A tube coupling assembly is disclosed, which comprises a first connector for connecting to a tube; a second connector for jointing with the first connector; a first member is adapted to mount on the first connector and operably affixable to the second connector; and a second member is adapted to mount on the second connector, and is capable of being engaged with the first member to prevent separation between the first connector and the second connector.

Tube coupling assembly

A feeder duct assembly for a gas turbine engine, which negates the need for a ball or axial joint in the duct for required for flexibility under thermal loading. The feeder duct assembly of the present innovation comprises an end fitting designed to meet flexibility requirements without compromising dynamic performance of the system with added weight from ball or axial joints in the ducts.

The present disclosure is directed generally to firewall seals for sealing pass-through members extending through a firewall, such as a firewall of a turbine engine. In one example aspect, the firewall seal includes quick-connect features that facilitate more efficient assembly and disassembly of the firewall seal to and from the pass-through member. Particularly, the firewall seal may define a slit extending through at least a portion of the seal that allows for the pass-through member to be slid through the slit and positioned in place. A retainer formed of an elastomeric material may include a metal spring plate that springs the seal back into place after the pass-through member is positioned within the seal. Moreover, a spherical bearing of the firewall seal may include features for receiving a static or dynamic pass-through member therethrough and for allowing the pass-through member to translate and rotate.
