Abstract
A gas turbine engine includes a compressor section. A diffuser case is downstream of the compressor section. There is a combustor and a turbine section. A bearing compartment is inward of the combustor. A shaft connects the turbine section to the compressor section. The bearing compartment includes a bearing that supports the shaft. A plurality of tubes extend to the bearing compartment. Each of the plurality of tubes have a heat shield that includes a first half and a second half crimped together along lateral edges.
