Santech MT0297 A/C O-Ring 19 x 15 mm HNBR Seal

The Santech MT0297 is an A/C O-ring (also called an A/C system O-ring or air conditioning seal) that seals the connections between components in a vehicle's air conditioning system. A good seal helps keep refrigerant in the system and helps keep pressure and performance steady.

Key Features:

• Made from HNBR (hydrogenated nitrile butadiene rubber), which resists chemicals and heat
• Replaces worn or damaged O-rings at A/C line connections and fittings
• Built to meet or exceed OEM specifications for fit, form and function

Replace this O-ring whenever an A/C connection is opened for repair or component replacement. That helps prevent refrigerant leaks at the joint.
