Structure
Features
- 01 You can SEE, HEAR, and FEEL perfect installation Faster, Proper, Efficient, and Safter installation with i-Fitting®
- 02 With i-Fitting®, consistent and perfect installation can be accomplished by just anyone. Most tube fitting leaks are caused by improper installation.
Using i-Fitting®, you can identify the status of installation simply by using your senses.
You can ensure proper installation without needing the additional inspection of separate tools, like the gap-inspection-gauges. Rest assured that your installation is of consistent quality because you can now inspect it with your eyes and ears. Who installed it is not longer important! - 03 Improvement of productivity and cost saving i-Fitting® saves yout time by removing the need for additional inspection required for conventional tube fitting installation.
i-Fitting® saves yout time by removing the need for additional inspection required for conventional tube fitting installation. - 04 Applicable to valves The mechanism of i-Fitting® is applied to tube end connection of valves, enabling efficient and safe installation.
Mechanism
i-Fitting® lets you know that connection has been completed as the Check Ring별첨 is pushed by the nut and seperates at the exact point of perfect compression.
The Identification Band별첨 under the Check Ring helps you easily identify the status of installation with a signal that is apparent to the naked eye.

Installation Instruction
- 01 / Prepare for i-Fitting® consisting of body, back, front/back ferrule, and check ring
- 02 / Fully insert the tube into i-Fitting® and against the shoulder; rotate the nut finger-tight until the tube won't turn by hand.
- 03 / While holding the fitting body steady, tighten the nut until the check ring separates from the body.
This separation of the check ring indicates the completion of installation.

Key Valve
Key Valve (a valve that can be opened or closed with Master Key) was first developed by BMT at 2007.
Key Valve is secured against undesired manipulation that can lead to massive system failures, leakage of hazardous gases or fluids, ultimately, catastrophic damages and losses.
Features
- 01 The valve can only be operated by inserting Master Key into the handle.
- 02 Applicable to various types of valves such as ball, needle, diaphragm, and bellows valves.
- 03 Thus preventing accidents caused by inadvertent or unauthorized operation.
- 04 Ideal for populated areas and areas open to unauthorized individuals, as it prevents accidents that may come as a result of undesired manipulation.
Options
- 01 Standard type The locking function works at both open and closed positions as the Master Key is taken out from the handle.
- 02 Open Free type At fully-opened position, it is impossible to close the valve without inserting the key.
Suitable for systems where the stop of fluid flow from inadvent or unauthorized manipulation may lead to catastrophic results. - 03 Close Free type At fully-closed position, it is impossible to open the valve without the insertion of the key.
Suitable for systems where the start of fluid flow from inadvent or unauthorized may lead to catastrophic results.

Pre-formed Fitting
SUPERLOK Pre-formed Fitting was developed by BMT R&D Center in 2015
for the applications requiring higher pressure and corrosion resistance.
Mechanism
SUPERLOK Pre-forming fittings connects tubings with pre-formed grooves on their outside surface in order to remove defects on tube surfaces, and increase clamping force of tubes and ferrules. This feature offers a strong and firm grip removing various causes of leaks in tubing systems.

after installation
Features
- 01 Suitably designed for application requiring medium pressures such as hydrogen supply lines and pressurized systems using duplex, titanium, or other special alloys.
- 02 The gripping performance and leak-tight tube connections are heavily affected by tubing.
- 03 Enables more consistent and leak-tight tube connections.
- 04 The pre-formed grooves on the outside surface of the tubing offer robust tube grip and leak-tight sealing.
- 05 Applicable to tubing with defect on the outside surface, higher material strength, or heavier wall-thickness.
- 06 Available from 1/4" to 1" and from 6mm to 25mm.
Installation Instructions
- 01 Use a preforming tool to create a groove on the tube.
- 02 Insert the pre-grooved tube into the preforming fitting.
- 03 Before tightening the nut, ensure that the tubing is fully inserted and in contact with the shoulder of the fitting body.
- 04 While holding the fitting body steady with a backup wrench, tighten the nut 1-1/4 turns.
