Item Information PD Series Nipples (diagnostic test port connectors) up to 6,000 psi, connect with PD Series Couplers. These push to connect quick couplings provide easy connection for mechanical gauges or specialized diagnostic equipment including SensoControl meters and accessories. PD Series Nipples allow test instruments, gauges, transducers, and flow sensors to be quickly and easily connected to system test ports. Test port Nipples can be permanently mounted on equipment at critical test point locations. Couplers and nipples are available in 1/8"" size with a rated pressure of 6,000 psi when connected. PD Nipples meet or exceed SAE J1502 / ISO 15171-1 design and performance specifications.
