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.
