Parker 322HB-10N Barbed Tube Union Connector 5/8 Inch

Product Description

The PARKER 322HB-10N is a single-barb tube union connector designed to join two lengths of flexible tubing in fluid-handling systems. Molded from nylon and finished in white, this straight union fitting accepts tubing with a 5/8 inch inside diameter and a 0.67 inch outside diameter on both ends. It carries a maximum working pressure of 125 psi and an operating temperature range of -40 degrees F to 200 degrees F, making it suitable for a broad range of liquid transfer applications. The fitting meets FDA Compliant and NSF/ANSI 51 standards, qualifying it for use in food-equipment and potable-water contact environments. Licensed plumbers, refrigeration mechanics, and equipment technicians are the primary installers.

This union connector is used in residential and light commercial applications where two runs of flexible tubing must be joined inline without the use of threaded or push-to-connect fittings. Typical scenarios include beverage dispensing equipment, food-service machinery, water filtration assemblies, and potable-water supply lines where NSF/ANSI 51 compliance is required. The nylon construction offers adequate chemical resistance for clean water and many food-grade fluid circuits. The overall length of 1.73 inches keeps the fitting compact within tight equipment enclosures.

Compatibility

Designed for use with flexible tubing having a 5/8 inch inside diameter and a 0.67 inch outside diameter. Suitable for food-service, beverage dispensing, and potable-water filtration systems where FDA and NSF/ANSI 51 compliance is required.

Installation Notes

Installation is typically performed by licensed plumbers or qualified equipment technicians. Shut off the fluid supply and relieve system pressure completely before disconnecting or connecting tubing. Push the tubing firmly over each barb until it seats fully against the fitting shoulder; the barbs provide retention but clamps are recommended at or near maximum working pressure. Verify that the tubing material and durometer are compatible with the fluid, temperature, and pressure conditions of the application before placing the fitting into service.
