Screw Cap Seal KD-550
Drip leaks at screw caps on rail tank cars cause journey interruptions, delays and fines. The screw cap seal KD-550 developed by VENTAIX reduces this risk to a minimum with a double seal - it tolerates moderate contamination and unevenness and does not require a high, damaging tightening torque. Suitable for any common 5½" screw cap and easy to retrofit.
Fewer Drip Leaks, Lower Costs
Drip leaks are a frequent reason why the transport of liquid hazardous goods does not run smoothly. Insufficient sealing of the protective cap closing the filling and discharge line makes journey interruptions necessary, resulting in delays and fines. The causes of drip leaks are numerous. Damaged sealing seats, failing flat gaskets or corroded pipe ends are some of the technical defects that frequently occur. Solid particles from the rail tank car or contamination inside the screw cap are also known sources of failure.
The novel seal set for screw caps of this type developed by VENTAIX reduces the probability of a drip leak occurring to a minimum. The double seal used tolerates moderate contamination and unevenness on the sealing surfaces. It provides protection against leaks of various origins even without tightening the screw cap with high torques that would damage the cap and the thread.
Easy Retrofitting
Any common screw cap with a 5½" thread used on rail tank cars can be retrofitted with the VENTAIX seal set without major effort.
