We are offering hydraulic fittings.me' bite type fittings manufactured to din2353 / iso8434 - 1 for ease of interchangeablity and to maintain high quality standards. Each fittings are precisely machined and checked thoroughly to achieve consistent high quality. Wide selection of material and configuration suits every applications and ensures leak proof piping & easy pipe layout. Heat treatment of ferrule ensures perfect bite & assembly. me' single ferrule fittings are manufactured to suit mm od tube [din2391 c], od tube & nb pipe as well. technical specifications 24 standard: din 2353 / iso 8434 - 1 & iso 8434-4 [weld nipple type] series & pressure range: ll series - 100 bar, l series - 250 bar max, s series - 630 bar size: 4mm to 42mm od, 1/4"od to 2"od, 1/8"nb to 2"nb material of construction carbon steel, ss304, ss316, brass (from solid bar stock / forged body) surface treatment: phosphates, trivalent (chrome vi free), zinc bi - chromated (a3c) principle:me' single ferrule tube fittings consists of :1] coupling nut2] ferrule - cutting ring3] body as the coupling nut is tightened, the ferrule moves along the tube. When the ferrule outside diameter contacts the inner taper of the coupling body, the front cutting edge of the ferrule makes the primary bite cleanly into the outer surface of the tube. At the point where the secondary bite comes into contact with the surface of the tube, a sharp increase in torque will occur. This signals to the operative that a perfect, pressure-tight joint has been achieved and no further tightening is necessary. At the same time, the ferrule is clamped firmly by the nut on the tube providing a perfect anti-vibration lock. advantage of 'me' single ferrule fittings:cnc machined component ensures high quality finish & excellent qualityin house qap ensures consistent qualitywide range to suit every applicationsconfirms to din2353 / iso 8434 -1right quality, at right time & at right price 'me' tube fittings are passed following tests:visual checkdimensional checkproof pressure test third party inspection offered on request
