Abstract
Arrangement for sealing an opening in a solar collector through which a header passes and for maintaining the integrity of the seal during movement of the header due to expansion and contraction thereof. A generally cylindrical resilient member compressively engages an adapter member defining the opening at a first annulus of contact and tapers to compressively engage the header at a second annulus of contact. In an alternate embodiment, the resilient member then flares to a third annulus of contact at the adapter. Apparatus is also disclosed for connecting and sealing the headers of adjacent collectors or a header to a manifold.
