A seal includes first and second axially opposite loops integrally joined together by a coextensive web in a collective ring having a circumferential split. The two loops are arcuate in section, with radially outer and inner sealing lands. And, the web is disposed radially between the outer and inner lands. The loops are disposed in corresponding grooves of adjoining members for effecting a seal therebetween and accommodating differential radial and axial thermal movement.

[What is claimed is:] [1.]first and second axially opposite loops integrally joined together by a coextensive web in a collective ring having a circumferential split and uniform gauge;said first loop being arcuate in section, with radially outer and inner sealing lands sized to engage a first annular groove extending axially in said first member for accommodating said axial excursion;said second loop being arcuate in section, with radially outer and inner sealing lands sized to engage a second annular groove extending axially in said seond member for accommodating said axial excursion; andsaid web being disposed radially between said outer and inner lands of said first and second loops for reducing bending moment of inertia to permit twisting of said seal to accommodate said radial excursion.
