3" Hose barb x 3" MPT | HB300

Product Introduction

The Barr Plastics HB300 is a 3" Hose Barb x 3" Male Pipe Thread (MPT) fitting designed to join flexible hose to threaded pipe or valves. Made from durable plastic (commonly PVC or similar polymer), this 3" hose barb x 3" MPT adapter delivers corrosion resistance and reliable fluid transfer for irrigation, water handling, and light chemical service. Easy to install, the HB300 simplifies hose-to-pipe connections while providing a secure seal when used with hose clamps and standard thread sealant.

Features & Specifications

• Size: 3" hose barb inlet and 3" MPT outlet (HB300 model)
• Material: Durable plastic (PVC-type polymer) for corrosion and chemical resistance
• Connection types: Barb ribs for secure hose retention; 3" male pipe thread for standard female fittings
• Installation: Hose slips over barb and is secured with hose clamps; threaded side uses PTFE tape or pipe sealant
• Pressure rating: Suitable for moderate-pressure fluid transfer applications (verify against system pressure)
• Seal method: Use stainless hose clamps on the barb side; thread sealant or PTFE tape on MPT side
• Typical length: Standard barb profile for easy hose fit and clamp placement

Benefits & Applications

The HB300 solves common hose-to-pipe connection problems by combining a strong barb grip with a standard MPT thread. Its ribbed barb prevents hose slippage and leaks when paired with clamps, improving uptime in pumping and transfer systems. Because the fitting is plastic and corrosion-resistant, it’s ideal for agricultural irrigation, aquaculture water handling, wastewater and stormwater systems, HVAC low-pressure lines, and many chemical handling or processing tasks where compatible materials are required. For example, in a pond pump installation the HB300 provides a reliable 3" transition from pump outlet to flexible hose, reducing installation time and improving flow efficiency.

Always confirm chemical compatibility and system pressure before use. For best results, install with a properly sized hose clamp on the barb and PTFE tape or pipe sealant on the MPT threads.
