Voss Rigid V-Retainer Couplings and mating machined flanges are  used with  resilient,  all-metal  seals on a variety  of  aircraft  bleed air ducting for  critical  cabin pressurization, environmental and pneumatic operating systems on both commercial and military aircraft.

Standard profile Rigid V-Retainer Couplings and flanges are designed and manufactured for use primarily on aircraft jet  engine bleed air ducting and other high pressure and high temperature aircraft ducting applications. These couplings can also be used on APUs and for mounting accessories such as pumps, generators/starters and valves.

Low profile Rigid V-Retainer Couplings and flanges are designed for use in lighter weight aircraft ducting joints at intermediate-to-high pressures and temperatures up to 1200°F.
