Parker 329HB-12-8PP Barbed Male Elbow 3/4in Barb 1/2in Npt

Product Description

The PARKER 329HB-12-8PP is a single-barb male elbow fitting designed to connect flexible tubing to a threaded male NPT port at a 90-degree angle. Constructed from black polypropylene, this fitting accepts 3/4 inch inside diameter tubing and threads into a 1/2 inch NPT female port. It is rated for working pressures up to 125 psi and handles temperatures from 0 degrees F to 212 degrees F, making it suitable for a wide range of fluid transfer applications. The fitting meets FDA compliance and NSF/ANSI 51 standards, qualifying it for use in food equipment and potable water-adjacent systems. Plumbers, HVAC technicians, and fluid system installers work with this fitting type.

This fitting is used in residential and light commercial plumbing, HVAC condensate and fluid handling lines, pool and spa plumbing, and food service equipment installations. The single-barb design grips flexible tubing securely when used with an appropriate hose clamp or cinch ring. The male NPT thread allows direct installation into female-threaded ports on valves, manifolds, pumps, or equipment housings. It is a practical choice wherever a rigid-to-flexible transition is needed at a right-angle junction.

Installation Notes

This fitting is typically installed by licensed plumbers or HVAC technicians in accordance with applicable IPC or IFGC guidelines for fluid system connections. Shut off flow and depressurize the line before installation. Apply thread sealant or PTFE tape to the male NPT threads before making up the connection; do not overtighten, as polypropylene threads can crack under excessive torque. Secure the barbed end with an appropriate hose clamp or cinch ring sized for the tubing outside diameter.
