BSPT Thread Ring Gauges

When utilizing BSPT thread, which is a general-purpose sealing pipe thread, sealing material must be added. The cost of BSPT threads is low, and only modest machining accuracy is required. Without using additional sealing material, a connection can be sealed using just the dry sealing pipe threads. The British pipe threads series does not include dry-sealing pipe threads. BSPT threads provide two primary purposes: mechanical connection and sealing. BSPT threads must meet higher accuracy standards than BSPP threads since BSPP threads only serve as mechanical connections.
