This SAE Aerospace Standard establishes the requirements for a V-retainer coupling, flanges, and seal suitable for joining high pressure and high temperature ducting in aircraft bleed air systems. The rigid coupling joint assembly, hereafter referred to as "the joint", shall operate within the temperature range of -65 to +1200 °F.

Types:

The joint shall be classified into two basic flange profiles:

Type I: Standard Profile - Per MS24563 Figure 2A (1.50 to 7.50 in duct size)

Type II: Low Profile - Per MS24563 Figure 1 (1.00 to 7.50 in duct size)
