Kobs India are well known manufacturers , traders and suppliers of Caps in India and Abroad.

The function of an end cap is to block the endings of piping systems. This is done by fixing the end cap over the open end of pipe and welding around the point.


A lap joint stub end and its associated slip on flange in piping systems allows spontaneous disconnection of a particular section involved. Stub ends are usually installed in pairs & then mated together with two lap joint flanges. The surface of the stub end has a phonographic serrated gasket surface which prevents leakage of the joins. Using stub ends allows section of the line to be opened for cleaning purposes. Inspection or quick replacement etc, without the need to re-weld again.There are two basic types of sub end, M.S.S. short barrel and A.S.A. long barrel. Under certain design criteria such as temperature or pressure etc, It is not favorable to have the joint between stub end and pipes in close proximity with the flange joints; in these applications A.S.A. types are used. We are also dealing in crafting of caps and stub ends to serve the best functionality. Premium quality raw materials are used to craft these caps as well as stub ends which add strength and durability to all these products. All these steel butt weld cap and stub end fittings are excellently serving the purpose. We offer these caps & stub ends at market leading rates to our clients.
