Food-Grade Silicone Paste 1 oz
Permatex 81101 is a translucent white silicone paste formulated to lubricate and condition O-rings, gaskets, seals, pressure plugs, valves, pool equipment and water faucets. It carries NSF H-1 certification for incidental food contact, making it suitable for kitchen and bathroom plumbing repairs. The one-ounce container serves both professional technicians and DIY users.
Temperature Stability and Chemical Resistance
The paste remains effective across a broad range from -50 °F to 550 °F (-45 °C to 288 °C) without melting, hardening or drying out. It resists common motor oils, engine fluids, heat and water while preventing rust and corrosion on compatible rubber and plastic components. This stability supports consistent sealing performance under sustained thermal cycling.
Non-Melting Formula for Long-Term Sealing
Because the compound does not melt at elevated temperatures, it stays in place on vertical or overhead fittings during normal operation. The flash point is 570 °F, indicating a high margin before ignition risk. The food-grade rating allows use on potable water systems without contaminating the supply, and the paste consistency reduces migration compared with thinner lubricants.

Questions about this item
How does the 81101 silicone paste handle continuous high-temperature exposure in a pump running all day?
The paste is non-melting and rated from -50 °F to 550 °F (-45 °C to 288 °C) with a flash point of 570 °F, so it remains stable during extended high-heat operation.
What mating surfaces or materials must already be in place for the 81101 paste to seal effectively?
It is designed for O-rings, gaskets, seals, pressure plugs, valves, weather stripping, pool pumps, filters and water faucet valves made from most rubbers and plastics.
Will the 81101 lubricant degrade older EPDM or nitrile seals already installed in my equipment?
The formula is compatible with most rubbers and plastics, resists common motor oils and engine fluids, and prevents rust and corrosion on aged components.
