This standard specifies the characteristics of gasket seal with nickel alloy C seal on heat resisting steel,
3 holes, for pipe couplings for inch series aerospace applications.
Nominal pressure: up to 21 000 kPa; depends on the associated tube material and tube wall thickness in the assembly (see EN 4814).
Temperature range: −55 °C to 600 °C.
NOTE Assembly in accordance with TR 4815.
This part should not be reused after disassembling.
