Unique-Bargains Silicone Sealing Rod 39" 18mm Red High-Temp

SKU CH-EJ5V-TSKFP

Red silicone sealing rod withstands -70 °C to 250 °C and suits door or window gaskets

  • Withstands 482 °F for extreme heat sealing
  • Remains flexible down to -94 °F in freezing conditions
  • 39-inch length lets you cut custom gaskets
  • 18 mm diameter fits standard machinery grooves
  • Red silicone resists ozone, oil and aging

18 mm Silicone Sealing Rod

This 39" long solid round rod is made from high-temperature resistant silicone. It operates across a range of -94°F (-70°C) to 482°F (250°C). The material offers high elasticity, low odor, and resistance to aging, ozone, and deformation. It is suited for creating custom seals in machinery and automotive applications.

For Custom Gasket Fabrication

The rod suits technicians who need to splice specific diameter sealing rings for equipment doors, windows, or hydraulic systems. It handles exposure to mild acids, alkalis, and oils without degrading. Buyers needing a flat strip, hollow tube, or adhesive-backed profile should look at alternative profiles. The solid 18 mm cross-section limits use in tight grooves or low-compression spaces.

39 Inch Length and Thermal Headroom

The one-meter length yields multiple large-diameter rings or several smaller gaskets with minimal waste. It comfortably withstands continuous heat up to 482°F in exhaust, ignition, or hydraulic environments. The material runs out when a profile other than a solid 18 mm round is required, or when lengths exceeding 39" are needed without joining.

Questions about this item

What temperature extremes can the 18mm red silicone rod withstand in my application?

The rod operates continuously from -94°F (-70°C) up to 482°F (250°C), so it survives both deep-freeze and high-heat environments without degrading.

Will the 39-inch length and 0.71-inch diameter fit the groove in my existing equipment door or window frame?

The solid round profile measures 39 inches long by 18mm (0.71") in diameter; you can cut it to exact length and splice ends to form a custom sealing ring for your groove.

How can I confirm the seal is performing correctly after installation?

Check for a uniform, gap-free seat in the channel, verify the red strip remains flexible and shows no cracking or permanent set after the first heat cycle, and ensure no leakage or drafts occur at operating temperature.
