Lokring & Lokclip

The lokring system is the innovative, time saving solution for joining aluminium, copper and steel pipes and making a/c hoses. This outstanding system, was developed in conjunction with NASA for spacecraft fuel lines. With the lokring system, you are able to cut hard steel and aluminium pipes and join them together, including going from hard pipe to flexible rubber hose. 

• Made in Germany
• Will join any material to any other material. e.g. aluminium to steel, making the system extremely versatile.
• Leakage free - Due to a unique joining system that seals every time, the first time! You use the same fitting for metric and imperial pipes. Joins are rated at a working pressure of 5,000 kPa or 20,000 kPa maximum pressure.
• A simple 6 step process that takes only minutes, means better service for the customer and more profit for you. The join is ready to use immediately and the system can be charged.
• Can also be used for many other areas including power steering lines, fuel lines and transmission lines - the same connectors will also be utilised.
