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

16、 assembly per AS5550 installed per this document into ports prepared 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” i

17、n Figure 2 and Table 2A. 3.4 O-ring size per Tables 1A and 2A 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 fittin

18、g reducer assembly have been torqued. This prevents the 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 rem

19、oval is accomplished by lifting the lockring out of the 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 insta

20、llation. Tooling must be certified to have been used during the qualification of fitting assemblies.
