Worried about vibration-induced loosening of valves/fittings in toxic gas lines?

Concerned about operational errors caused by workers?

Need a solution for preventing loosening on valves/fittings for canisters shipped by sea?

We solve all these challenges!

This patented lock device prevents the loosening of valves and fittings for both semiconductor and general industrial. applications.

It is particularly effective in preventing loosening in UHP (Ultra-High Purity) Metal Face Seal valves and fittings, which are typically tightened by the number of turns rather than a specified torque value.

2. Color-Coded Parts are available for purchase to easily differentiate lines by fluid type (gas, chemical) or function (Supply/Return).   

3. Products featuring a LOTO (Lock Out, Tag Out) function are available to prevent accidents resulting from human error by unauthorized workers.

4. Valves can also be proposed with customized specifications.

    Beyond simple anti-loosening, we offer products with added features like handle locking (to prevent accidental operation) and LOTO (Lock-Out, Tag-Out) functionality.

Our product line-up is compatible with nearly all Semiconductor(UHP) fittings 

(Metal Face Seal Fittings=VCR, CVC, FR, DCR, etc.).

Valves can also be proposed with customized specifications.

Beyond simple anti-loosening, we offer products with added features like handle locking (to prevent accidental operation) and LOTO (Lock-Out, Tag-Out) functionality.

Special Note: Fujikin (UJR or UPG) products are supported by a separate, dedicated model due to their unique specifications.
