SOL-ARM SOL-ARM KOREK MOS. 3/8'' – brass drain cock 3/8" for plumbing and heating systems

SOL-ARM KOREK MOS. 3/8" is a brass drain cock designed for plumbing and heating systems. The compact 3/8" connection provides a durable shut-off and controlled drainage point for radiators, boilers, pipes and valves. Made of brass, the valve is suitable for potable water and central heating applications where a reliable drainage or service access point is required.

Advantages

The brass construction ensures corrosion resistance and long service life in typical domestic and commercial heating and plumbing environments. The 3/8" connection size allows for compact installation in tight spaces and straightforward replacement of existing drain fittings. The design provides secure closure to prevent leaks while enabling controlled draining during maintenance and repairs.

Suitable for

• Radiator bleed and drainage in central heating systems
• Boiler and hot-water system maintenance and draining
• Localised draining of piping and fittings during installation or repair
• Use with potable water systems where brass fittings are acceptable

Key specifications

• Material: brass
• Connection size: 3/8"
• Function: shut-off and drain cock
• Application: plumbing and central heating systems
• Suitable media: potable water and heating fluids
• Compact form factor for installation in tight spaces

How to use

Install the drain cock into the corresponding 3/8" female fitting on radiators, boilers or piping using appropriate sealing material or tape to ensure leak-free joints. Tighten securely with suitable tools without over-torquing to avoid damaging threads. To drain, open the valve slowly to control flow; close fully after maintenance. Periodically operate the cock to verify functionality and prevent seizing from mineral buildup.

Usage recommendations

Use compatible thread sealant and ensure system pressure is reduced or isolated before installation or draining. For potable water systems, confirm brass suitability with local regulations and avoid prolonged exposure to highly corrosive media. If uncertain about installation, consult a qualified plumber or heating engineer.
