Ferulok Straight FBU

The Ferulok fitting design utilizes a combination of proven European features, coupled with many innovative product improvements instituted by Parker Hannifin. On assembly, the ferrule “bites” into the outer surface of the tube with sufficient strength to hold the tube against pressure, without significant distortion of the inside tube diameter. Ferulok fittings are especially suitable for use with tube wall thickness ranging from medium to extra heavy.
