MCLIMATE M28x1,5 - M30x1,5 patteriventtiiliadapteri (TRVM28-adapteri)

Radiator valve adapter that converts M28x1.5 valve bodies to accept M30x1.5 thermostatic heads. Brass construction provides durable, corrosion-resistant performance in central heating systems.

Advantages

Precision-machined brass threads ensure a secure, leak-free connection. The adapter enables the use of modern M30x1.5 TRV heads on older valves with M28x1.5 threads, extending compatibility without replacing the valve body.

Suitable for

• Valves with M28x1.5 thread (e.g., some older Danfoss, Herz, Comap)
• TRV heads with M30x1.5 thread (most modern standard heads)
• HVAC and central heating systems

Key specifications

• Input thread: M28x1.5
• Output thread: M30x1.5
• Material: Brass
• Finish: Natural brass
• Operating temperature: 0°C to 100°C
• Max operating pressure: 10 bar

Recommendations

Verify thread sizes before installation. Hand-tighten then use a wrench for final seating, avoiding over-tightening to prevent damage.
