The Right Way to Join Pipe and Tube
Gas-Tight, Permanent Seal:
The unique metal-to-metal seal of the LOKRING® connection provides extraordinary sealing
integrity in both liquid and gas services. Unlike other mechanically attached fittings, there are no elastomeric or rubber seals, O-rings or gaskets which can degrade and leak over time from chemical attack, fire, vibration, temperature cycling, cold flow or loss of elasticity.
As a result, fugitive emissions typical of leak-prone screwed or flanged connectors are eliminated.
Helium Leak Tight:
No other connector (flanged or threaded) is capable of passing helium leak testing anywhere close to the level of a LOKRING® fitting. In fact, the fitting meets all criteria of a welded connection, except that heat is not required to make the connection. The quality of a LOKRING®connection has been recognized by the California Air Resources Board (CARB) by granting LOKRING® pre-certification status through executive order G-096-029-033 which gives LOKRING® equivalent to welded status.

ESP® Elastic Strain Preload Technology: The leak-free seal of a LOKRING® fitting is the result of LOKRING Technology LLC®‘s patented elastic strain preload™ (ESP®). During installation, the axial movement of the LOKRING®driver over the fitting body swages the body onto the pipe or tube surface, compressing the pipe/tube wall, first elastically and then plastically. Installed fitting forms a perfect 360° circumferential, permanent, metal-to-metal seal.
LTCS-333: Lokring Technology released this Low Alloy Carbon Steel Solution for Sour Service applications in January 2010. Since then there has been a paradigm shift in the use of this cold-work solution being utilized in demanding systems offshore and in similar environments.
IT400 Installation Tool: FAST. SIMPLE. SAFE. Lokring Technology is proud to introduce the new IT400 installation tool. This hydraulically-actuated tool provides the ultimate in safety, efficiency, and ease-of-use, for your 4” pipe connection opportunities.
ANSI / ASME B31 Qualifications and Testing: Both stainless and carbon steel LOKRING® fittings are qualified to the requirements of the ANSI/ASME B31 pressure piping codes for pressure and fatigue design and materials of construction. Extensive mechanical and environmental testing has demonstrated the mechanical and sealing integrity of the LOKRING® connection in a wide range of applications and environmental conditions.
