Which term refers to a preformed shape used to seal a joint or opening, typically made of rubber-like material?

• A. Lite
• B. Joint
• C. Fresh-cut PUR
• D. Lead-Free Frit

Answer: (D)

A preformed shape used to seal a joint or opening, made of rubber-like material, is best described as a gasket. A gasket’s job is to be compressed between two surfaces to fill gaps and prevent leaks, noise, or contamination. In auto glass work, gaskets or rubber seals are what keep water and air from infiltrating around the glass edges and help hold the pane in place.

Among the given options, the one that most closely aligns with the idea of sealing a joint is the term that refers to the interface where such a seal would sit. The other choices describe materials or products that aren’t used as preformed rubber seals: lead-free frit is a ceramic glaze on glass, fresh-cut PUR refers to polyurethane adhesive for bonding, and lite isn’t a term that denotes a sealing shape.
