GENERAL DESIGN INFORMATION 3.1 These fitting assemblies provide a semi-permanent male fitting for use in fluid systems of 5080 psi and compatible with titanium at -65 to +230 F temperature range. 3.2 Fitting assembly per AS5550 installed per this document into ports p

13、repared per Section 5 shall have stand-off dimensions “P” and “R” in Figure 1 and Table 1A. 3.3 Fitting reducer assembly per AS5865 installed per this document into ports prepared per Section 5 shall have stand-off dimensions “P” and “R” in Figure 2 and Table 2A. 3.4 O-ring size per Table 1A and Tab

14、le 1B must be used. The O-ring compound shall be specified by the using design activity and shall be selected based on system fluid and temperature. 3.5 The lockring is driven into the mating port serrations after the fitting assembly or fitting reducer assembly have been torqued. This prevents the

15、fitting assembly from rotating in the port during coupling nut assembly and disassembly and also eliminates the necessity of lock wiring the fitting. Only one wrench is required to install or remove coupling nut. 3.6 Fitting assembly AS5550 removal is accomplished by lifting the lockring out of the

16、port using a removal tool per Table 1B. 3.7 Fitting reducer assembly AS5865 removal is accomplished by lifting the lockring out of the port using a removal tool per Table 2B. 3.8 These fitting assemblies require special tooling for proper installation. Tooling must be certified to have been used dur

17、ing the qualification of fitting assemblies. Tooling is available from Alcoa Fastening Systems, Fullerton, California, USA - CAGE Code 66776; or equivalent alternate source (Faber Enterprises, Canoga Park, California, USA - CAGE Code 14397, or Shur-Lok Company, Irvine, California, USA CAGE Code 9739

INSTALLATION OF FITTING ASSEMBLY AS5550 INTO PORT 6.1 O-ring Installation 6.1.1 Place the O-ring (per Table 1A)

41、 over the small thread of the fitting assembly. Submerge the O-ring tool and O-ring in the fluid to be used in the working system, or a lubricant compatible with the system fluid and all components. Slide the O-ring over the O-ring tool and onto the fitting assembly. Be sure that the O-ring is not t

42、wisted and is properly seated in the groove of the fitting assembly. See Figure 4. FIGURE 4 - O-RING INSTALLATION 6.1.2 Remove the O-ring tool. 6.2 Install Fitting Assembly Into Port 6.2.1 Lubricate the internal surfaces of the port using the same fluid or lubricant as specified in 6.1.1. Scratches,

43、 dings or rough spots are not allowed in O-ring contact area on the fitting assembly or in the port. 6.2.2 Insert the port end thread of the fitting assembly into port by hand using a clockwise rotation until the fitting assembly is seated. To avoid possible O-ring damage, the fitting assembly shoul

44、d not be rotated in a counterclockwise direction.

45、age the serrations of the tool with the external serrations of the lockring per Figure 5. Place a torque wrench of the proper size over the hex of the wrench and apply a torque equal to the minimum value specified in Table 1A. Note the relationship of the lockring serrations with respect to the preb

46、roached serrations in the port. If they match, proceed to 6.2.4. If the lockring serrations do not match the prebroached serrations in the port, continue to slowly torque toward the maximum value allowed in Table 1A until the serrations match. This will normally take between 3 degrees and 8 degrees

47、of turning, the maximum value need not be reached if the serrations align themselves prior to that value. Do not exceed maximum torque values. FIGURE 5 - TORQUING FITTING ASSEMBLY 6.2.4 Apply enough zinc chromate primer (TT-P-1757) with a brush or small syringe to the counterbore area of the port an

48、d below the lockring so primer will be extruded out between external serrations of the lockring and serrations in the port when lockring is installed. NOTE: Using design activity may specify another primer in place of, or in addition to, zinc chromate (see 4.1.7).
