Technical Information
Momentive RTV159 Red High Strain Silicone Electrical Sealant in the 6 oz cartridge format delivers the same high-elongation silicone electrical sealant performance as the 2.8 oz tube in a larger cartridge format suited for medium-scale connector sealing and production operations. The high-strain silicone polymer resists cracking under vibration, thermal cycling, and mechanical flexing, making it ideal for sealing military and aerospace electrical connectors, wire harness terminations, and sensor interfaces. The 6 oz format reduces tube-change frequency in production environments while maintaining the precision application characteristics required for connector sealing work.
Why Choose RTV159?
- 6 oz Cartridge Format — Larger quantity for production connector sealing with fewer changeovers
- High-Strain Silicone — Resists cracking under vibration and mechanical movement
- Red Color ID — Distinguishable from gray RTV157 for multi-connector assemblies
- Aerospace & Defense Grade — Trusted for military and aerospace electrical connector sealing
- Superior Dielectric Properties — Maintains electrical insulation integrity in sealed connections
