Federal Mogul MOGUL-68N (19MMx15MT)

Silicone Tape 68N

Overview

Silicone Tape 68N is a self-amalgamating, fiberglass-reinforced silicone elastomer tape engineered for high-temperature aerospace wire harness protection and sealing. Manufactured by Bentley-Harris (Federal-Mogul Systems Protection), it provides durable mechanical protection, excellent fluid resistance, and reliable sealing of harness sleeves and connection accessories. Designed for continuous operation from -60°C to +260°C, 68N is widely specified for aerospace electrical systems where thermal protection and environmental sealing are critical.

Key Features & Benefits

• Self-amalgamating design forms a continuous protective seal without adhesive.
• Fiberglass reinforcement improves mechanical durability at elevated temperatures.
• Excellent resistance to aviation fuels, hydraulic fluids, mineral oils and synthetic oils.
• Withstands continuous operating temperatures up to 260°C.
• Easy installation without specialised tools.
• Provides neat, professional wire harness finishing.
• Offers reliable local mechanical and environmental protection.
• Suitable for demanding aerospace electrical applications.

Application Guidelines

• Wrap the tape under light tension around the component requiring protection.
• Apply overlapping wraps to achieve complete coverage and sealing.
• Light pressure allows the silicone tape to self-amalgamate over several hours at ambient temperature.
• For optimum amalgamation, allow sufficient time according to the operating temperature.
• Ensure surfaces are clean and dry before application.
• No adhesive or additional bonding agents are required.

Compatibility & Limitations

• Compatible with aerospace wire harness sleeving and connection accessories.
• Excellent resistance to Jet Fuel (JP5), Skydrol® hydraulic fluid, mineral oils and synthetic oils.
• Suitable for aircraft electrical and mechanical protection applications.
• Intended primarily for local protection and sealing rather than structural repair.
• Store in a cool, dark location away from heat sources.
