What is a parallel thread on a pipe?

• A. A thread that tapers at the end for sealing
• B. A thread that maintains the same diameter along its length
• C. A thread designed for compressing fittings
• D. A thread used for sealing only

Answer: (B)

A parallel thread on a pipe is characterized by maintaining the same diameter along its entire length. This type of threading contrasts with tapered threads, which gradually decrease in diameter towards the end. Parallel threads are typically used in certain applications such as connecting hoses, fittings, and valves, where a consistent diameter is crucial for ensuring compatibility with other components. While tapered threads are often designed to create a tight seal as they are screwed together, parallel threads do not have this feature. Instead, sealing is usually achieved with additional elements like O-rings or gaskets when using parallel threads. This understanding highlights the specific use and significance of parallel threads in various plumbing and mechanical systems, making them essential for applications that require straightforward, non-tapered connections.
