Parker 372HB-8-4N Barbed Male Branch Tee 1/2in Barb 1/4in Npt

Product Description

The PARKER 372HB-8-4N is a single-barb male branch tee fitting designed for use in low-pressure fluid distribution systems. Constructed from white nylon, this fitting connects a 1/2 inch barbed tube to a 1/4 inch NPT male threaded port in a branch tee configuration. It accepts tubing with a 1/2 inch inside diameter and a 0.55 inch outside diameter. Rated to 125 psi maximum working pressure and rated for use from -40 degrees F to 200 degrees F, this fitting is built for reliable service in food-contact environments. It meets FDA compliance and NSF/ANSI 51 certification requirements, making it suitable where sanitary material standards are required.

This fitting is commonly used in beverage dispensing, food processing equipment, water filtration lines, and similar fluid-handling installations where tubing must branch off a threaded port. It is appropriate for residential and light commercial applications. Plumbers, refrigeration technicians, and equipment service professionals typically install this fitting in systems where flexible tubing meets a threaded male connection point. The branch tee geometry allows one inline flow path plus a lateral port off a single male NPT stub.

Compatibility

Designed for use with flexible tubing having a 1/2 inch inside diameter and 0.55 inch outside diameter, connecting to 1/4 inch NPT female threaded ports in food-grade and water-handling fluid systems.

Installation Notes

Installation is performed by a qualified plumber or equipment technician. Depressurize and drain the fluid system completely before removing or installing any fittings. Thread the NPT male end into the female port by hand first, then tighten with an appropriately sized wrench — do not overtighten nylon threads. Push tubing firmly onto the barb until it seats fully against the fitting shoulder, and confirm a leak-free joint before returning the system to service. Follow applicable plumbing codes and the equipment manufacturer's guidelines for fluid-system fittings.
