## Long description

The SCHLOSSER inline check valve 3/8" x 3/8" is a compact, threaded non-return valve designed to permit fluid flow in one direction while preventing backflow in piping systems. Manufactured for general fluid installations, this model is suitable for water and heating circuits and fits standard 3/8" female threaded connections. The valve body and internal components provide straightforward integration into residential and light commercial plumbing where a small-footprint, reliable check function is required.
Advantages
This check valve offers a compact form factor and simple threaded connections for quick installation into existing 3/8" lines. The design ensures unidirectional flow control without the need for external power or active control, reducing complexity in piping layouts. Its construction is intended for typical water and heating applications, providing dependable prevention of backflow and helping to maintain system pressure and hygiene. The valve's compatibility with common fittings makes it versatile for a range of plumbing setups.
Suitable for
Residential water supply lines
Heating system circuits and radiators
Under-sink and appliance connections
Light commercial plumbing installations
Key specifications
Connection size: 3/8" x 3/8" threaded
Type: Inline check (non-return) valve
Application media: Water and typical heating fluids
Installation orientation: Inline, for unidirectional flow
Typical use: Residential and light commercial plumbing systems
How to use
Install the valve inline between two compatible 3/8" threaded fittings, ensuring the flow direction marking on the valve matches the intended direction of fluid movement. Use appropriate thread sealing material or tape on the male threads to ensure a leak-free joint. Tighten connections with suitable tools without over-torquing to avoid damaging the threads or valve body. After installation, run the system and check for leaks and correct operation by verifying that fluid passes only in the intended direction and that no backflow occurs when downstream pressure changes.
Usage recommendations
For best performance, select the valve for use with clean water or compatible heating fluids and avoid abrasive or heavily contaminated media. Inspect and service the valve periodically as part of routine plumbing maintenance, and replace it if internal wear, leakage, or reduced sealing performance is observed.
