Improved Safety

• Tamper proof; LOKRING is designed as a permanent joint.
• Risk of fire or explosion due to hot work is eliminated.
• No fumes or smoke are produced, eliminating the need for special ventilation and creating a safer environment particularly in confined spaces.
• No hazardous materials are used in the process, created by the process or required to be disposed of after the process is complete.
• No welding or grinding is required thus reducing the potential for injuries.
• Fabrication of piping systems utilizing LOKRING fittings are “intrinsically” safe since no torches, open flames or sparks are associated with installation or maintenance.

Improved Quality

• Install and inspect marks provide post-installation quality control through visual verification of installers' work.
• Joint reliability is “machined into” and not reliant on the skill or “touch” of the welder/brazer.
• The position and the presence of liquids (e.g. oil, fuel or water) do not affect the joint quality.
• Redundant metal-to-metal seals produce a gas-tight connection that is safe for services in fire hazardous areas and systems. The seals will not melt or degrade during fire.
• Installation is a “cold work” process thus eliminating the heat affected zone and the deteriorated metallurgical properties associated with such zones.
• Rework is drastically reduced or eliminated.

Increased Productivity

• Gas-freeing tanks and spaces are not required.
• Installation times are a fraction of that required by conventional methods.
• No hot work means no running chits, no fire watches and no disruption from events that stop hot work (e.g. ammo loading, painting, hot oil flushes, fuel spills, etc.).
• Fittings may be installed in a system that is not or cannot be thoroughly drained and dried.
• Joint inspection is visual only; no NDT is required!
• Minimum training and qualification requirements reduce time off of the job and training costs.
• Flushing requirements from brazing or welding are completely eliminated.
• Inter-trade disruption is reduced.
• Damages to surrounding wiring, tile, equipment and painted surfaces are eliminated.
• Reduced installation times result in schedule flexibility and lower installed costs.

Lower Installed Costs

• A combination of productivity and reliability, coupled with low overhead and low rework, result in lower overall installed cost and accelerated job completion.

Improved Productivity and Job Scheduling

• LOKRING fittings can be consistently installed in the field at a rate of approximately 10 times faster than equivalent weld connections.
• LOKRING fittings can be installed in any weather conditions, indoors or outdoors, with no loss of productivity.
• Eliminates or significantly reduces welding-related costs such as hot work permits, the building of weld boxes, welder availability, and plant downtime.
• Eliminates the need to purge (“gas free”) process lines as required for hot work.

Repeatable, Reliable Connections

• The LOKRING system requires only a minimum of skill to install and maintain a leak-free system the first time.
• The quality of the system is “designed into” the fitting – independent of the installer.

Easy Access - Closed Space Pipe Runs

• Compact, lightweight hydraulic installation tools require only one-plane of access on fitting application.
• Closely spaced pipe runs can be fabricated or repaired using LOKRING fittings. A 2” NPS pipe can be run on as little as 3 ½” centers.

Low Overhead - Tooling is Inexpensive

• Tooling is inexpensive and lightweight, power requirements are minimal; no need for pipe threading, purging, flushing or welding equipment.
• Field fabrication greatly reduces the need for expensive isometric drawings and shop pre-fabrication expenses.

Low Rework - Less than 0.1%

• Repair with LOKRING's through-bore designs are as simple as cut, slip fitting over pipe, and LOK!
• Historical rework rates for LOKRING fittings are less than 0.1% of all installations compared to 5% - 10% for welded installations.
• Zero contamination in the tube or pipe connections eliminates flushing requirements.
