Abstract
Official abstract text for this publication.
A compression collar is used for reinforcing an interference fit between a piping end and a fitting. The compression collar comprises a reinforcing ring having a tubular geometry with a radially-inward facing surface and a radially-outward facing surface. A sleeve is received around, at least in part, a portion of the radially-outward facing surface of the reinforcing ring and this sleeve wraps around one axial end of the reinforcing ring to form a stop edge thereon.
First claim
Opening claim text (preview).
What is claimed is: 1. A compression collar for reinforcing an interference fit between a piping end and a fitting, the compression collar comprising: a reinforcing ring having a tubular geometry with a radially-inward facing surface and a radially-outward facing surface, the reinforcing ring configured to remain in place about the piping end after expansion of the compression collar due to expansion of the piping end; and a sleeve received around, at least in part, a portion of the radially-outward facing surface of the reinforcing ring and wrapping around one axial end of the reinforcing ring and extending radially inwardly beyond the radially-inward facing surface of the reinforcing ring to form a stop edge thereon, the sleeve including a perforation such that the sleeve is configured to tear upon expansion of the compression collar due to expansion of the piping end. 2. The compression collar of claim 1 , wherein the sleeve comprises a different material than the reinforcing ring. 3. The compression collar of claim 1 , wherein the sleeve comprises a polymeric material configured to shrink when exposed to heat. 4. The compression collar of claim 3 , wherein the polymeric material configured to shrink when exposed to heat is PVC. 5. The compression collar of claim 1 , wherein the sleeve comprises two perforations positioned parallel to one another. 6. The compression collar of claim 1 , wherein the reinforcing ring is at least one of polyolefin, cross-linked polyolefin, polyethylene, cross-linked polyethylene, PEX, PEX-a, PEX-b, PEX-c, and PERT.
