Parker FB6MCVC4-HBLK05 Inline Check Valve 1/4 in Ptc

Product Description

The PARKER FB6MCVC4-HBLK05 is an inline check valve designed for push-to-connect tubing installations in fluid handling and gas distribution systems. It accepts 3/8 inch outside diameter tubing on both ends and allows flow in one direction only, preventing backflow without additional fittings or tools. The valve carries a maximum working pressure of 300 psi and a crack pressure of 0.50 psi, making it responsive to low-differential conditions. The fluorocarbon seal compound provides resistance to a broad range of media. Licensed plumbers, HVAC technicians, and fluid system installers work with this valve in both light commercial and residential applications.

This check valve is suited for inline service on tubing runs where push-to-connect terminations are already in use. The black housing and compact form factor fit easily into tight mechanical spaces. It is rated from -17.80 degrees C up to 250 degrees F, covering most standard process and HVAC tubing environments. NSF/ANSI 51 and NSF/ANSI 61 certification makes it appropriate for potable water and food equipment contact applications where compliance is required.
