## Long description

Straight brass coupling 3/8" for plumbing kfa² 814-010-10 is a precision-made connector intended for joining or extending 3/8" threaded plumbing pipes and fittings. Manufactured from brass, this straight coupling provides corrosion resistance and mechanical stability suitable for potable water supply, heating circuits, and general sanitary installations. The product is compatible with standard 3/8" threaded connections used in residential and commercial plumbing systems and is intended to ensure a reliable sealed joint when installed correctly.
Advantages
The brass construction offers natural resistance to corrosion and scaling while maintaining dimensional stability under typical water temperatures and pressures. Its straight design enables a compact inline connection with minimal flow disruption. The coupling's machined threads ensure accurate mating with compatible 3/8" fittings, which simplifies installation and reduces the need for frequent rework. The material and finish also support long service life in common plumbing environments.
Suitable for
Joining two 3/8" threaded pipes in water supply systems
Extending existing 3/8" plumbing runs
Connecting fittings in heating loops and radiator assemblies
Installation in bathrooms, kitchens, and utility rooms for sanitary fittings
Key specifications
Connection type: straight coupling for 3/8" threaded pipes
Material: brass for corrosion resistance
Application: potable water, heating, and sanitary installations
Design: inline straight connector to maintain flow alignment
Surface: machined finish suitable for reliable thread engagement
How to use
Ensure mating threads on pipes or fittings are clean and free of debris before assembly. Apply appropriate thread sealant or tape if required by the installation standards in your region. Hand-start the coupling onto the first 3/8" threaded component, then tighten to the recommended torque using suitable tools to avoid over-tightening and deforming threads. Align the second 3/8" component and complete the connection, checking for proper alignment and engagement. After installation, pressurize the system and inspect for leaks at the joint; retighten or reseal if necessary following local plumbing practice.
Usage recommendations
Use compatible 3/8" fittings and observe local plumbing codes. Avoid excessive torque during tightening to prevent thread damage. For systems carrying drinking water, use approved thread sealants and perform a pressure test after installation to confirm leak-free joints.
