Abstract
A fastener assembly for connecting a fuel pipe to an engine component. The fastener assembly includes a housing and a fastener positioned within the housing. The housing has an end surface with an aperture for receiving a fuel pipe therethrough. At least one side wall extends from the end surface to define a recess for receiving a fastener therein. The fastener has a pipe inlet for receiving a fuel pipe therethrough, and a connecting arrangement for connecting the fastener to an engine component.
Claims16
A fastener assembly for connecting a fuel pipe to an engine component, the fastener assembly comprising:
- a housing comprising an end surface having an aperture for receiving a fuel pipe therethrough, in use, and at least one side wall extending from the end surface, wherein a distal end of the at least one side wall defines an open end of the housing and wherein the end surface and the at least one side wall define a recess for receiving a fastener therein;
- and
- a fastener positioned within the housing, the fastener comprising a pipe inlet for receiving a fuel pipe therethrough, in use, and a connecting arrangement for connecting the fastener to an engine component;
- and
- wherein the housing comprises a first seal member configured to seal the aperture against an external surface of a fuel pipe extending therethrough, and a second seal member configured to form a second seal with an external surface of a fuel pipe when in use, the second seal member being separate from the first seal member.
