## Summary description

Compression fitting for pilot (impulse) tube by DANFOSS, model 003Z0109, adapting thread size G3/4 to G1/16. Designed for use with ASV and AB‑PM series valves, this fitting provides a threaded transition between larger G3/4 connections and smaller G1/16 pilot lines. Suitable for HVAC and refrigeration control systems requiring reliable pilot line connection.

## Long description

Compression fitting for pilot tube DANFOSS G3/4 to G1/16 is a metal adapter designed to create a secure threaded transition between a larger G3/4 connection and a smaller G1/16 pilot (impulse) line. Intended for use with ASV and AB‑PM series valves, the fitting enables reliable connection of control and sensing lines in HVAC and refrigeration systems where accurate pilot signaling and leak-tight joints are required.
Advantages
This compression fitting provides a compact and robust mechanical connection that simplifies installation of pilot tubing on valves. Its precision-machined threads ensure consistent mating with G3/4 and G1/16 ports, while the compression-style sealing minimizes the need for additional sealing materials. The design supports repeated assembly and disassembly without compromising thread engagement, making it practical for service and maintenance work on refrigeration and air-conditioning control assemblies.
Suitable for
Connecting pilot/impulse tubing to ASV and AB‑PM series valves
Retrofit and repair tasks in HVAC and refrigeration control loops
Applications requiring conversion from G3/4 valve ports to G1/16 pilot lines
Key specifications
Thread transition: larger G3/4 to smaller G1/16
Type: compression fitting for pilot/impulse tube
Material: metal construction suitable for refrigeration/HVAC service (corrosion-resistant finish)
Compatibility: designed for use with ASV and AB‑PM valve families
Application: control and pilot line connections in refrigeration and air-conditioning systems
How to use
Install the fitting by threading the larger G3/4 end into the valve port and tightening to the manufacturer’s recommended torque to ensure a leak-tight joint. Insert the pilot tube into the compression side until it seats fully, then secure the compression nut to create the seal. Follow standard practices for pilot tubing routing and secure tubing to avoid strain on the connection during operation. When servicing, loosen the compression nut to remove the tube and reassemble carefully to maintain sealing performance.
Usage recommendations
Use appropriate thread sealant or PTFE tape only where specified by system guidelines; avoid over-tightening to prevent thread damage. Verify compatibility of tubing material and wall thickness with the compression fitting. Inspect connections periodically for signs of corrosion or leakage, especially in systems exposed to moisture or refrigerant oils.
