3.3mm Angle Pattern

These adaptors are considered the standard within the HVAC commissioning industry. The 3.3mm needle provides adequate strength and is suitable for the majority of balancing valves currently produced throughout the world. It should be noted that the angle pattern is recommended for the ‘difficult to access’ locations. The overall length is controlled to ensure that the needle enters the waterway within the testpoint without velocity impingment from the flow of water through the balancing valve.
