The NORGREN C00040600 is a push-to-connect plug-style tube fitting manufactured from Polybutylene Terephthalate (PBT) plastic. It is designed to seal and cap off a pneumatic or fluid line with a 6mm outside-diameter tube, eliminating flow through an unused port without tools. The fitting is rated to 260 psi and uses a Nitrile o-ring for the internal seal, making it suitable for air lines and compatible fluid systems. Plumbers, pipefitters, and pneumatic system technicians install this type of fitting during system commissioning, port isolation, or maintenance shutdowns.
This plug fitting is used in pneumatic control panels, compressed-air distribution networks, and fluid handling assemblies where a 6mm OD tube port must be capped or terminated. Its push-to-connect design allows fast, tool-free installation and removal, reducing labor time during panel builds or field service. It is appropriate for both light industrial and commercial applications where PBT plastic construction meets the temperature and chemical requirements of the system.
Designed as an OEM-style push-to-connect plug for pneumatic and fluid systems using 6mm outside-diameter tubing where a capped or terminated port is required.
Depressurize and isolate the pneumatic or fluid circuit completely before installing or removing this fitting. Inspect the tube end for squareness and freedom from burrs before pushing it fully into the fitting body to ensure a leak-free seal. This fitting is intended for installation by qualified pipefitters, pneumatic technicians, or plumbers familiar with push-to-connect system practices. Do not exceed the rated working pressure of 260 psi.
