DK-Lok LogoDK-Lok Tube Fittings have been designed specifically for the many demanding application chemical, petroleum, power generating, pulp, paper and various types of manufacturing industries. They provide a highly reliable, leakproof and torque free seal on all tubing connections.

DK-Lok Tube Fittings are commonly used on instrumentation, process and control systems or any other application where a high quality tube fitting is required.

Standard Quality for DK-Lok Fittings

The DK-Lok body, nut, back ferrule and front ferrule are manufactures under very close tolerance control and monitored through Statistic Process Control and are Heat-Code Traceable.

The twin ferrule design performs leak proof sealing with all assembly and reassembles motion being transmitted axially through the tubing. This results in no radial movement of the tubing upon assembly and reassembly. Therefore the tubing is not stressed and the mechanical integrity is maintained. Through this swaging action, the DK-Lok fitting becomes integrated mechanically with the tubing connected.

DK-Lok fittings are available in Stainless Steel, Brass and Carbon Steel as standard materials and can be manufactured from various materials upon request.
