bulletThe LOKRING Tube Joining System represents a proven method of producing hermetically sealed metal-to-metal tube connections without brazing, welding or threading.
bulletLOKRING Single Rings are engineered to exact specifications for each application.
bulletJoin tubes with a maximum wall thickness of 1.5 mm
bulletLOKRING Single Rings are designed for maximum operating pressure of Pn = 50 bar (725 psi) and testing pressure of Pp = 4 x Pn = 200 bar (2900 psi). LOKRING Tube Connectors can be used in a temperature range between -50°C and +150°C (-58°F and +302°F).
bulletExpansion or contraction of the material caused by change in temperature has no impact on the elasticity of the tube connection. Burst tests have shown that the LOKRING Connection is stronger than the burst point of the tube
bulletLOKPREP, an anaerobic sealer containing methacrylic ester, is required for all LOKRING connections to fill any blemishes on the tubes.
