3 Tips to Stop Air Leakage at 4V210-08 Fitting Joints

Seal It Tight: Preventing Fitting Leaks on the 4V210-08

Even a tiny hiss from your Airtac 4V210-08 means wasted energy. Most leaks happen at the fitting interface, not inside the valve.

1. Cut the Tube Square

Always use a dedicated tube cutter. If you use scissors or a knife, the tube end will be oval or jagged, preventing the internal O-ring of the push-in fitting from sealing against the 4V210-08 port.

2. Check the Thread Seal

For G-thread (Parallel) ports, ensure the plastic or copper washer is seated flat. For NPT (Tapered) threads, ensure the Teflon tape starts after the first thread to prevent it from entering the valve body. Regular inspection of these joints at Airtac-Shop.com saves hundreds in compressed air costs annually.
