Parker 68HB-6-MI12 Barbed Hose Fitting 3/8 in Brass

Product Description

The PARKER 68HB-6-MI12 is a brass male connector barbed hose fitting designed to create a secure, leak-resistant transition between a flexible hose and a metric-threaded port. The fitting features a beaded hose barb on one end sized for 3/8 inch inside diameter hose and an M12 x 1.5 metric thread on the other end. Brass construction provides corrosion resistance suitable for water, air, and many fluid transfer applications. The hex head measures 0.6875 inches across flats for standard wrench installation. Rated for service between -40 and 160 degrees F, this fitting suits a wide range of HVAC, plumbing, and fluid-handling installations where a hose-to-metric-port connection is required.

This fitting is commonly used in residential and light commercial systems where a flexible hose must terminate at a metric-threaded fitting port. Typical applications include hydronic heating circuits, HVAC equipment connections, compressed air lines, and general fluid transfer assemblies. The beaded barb design helps retain the hose under pressure and reduces the risk of blow-off during normal system operation. Licensed plumbers, HVAC technicians, and pipefitters install this type of fitting as part of new construction and service work on equipment with metric port specifications.

Key Features

• Beaded hose barb improves hose retention and reduces blow-off risk
• M12 x 1.5 metric thread end connects directly to metric-ported equipment
• Sized for 3/8 inch inside diameter hose
• Brass construction resists corrosion in water, air, and common fluid service
• Hex head allows wrench tightening for a reliable, torque-controlled assembly
• Wide temperature range from -40 to 160 degrees F suits varied system environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 3/8 inch inside diameter hose with M12 x 1.5 metric-threaded ports.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off fluid flow and relieve system pressure completely before removing any existing fitting or installing this part. Use a wrench on the hex head to tighten the threaded end; do not over-tighten, as brass threads can be damaged by excessive force. Secure the hose over the barb with an appropriate clamp to maintain a leak-free connection at rated working conditions.
