Hydraulic fittings are available in many shapes. As you can see on our site, there are single ferrule and double ferrule products. Although both systems are resistant to high pressure, it is preferred according to the field of use. The connection element to be selected is decided according to the type of substance to pass through. Although there is no difference in the performance of both products in many cases, but double ferrule products work better in gas systems. If you do not have a gas passing system, in terms of price performance, single ferrule products are more cost effective. Please, request a offer for the stainless steel double ferrule fittings you need.
