Parker 372HB-3-2N Male Branch Tee 3/16 Barb 1/8 Npt

Product Description

The PARKER 372HB-3-2N is a male branch tee fitting designed for low-pressure tubing assemblies in fluid handling, pneumatic, and HVAC control line applications. Constructed from white nylon, this barbed fitting accepts 3/16 inch barbed tubing connections and features a 1/8 inch NPT male thread for direct port entry into manifolds, valves, or equipment housings. The branch tee configuration allows a single threaded port to split into two barbed outlets, making it well suited for distribution runs in control and instrumentation tubing systems. Plumbers, HVAC technicians, and fluid system assemblers install this fitting where a compact, lightweight plastic tee is appropriate for the service conditions.

This fitting is used in residential and light commercial applications involving low-pressure pneumatic controls, water treatment lines, laboratory fluid circuits, and similar systems where nylon construction is compatible with the fluid media. The 1/8 inch NPT male thread seals into a corresponding female NPT port, while the 3/16 inch barbs retain flexible tubing under normal operating conditions. It is commonly installed inline during system assembly or during service calls requiring a branch connection off an existing threaded port.

Key Features

• Male branch tee configuration splits one threaded port into two barbed tubing outlets
• 3/16 inch barb size accommodates standard flexible tubing of matching inside diameter
• 1/8 inch NPT male thread for direct installation into female NPT ports
• Nylon construction offers lightweight, corrosion-resistant performance in compatible fluid and air service
• White color finish for easy visual identification in multi-line installations

Compatibility

Designed as an OEM-style barbed branch tee for pneumatic and fluid control tubing systems using 3/16 inch flexible tubing and 1/8 inch NPT female threaded ports.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or instrumentation technicians. Shut off fluid or air supply and depressurize the system completely before removing or installing any fittings. Apply thread sealant tape or compound to the NPT male threads as required by applicable codes and the fluid service involved. Ensure barbed tubing connections are fully seated over the barbs and secured with appropriate clamps or retainers for the system pressure and media.
