DIN Unions

DIN unions (German institute for standardisation) are used in conjunction with German and other European equipment. They are manufactured in accordance with DIN 11851 (EN10357) and our standard range consists of a round slotted nut, weld liner, weld male, blanking cap, blanking cap and chain, weld liner x hose tail and seals which are available in a range of materials and sizes listed below. We may also be able to manufacture to specific requirements upon request.

Both imperial and metric DIN unions are also available to purchase online by clicking the 'Buy Online' button above.
