Parker 322HB-6N Barbed Tube Union Connector 3/8 Inch

Product Description

The PARKER 322HB-6N is a single-barb tube union connector designed to join two lengths of flexible tubing in fluid handling and distribution systems. Molded from white nylon, this straight union accepts 3/8-inch inside diameter tubing on both ends with a 0.43-inch outside diameter profile. It carries FDA compliance and NSF/ANSI 51 certification, making it appropriate for food equipment and potable water applications. The connector handles working pressures up to 125 psi and operates across a temperature range of -40 degrees F to 200 degrees F. Plumbers, HVAC technicians, and food-service equipment installers commonly use this fitting during new installations and service calls.

The PARKER 322HB-6N suits residential and light commercial applications where flexible tubing must be spliced or connected within tight spaces. Typical installations include ice makers, water filtration systems, beverage dispensing equipment, and HVAC condensate drain lines where NSF or FDA compliance is required. Its nylon construction resists corrosion and keeps weight minimal in low-pressure fluid circuits.

Key Features

• Single-barb design on both ends secures 3/8-inch ID flexible tubing without additional fittings
• Nylon construction provides corrosion resistance across a wide temperature range
• Rated to 125 psi working pressure for reliable performance in low-to-medium pressure circuits
• FDA compliant and NSF/ANSI 51 certified for food equipment and potable water contact applications
• Operating range of -40 degrees F to 200 degrees F suits both cold and hot fluid service
• Overall length of 1.61 inches allows installation in confined plumbing and equipment spaces

Compatibility

Designed for use with flexible tubing having a 3/8-inch inside diameter and a 0.43-inch outside diameter in low-pressure fluid handling systems requiring FDA or NSF/ANSI 51 compliance.

Installation Notes

Installation is typically performed by licensed plumbers or qualified HVAC or equipment service technicians. Shut off the water supply and relieve system pressure before disconnecting or installing any tubing fitting. Ensure tubing is cut cleanly and squarely, and push tubing fully onto each barb until it seats against the fitting body for a secure, leak-free connection. Verify that all materials and system pressures remain within the rated specifications for this fitting before returning the system to service.
