Valco Gasket Sealer, Hylomar M Blue, 6.76 oz. Aerosol Can

Hylomar® is a polyester polyol–based compound that turns from a gel into flexible putty within minutes of application. Originally developed by Rolls Royce, where it performed under the most stringent aerospace tolerances, Hylomar brings superior qualities to automotive applications. Its non-hardening formula maintains seal integrity even when subjected to thermal distortion and vibration.
