Danfoss Nipple And Nut Playful R10

Description

Danfoss nipple and nut R10 (3/8") is an original accessory specially designed for Danfoss' market-leading RA valve series. This two-part, straight radiator coupling combines a robust threaded nipple with a freely rotating union nut (swivel connection). The design enables a quick, tight and completely stress-free assembly between the radiator and the pipe system - a prerequisite for a quiet and vibration-free heating system. The coupling is made of durable brass (CW612N) and coated with a durable, nickel-plated surface layer. The nickel-plated surface not only provides superior protection against corrosion and wear, but also creates a uniform and stylish impression together with modern radiators and thermostats.

Benefits of choosing a swivel nut

• The freely rotating nut makes installation considerably easier, especially in narrow niches, at skirting boards or close to walls where there is neither space nor possibility to rotate pipes or valve housings.
• In addition, it creates a fully demountable joint. This means that the radiator can be easily disconnected during renovation, wallpapering, painting or component replacement - without interfering with the fixed pipe system.

Benefits and Features

• Free-running nut (unscrewing nut): Enables quick, flexible and tension-free tightening without twisting the pipework.
• Guaranteed Danfoss original fit: Designed for 100% tight and problem-free connection to Danfoss RA valves.
• Durable corrosion protection: Nickel-plated brass guarantees long service life and high resistance to external wear.
• Standardized dimensioning: External cylindrical G thread according to ISO 228-1 in dimension R10 / 3/8" (DN10).
• Reliable design: Dimensioned for an approved working pressure of up to 6 bar at 20 °C in closed heating systems.

Areas of application

• Radiator installation: For connecting the supply and return on water-borne radiators equipped with Danfoss RA valve housing and coupling.
• Narrow installation spaces: Ideal for tight pipework where tool space is limited and pipes or valves cannot be turned during installation.
• Service and maintenance: Perfect solution when you want a service-friendly connection that can be easily detached for surface renovation or valve replacement.
