LOKRING® fittings are ideal for small pipe installations by eliminating the need to weld or thread. A metal-to-metal seal is created without the use of elastomeric or rubber seals, O-rings, or gaskets, thus making LOKRING ideal to use in high temperature and pressure applications for gas and liquid. LOKRING fittings have been pressure-torsion tested, flexural tested, and fire tested and meet all classification society requirements including NAVSEA.
