What type of pipe uses elastomeric gaskets?

• A. Plastic
• B. Concrete
• C. Steel
• D. Cast Iron

Answer: (B)

Elastomeric gaskets provide a flexible, compressible seal between pipe sections, allowing the joint to stay watertight as soil settles and temperatures change. Concrete pipe commonly uses bell-and-spigot joints that rely on these rubber-like gaskets to seal the joint effectively, filling irregularities and accommodating movement. While gaskets can be used with other materials as well, the typical association in this context is concrete pipe, where the gasketed joint is a standard method to achieve a durable, leak-free seal.
