At Industrial Ancillaries our range of hydraulic tube compression fittings that are suitable for heavy-duty hydraulic systems due to their ability to handle high pressure fluid flow and vibration. Hydraulic Compression Fittings work by compressing hydraulic hose with a nut that is tightened onto a ferrule, ring or gasket, creating a tight and secure seal. Available in steel or stainless steel, discover our range of hydraulic compression fittings below.
