Parker 325HB-12-8N Barbed Tube Male Connector 3/4in Barb

Product Description

The PARKER 325HB-12-8N is a single-barb male tube connector designed for fluid transfer applications requiring a secure, leak-resistant connection between barbed tubing and NPT-threaded ports. Constructed from white nylon, this fitting accepts a 3/4 inch barb and threads into a 1/2 inch NPT female port. It carries FDA compliance and meets NSF/ANSI 51 standards, making it suitable for food-equipment and potable-water adjacent systems. Rated to 125 psi maximum working pressure, the fitting handles temperatures from -40 degrees F to 200 degrees F. Overall length measures 1.86 inches. Weight is 0.01 pounds.

This connector is used in residential and light commercial plumbing, HVAC condensate lines, food-service equipment, and fluid-handling assemblies where a barbed fitting must transition to a threaded port. The 3/4 inch barb accepts tubing with a 3/4 inch inside diameter and 0.8 inch outside diameter. Its nylon construction resists corrosion and is well suited for low-pressure water and compatible fluid systems. Licensed plumbers and HVAC technicians commonly install this fitting during equipment installation, maintenance, or repair.
