SG-LOK Korea Malaysia Supplier/Distributor

Features

SG-LOK tube fittings have been specifically designed for use on instrumentation, process and control systems and equipment employed in chemical, petroleum, power plant, ship building, semiconductor and solar industries. SG-LOK tube fittings could also be used in applications of other fields where very high quality tube fittings are required.

Construction

SG-LOK tube fittings are composed of body, nut, front ferrule and back ferrule. When the nut is screwed forward, the back ferrule advances the front ferrule along the taper of the body, resulting in a tight grip on the tube and no leaks.

Materials

SG-LOK tube fittings are available in various kinds of materials.  Straight fittings are machined from cold finished bar stock and shaped fittings from forgings.
