Applications: Precision Cutting, Welding etc.

For pipe connections to Welding, Gas Cutting, Plasma Cutting Machines and Safety Locks for Gas Regulators
Double safety lock
Our patented safety lock design system prevents connections being disconnected from socket due to unexpected external forces and vibrations during operation. The design feature allows applications not only in general welding, gas-cutting in-door application but also in severe operating conditions in outdoor applications.
Double Sealing Construction
Our innovative patented double safety sealing construction eliminates gas leakage while connecting plug into socket
Backflow Prevention and Anti-inflammatory Plug (PAC/ PTC)
The design construction has inbuilt safety features that operates stop check valve when reverse gas flow is generated due to any trouble at welding, cutting side of the machine. This prevents gas mixing.
Quality and Function
The components are manufactured with precision quality control. The components are 100% tested for leakage detection with advance technology equipments. Built-in quality and design features ensure high safety standards, excellent operation performance and durability. Design allows ample gas flow to meet application requirements.

Three points about One-touch lock type connector
While connecting socket to plug Connect plug into socket by pushing both sides, holding the parts except the sleeve. At connection there will be "Click" sound and sleeve moves a little.
Safety lock operation Rotate locking collar up to stop position for secured locking.
While disconnecting socket and plug move locking collar down to unlock position and push sleeve towards the plug. This will disconnect plug from the socket.
