S773 Triple Fin Adhesive Backed Perimeter Silicone Seal

The Pemko S773 is a perimeter adhesive backed seal made of high temperature silicone. Ideal for sealing larger gaps up to 3/8" wide. The S773 is easily compressible to 1/8", making it the perfect solution for uneven gaps that range from 1/8" to 3/8". The S773 is available in these lengths and colors:

Lengths: 17', 20', 250', and 500'
Colors: Black, White, Dark Brown, Light Gray
**Dark Brown is very dark, nearly black in color.

Function: The triple fin gasket design effectively blocks light, air, smoke, and sound from infiltrating a room.

Temperature Use: Stable between -58 degrees (F) and 450 degrees (F).

Fire/Smoke: Tested and approved under UL 10C for fire; UL 1784 for smoke and ASTM E90 and BS EN ISO 140-3 for sound control.

Air: Air infiltration tested in accordance with ASTM E-283-91. Air infiltration is only .09 CFM/ft. of crack.

Category H, J, and G: The S773 meets the requirements of Category H, J, and G.

Storage: Use within 6 months of purchase. Store between 50 to 10 degrees (F).

Installation Tips: Always scrape any residue from previous adhesive backed gasket and clean the surface with alcohol before applying the S773. Do not stretch the S773 during installation. Stretching will cover more linear feet, but the rubber will want to contract to the original length and will eventually pull the adhesive free from the surface.
