An fitting torque specs. Align the tube on the flare nose of the fitting body and tighten the nut using one of the two methods below. Dont be misled by other brands that claim performance but buy their. This value must be added to the torque value. The idea behind an hoses and an fittings was to provide a flexible alternative to rigid tubing in plumbing systems on aircraft and military vehicles. The table below lists the torque range for each an fitting size. Torque specs for an fittings.
Pipe thread installation torque table chart. If valve is connected to female swivel connection refer to swivel manufacturers torque recommendation for that joint. Torque values for installing steel or malleable iron pipe plugs or fittings with pre applied loctite 516 banding are given belowall threaded connections should be lubricated before assembly. Torque recommendations below are for valve connected to a compatible fitting adapter or block. Standard maintenance practice dictates that mechanics add this value to the specified torque. An hose sizes were designed to match the id sizes of these rigid tubes.
Fluids piping and hydraulic design data. Tighten to recommended torque for the corresponding thread size from the table below. Tfft assembly turns from finger tight with pipe thread sealant or teflon tape applied. Never use teflon tape. A random sample of new and used an365 4 and 5 nuts shows that the torque required to turn an4 14 nuts varied between 15 19 inlbs. Do not force an improperly bent tube into alignment figure 4 or draw in too short a tube using the nut.
Liquid pipe sealant containing no teflon is the only pipe sealant recommended. The torque required on an5 516 nuts varied between 18 22 inlbs. 12 inch pounds 1 foot pound these torque values apply to an connections only not flared tube or compression fittings.
