Gates Polarseal Male Inverted O-Ring Bulkhead Coupling

The Gates PolarSeal Male Inverted O-Ring Bulkhead Coupling is a hose end fitting for PolarSeal air conditioning hose. It lets you run an A/C line through a panel, firewall or bracket, and it gives you a male inverted O-ring (MIO) connection on the threaded end. The bulkhead design is also called a bulkhead fitting or bulkhead coupler. It is used in automotive, heavy-duty and off-highway A/C and refrigerant hose assemblies.

Key Features:

• Male inverted O-ring (MIO) connection for a secure, leak-resistant seal
• Bulkhead style for passing a line through a panel or mounting point
• Made by Gates to work as a system with PolarSeal A/C hose
• PolarSeal couplings and hose are designed to resist heat, moisture, chemicals and ozone
• Available in aluminum and steel construction across the product line

Pairing Gates PolarSeal couplings with matching PolarSeal hose helps the assembly fit well and perform reliably over time. Check the individual part listing for O-ring requirements, since some couplings in this line do not include the O-ring.
