On direct contact, uncured silicone sealant irritates eyes. In case of contact, flush eyes
with water and seek medical attention. In case of skin contact, wipe off and flush with
water.
e.
Silicone Sealant. Silicone sealant is often used instead of a gasket to seal mating parts. The mating parts
must be clean, dry and free of oil or grease for proper adhesion. After silicone sealant has been applied, the mating
parts must be assembled immediately. Silicone sealant starts to set-up in 15 minutes and takes 24 hours to
completely cure. Excess silicone sealant should be wiped off after assembling the mating parts.
f.
Gaskets. Remove all traces of previous gasket and sealant before installing new gasket. Coat both sides of
gasket with sealant to provide added sealing.

hose connections or fittings with preformed packings. Damage to equipment may result.
