Ferrules in aluminium have been developed to cater for a variety of needs and applications. All aluminium ferrules are produced seamless for added safety. From size 8 and upwards they are fully traceable (ISO 9001) and marked with size, type and manufacturing batch number. Our Ferrule Securing Instructions (FSI) details the correct method of pressing, approx. pressure required and ferrule selection criteria. Our aluminium ferrules are approved by many international institutions and authorities. Details are available on request.
