resistant brass for durability. Suitable for water installations, heating systems and plumbing repairs where a reliable threaded straight connector is required.

## Long description

Straight brass union 3/4" by kfa², model 814-010-20, is a threaded plumbing fitting designed to join two sections of pipe with a 3/4-inch thread. Manufactured from corrosion-resistant brass, the union provides a durable, conductive and dimensionally stable connection suited to water supply lines, heating circuits and general plumbing maintenance. The straight design keeps flow direction unchanged while enabling disassembly for servicing or replacement without cutting pipes.
Advantages
The brass construction offers good resistance to corrosion and scaling in potable water and heating applications, ensuring long service life. The straight union design provides a secure threaded connection that is easy to install and dismantle when maintenance or replacement is required. Compatibility with standard 3/4" threaded pipe fittings simplifies integration into existing systems. Its compact form factor allows installation in confined spaces where a straight coupling is needed.
Suitable for
 Joining or extending 3/4" threaded water supply pipes
 Connections in central heating and radiator circuits
 Plumbing repairs and temporary or permanent pipe couplings
 Use where threaded disconnection for maintenance is required
Key specifications
 Type: straight union (threaded coupling)
 Thread size: 3/4" (compatible with standard 3/4" threads)
 Material: brass (corrosion-resistant)
 Application: water supply, heating systems, general plumbing
 Connection: male/female threaded joint designed for disassembly
How to use
Prepare the mating pipe threads by cleaning and, if required, applying suitable thread sealant such as PTFE tape or liquid thread sealant rated for potable water and heating systems. Hand-start the threads to avoid cross-threading, then tighten with an appropriate wrench until a firm, leak-free joint is achieved; avoid excessive torque to prevent thread damage. If used in heating systems, observe system pressure and temperature limits defined by the overall installation components. For disassembly, loosen the coupling with a wrench and separate the threaded ends; inspect sealing surfaces and reapply sealant before reassembly.
Usage recommendations
Use compatible thread sealants and ensure threads are undamaged before installation. Verify that the brass union is appropriate for the fluid and temperature range of your system; consult system component specifications when necessary. For potable water installations, use sealants and installation practices compliant with local regulations and standards.
