Precise Heater Seal. The 1968-81 Heater Core Firewall Seal Without Air Conditioning, 2", is designed to seal heater core tubes as they pass through the firewall. It provides a tight barrier that prevents leaks and ensures proper HVAC operation. This seal is essential for vehicles equipped with 2" thick heater cores without air conditioning to maintain optimal heating system performance.

Construction and Appearance. Made from dense, form-fitting molded foam, this seal replicates the original part for an exact fit. The foam compresses and conforms around the heater core tubes, delivering a secure and durable seal that resists heat and vibration over time.

Installation. Installation is simple and requires no drilling or modifications. The seal fits precisely into the firewall opening, allowing easy replacement of worn or damaged seals.

Application. Designed to fit specified models including Camaro, Chevy II & Nova, Chevelle & El Camino, GMC Sprint, Firebird, Buick Apollo and Skylark, Oldsmobile Omega, and Pontiac Ventura within the stated year ranges and exclusions. Suitable only for 2" thick heater cores without air conditioning.
