PD Series Tube End Nipple - Seal-Lok

PD Series couplings are designed for quick, reliable connections to mechanical gauges and specialized diagnostic tools like SensoControl. PD or BPD nipples are typically installed permanently in systems—mounted at threaded test ports, within rigid tubing, or integrated into hose assemblies. When it’s time to test, PD Series couplers easily connect to these fixed nipples without the need for threading, allowing gauges, transducers, and other instruments to snap into place effortlessly. This streamlined connection method simplifies pressure checks and system diagnostics, reducing downtime and improving testing efficiency.
