Common Fitting Torque Specification Guide
An fitting torque specs. Standard maintenance practice dictates that mechanics add this value to the specified torque. 12 inch pounds 1 foot pound these torque values apply to an connections only not flared tube or compression fittings. Never use teflon tape. Good seal but prevents damage to the fitting by over torque. Do not force an improperly bent tube into alignment figure 4 or draw in too short a tube using the nut. 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.
The table below lists the torque range for each an fitting size. This value must be added to the torque value. Here is a list of torque values for each an fitting size. 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. Aeroquip is the professionals choice and is the only company that designs engineers manufacturers and tests its hoses and fittings. Flats from wrench resistance ffwr or flats method.
Jic torque specifications. Brass and steel pipe thread npt installation procedure and torque specification table and chart. Tfft assembly turns from finger tight with pipe thread sealant or teflon tape applied. When using aluminum and steel fittings use the torque for the aluminum fitting. Liquid pipe sealant containing no teflon is the only pipe sealant recommended. 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. If valve is connected to female swivel connection refer to swivel manufacturers torque recommendation for that joint. Torque recommendations below are for valve connected to a compatible fitting adapter or block. Can you see the confusion starting. The torque required on an5 516 nuts varied between 18 22 inlbs. Torque specs for an fittings.
Sizes for rigid tubes were already standardized with sizes called out by tubing od 316 12 etc. An hose sizes were designed to match the id sizes of these rigid tubes. 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. Fluids piping and hydraulic design data. Tighten to recommended torque for the corresponding thread size from the table below.
