Parker 365HB-6N Barbed Tube Union Elbow 3/8 Inch Nylon

Product Description

The PARKER 365HB-6N is a single-barb union elbow fitting designed to connect two lengths of flexible tubing at a 90-degree angle without the need for threaded ends or clamps. Molded from white nylon, it accepts tubing with a 3/8 inch inner diameter and a 0.43 inch outer diameter on both sides. The fitting is rated to 125 psi maximum working pressure and handles temperatures from -40 degrees F to 200 degrees F, making it suitable for a wide range of fluid-handling and pneumatic line applications. It carries FDA compliance and meets NSF/ANSI 51 requirements for food-equipment materials. Plumbers, HVAC technicians, and equipment assemblers install this type of fitting in low-pressure tubing runs where a directional change is required.

This union elbow is used in residential and light commercial applications where flexible plastic tubing must change direction within a system. Common installation scenarios include condensate drain lines, water dispensing equipment, food-service machinery plumbing, and other fluid-transfer systems requiring NSF/ANSI 51 compliant components. The single-barb design on each port relies on the tubing material gripping the barb; a clamp or zip tie may be added for additional retention in higher-flow or pressurized runs.

Key Features

• Single barb on each port accepts 3/8 inch ID flexible tubing on both sides
• Nylon construction provides lightweight, corrosion-resistant performance
• Rated to 125 psi maximum working pressure
• Operating temperature range of -40 degrees F to 200 degrees F (-40 degrees C to 93.3 degrees C)
• FDA compliant and certified to NSF/ANSI 51 for food-equipment material safety
• White color aids visual identification in multi-line installations

Compatibility

Designed as an OEM-style push-on barb fitting for flexible plastic or rubber tubing with a 3/8 inch inner diameter and approximately 0.43 inch outer diameter. Verify tubing wall thickness and material compatibility with the fluid being conveyed before installation.

Installation Notes

Installation does not require special tools; the barbed ports are designed to accept tubing pushed firmly over each barb by hand. Shut off fluid supply and relieve system pressure before disconnecting or installing any fitting. For pressurized runs near the rated maximum, a stainless clamp or nylon zip tie over the tubing behind the barb is a common practice to prevent pull-off. Ensure tubing is cut cleanly and squarely so it seats fully against the barb shoulder for a leak-free connection.
